RG Cable Types: Uses, Differences, and How to Identify Them
RG Cables are a type of coaxial cable that are essential for powering televisions, CCTV cameras, and more. Over the years there have been a few different iterations of RG cable, but the most commonly used types with today’s technology are RG59 and RG6.This article will outline how RG59 and RG6 cables are used, the differences between each type, and how they can be identified.What Are the Differences Between RG59 and RG6?There are a few key differences between RG59 and RG6 cables, namely in the construction. In general, RG6 is produced to achieve a higher level of protection against signal loss; for example, it features thicker insulation and better shielding than RG59. It also features a conductor with a heavier AWG than RG59, which means that signal transfer is better in RG6.All of these features allow for a reduction in signal loss for RG6 cables. RG59 Cables are also protected against signal loss, but to a lesser extent (see the table below) – instead, their draw is that they are more cost-effective than RG6 cables.RG Cable Attenuation RatesAttenuation refers to the loss of signal strength from within the cable. For example, a cable with higher attenuation means that it transfers a weaker signal than a cable with lower attenuation.The attenuation rates of RG59 versus RG6 cables are shown in the table below:Speed (MHz)Signal loss (dB) per 100ftRG59RG6502.41.51003.42.04007.04.390011.16.8100012.07.0 What Are RG59 and RG6 Cables Used For?While both cable types are suited to a wide range of applications including TV, CCTV, and Internet, some applications are better suited to RG59 than RG6 and vice versa.Generally, RG6 cables are better performing than RG59 in terms of bandwidth and frequency, so they are more suited for high-speed applications such as TV and Internet. RG59, on the other hand, suffer from more signal loss that RG6, so are more suited to lower-bandwidth, lower-frequency applications such as CCTV and other analogue video systems.Ultimately, the type of cable you should get depends on the type of application for which you’re intending to use it. If you’re looking for cables for a lower-quality CCTV camera, then RG59 is your best bet, as you don’t want a cable that is too advanced for the system that you’ll be using it for. If you’re looking for a cable to carry a more high-definition video signal, like for your television, then we’d recommend an RG6 cable.If you’d like to know more about our RG59 and/or RG6 cables, or have any unanswered questions, then click here to get in contact with our team.
Is Cat5 or Coax Better for CCTV?
For CCTV applications, there are a few different kinds of cables that fit the job, but one of the main questions you’ll be sure to encounter is – which is better for your CCTV system, Cat5 or Coax?In this guide, we’ll go over what each type of cable does, as well as the features and benefits of each, so that you’re as informed as possible to decide which is best for you.What is Cat5?Cat5 is a type of data cable that is most often used for internet and networking applications, for example in large offices or other areas where lots of computers need to access the same network. This being said, Cat5 can also be used for video applications, for example CCTV.Features & Benefits of Cat5 CablesCat5 cables are available in a few different varieties, but the main ones used today are FTP and U/UTP.‘FTP’ stands for Foiled Twisted Pairs, meaning that each individual pair of twisted wires is wrapped in a protective foil shield. This prevents the wires from electrical interference and crosstalk with adjacent pairs or other nearby cables.‘U/UTP’ stands for Unshielded Twisted Pairs, so while there is no shielding within the cable, the twisted wire pairs create a balanced transmission line and prevent crosstalk between adjacent pairs and other nearby cables.There are a few benefits to using Cat5 cables for CCTV applications. The main advantage is that Cat5 allows for long-distance video transmission – it can be used in runs over 1000m! Cat5 cables can also be used both to power the camera and transmit the video signal in the same run, whereas coaxial cables will need a separate power cable.  Finally, Cat5 cables tend to be more cost-effective than coax cables.What is Coax?Coaxial cables, known in the industry simply as coax, are a type of cable featuring a shielded design, which allows the copper core to transmit data as quickly as possible without signal loss. Coax has been used in the industry for years, powering both low- and high- speed video applications, depending on the cable.Features & Benefits of CoaxCoax cables generally feature a high-quality copper core within shielding, which helps to transmit the video signal as quickly as possible without signal loss. They’re also available in shotgun constructions if this is needed, with a power cable.The main benefit of using Coaxial cables for CCTV is that they’re as durable and high-quality as alternative cables whilst also being cost-effective. A shotgun cable is a particularly cost-effective choice for CCTV, as it allows the camera to both be powered, and show and record video without needing to buy more than one cable.Which Cable is Best for CCTV?The decision as to which type of cable should be used for CCTV applications ultimately falls to what your priorities are. Coax cables have been the industry standard for CCTV for years, so it’s clearly a reliable option. However, Cat5 cables have become more popular in recent years, and if you’re looking for cables for long-distance applications, Cat5 may be your best bet.If you have any further questions or would like to learn more about our cables, then click here to speak to someone from our friendly team.

How Far can you Run Coaxial Cable for CCTV?
Most home CCTV systems can use standard-issue RG cables. However, if you’re looking for a CCTV system for a larger building, then you may want to consider some other options.In this handy guide, we’ll go over which cables are suitable for extended distance applications.How Far Should I Run A Coax Cable?As a hard and fast rule, coaxial cables are not recommended for applications over…It’s not recommended that coax cables are used for extended distance applications. The main problem with using standard-issue RG coaxial cables for long distance applications is that, in long distance runs the cable undergoes something called signal loss, known in the industry as attenuation. This happens when the signal being transmitted leaks from within the cable, cause the signal to be less strong.As you can see from the table below, attenuation rates differ depending on the type of coaxial cable, and increase as the length and bandwidth of the cable increases.Coax Cable Attenuation Loss Chart (per 100ft)Loss (MHz)Coax Cable Attenuation per 100ft (dB)RG59RG6RG1110.40.20.2101.40.60.4503.31.41.01004.92.01.62007.32.82.340011.24.33.570016.95.64.790020.16.05.4100021.56.15.6Which Cables Can I Use for Extended Distance?If you’re looking to for a high-bandwidth signal to be carried over a long distance, we’d recommend looking into Extended Distance Coaxial Cables. These cables are constructed with an additional layer of protective shielding around the conductor, so that less signal is lost over long distances.Have any further questions about our coax cables?

Can Coaxial Cables be Used for Power?
Coaxial Cables are most commonly used for video applications, such as television and CCTV. However, because they’re constructed specifically to be protected against signal loss, they can be used for other applications too.In this guide, we’ll help you to understand the types of cables that can be used for power.Can I Use A Coaxial Cable for Power?While coaxial cables are most often used for carrying video signals, you might be surprised to learn that it’s a common practice in the engineering industry to also use them to power small-scale electronics. Coaxial cables feature high-quality shielding and insulation to ensure a reduction in signal loss outside the cable, so can be an ideal choice if you’re particularly concerned about signal loss.However, the reason why this isn’t standard practice is because coaxial cables can be more expensive than other cables that can be used in the same application.There are also coaxial cables that feature a shotgun style construction, meaning that there are two connected cables sold as a pair. One cable is an RG cable, and the other is a power cable – this way, if you’re looking to power a video system, one cable will power the video system, and the other will carry the video signal.What Other Cables Can Be Used for Power?The types of cable that are ordinarily used for power are simply referred to as power cables. They are used to transmit electrical power from one location to another.There are a few different types of power cables – to view our helpful guide on the types of power cable, click here.If you’re looking for a power cable for an application where it’ll be moved around once installed, we recommend Flexible Power Cables. These are constructed specifically to withstand the daily wear and tear that a cable undergoes if constantly flexed or moved around; for example, a regular Power Cable may experience breaks in the shielding, insulation, or even the sheathing if flexed too much.If you have any questions that weren’t answered in this article, please click here to contact our team of experts.
Core Materials Guide
In the majority of cases, the electrical cabling around your home or business will contain pure copper, or at least mostly copper wire.The properties of these cables can vary due to the sheathing or insulation used, but cables can also perform differently when their cores are made from alternative metals.Here are some of the most common core materials available.Pure Metal CoresCopperCopper is one of the highest standard materials used for electrical conductors. Although not quite as conductive as silver, copper is a far more economical and widely supplied material, making it the standard for most cabling applications.Sometimes, copper can be hard to solder unless a ‘flux’ is used – this is a compound used in the soldering process that cleans the surface in preparation for bonding. Using a flux can result in corrosive residues being left behind, so in some cases, copper will be tinned or plated to avoid this – see more about copper-clad cables below.Pure copper, however, is the gold standard of conduction and is suited for pressure terminations too. Copper is also incredibly malleable and can be bent into any shape or direction - although the sheathing material used can have limitations on this ability.AluminiumAluminium is favoured for cable conductors due to its lightweight nature. It is slightly less conductive than copper, but when balancing this with its weight, performs on a similar level.Aluminium is also relatively inexpensive, but cannot be soldered easily, so is often plated with copper to gain the benefits of both materials in a single wire.SilverSilver is an incredibly good conductor, better than copper in fact. It is, however, substantially more expensive. Silver-plated wire is more common, as it utilises the conductive benefits of silver and allows the wire to operate over a wide temperature range (from -65°C to 200°C).There are a few niche uses where silver’s extremely low resistance is a key element – scientific instruments and cryogenics may utilise pure silver conductors for this reason.GoldGold is a common form of plating for brass connector pins – though it’s not that commonly used for cables due to the expense of the materials.Easily soldered, gold has good corrosion resistance. It’s not as good a conductor as copper and silver, but resists oxidation far better, which is why it is used as a plated layer to protect some inner components.Tinned CableTin is generally not used on its own as a cable conductor, but is used as corrosion protection for copper without affecting its conductivity. Coating a copper cable in tin can also make it far easier to solder.Nickel-PlatedNickel-plated wire also operates in extreme conditions over a wide temperature range. If the nickel-plating is thick, it can withstand temperatures up to 750°C. Nickel also acts as an excellent layer of corrosion resistance.Metal Clad CoresCopper Clad AluminiumCopper clad aluminium cable is aluminium cable plated in copper. This makes the cable less expensive than pure copper, but lighter too, as aluminium in itself is an incredibly lightweight material.However, CCA cable allows the aluminium element to gain more electrical conductivity when combining this with copper, as well as adding to the strength of pure aluminium.Copper Clad SteelCopper clad steel is comprised of a steel wire plated with copper. As copper is more expensive than steel, it allows the cable to combine the benefits of both materials for a lower price.CCS cable is not quite as conductive as pure copper, but this level of conductivity is not needed in every application. Copper clad steel wire has double the mechanical strength of solid copper wire, giving it longevity in harsher environments and under frequent movement.For more information about our range of cables, get in touch with our friendly team.
Braiding vs Screening vs Shielding
Cables use screening and shielding to protect the cable and add resistance to interference from other cables or devices.Many people often get confused between braiding, shielding, screening and other terms, so we’ve made a handy guide to what all of these types of protection mean! Shielding or Screening?Shielding and screening are the same! They are both a protective layer added over the conductors to protect the cable from, or prevent it from causing, electrical interference. Disturbance can cause lower quality signal or data loss and can therefore result in equipment failure, therefore it is essential to choose the right screening for the right purpose.Shielding and screening come in many different forms, each with a specific purpose.Types of ShieldingBraidingBraiding is when cables are woven in a lattice of thin tin or copper wire, looking like a braid as the name suggests.The coverage of the braid (often referred to as the density) depends on the number of strands or wires within each plait. It also depends on the thickness of the braid strands. The diameter of the braid wires also specifies the level of damage the cable can withstand.Braiding is used for mechanical protection against any electrical or electromagnetic interference, as well as to add strength to the cable. Braiding is usually applied either over the inner sheath if there is one, or directly over the core bundle.Braiding can be applied in different materials for very specific purposes:Copper - used for screening against electromagnetic interference Steel - used for mechanical protection Glass or Ceramic fibres - used for high temperature environments Rayon - used for torsional strength Although braided shielding can be more costly and time consuming to produce, it is flexible and versatile, and performs well at all frequency types.FoilingFoil screening involves wrapping the cable cores in aluminium or polyester laminated tape to increase durability. The foils must be in contact with a bare wire to act as an earthing point.Foil shielding can offer up to 100% coverage and can withstand high-frequency applications. It's also quick, cost-effective and easy to produce due to its lightweight nature.However it is slightly less durable than traditional braiding, so it is not recommended to use foil shielding in areas where a lot of flex is needed.ArmouringArmouring is not a form of screening, but it is a common method of protection for cables. It is often constructed by winding galvanised steel wires over the cable in the form of a spiral.Armouring is often used when cables are to be laid in an outside environment - it prevents vermin and termites from attacking and damaging the cable.Though armoured cable can be less flexible and harder to terminate, there is no better way to protect a cable from this sort of interference.For more information about cable screening, get in touch with our friendly team, or shop our wide range of cables today.
Sheathing Material Guide
With a wide range of cable sheathing options available, it’s hard to know which is best for your installation.A range of factors from population density, temperature and flexibility can all impact your choice of cable.Take a look at our guide and find out all the benefits and drawbacks of the most common sheath materials on the market! PVCPVC, or polyvinyl chloride, is one of the most common sheathing options for cables. It’s low-cost to manufacture, as well as offering durability, flexibility and resistance to oil and water.PVC is suitable only for indoor use as it is vulnerable to UV light and can become brittle when exposed to bright sunlight. It gives off harmful halogen gases when burned, so is not suitable for densely populated buildings or in any situation where it may be exposed to fire.PEPE (polyethylene) is an excellent choice for outdoor cable installations, such as those involving direct burial. When UV stabilised, the material provides great resistance to moisture and extreme weather.PE is tough and rigid in comparison to other sheathing counterparts, and it does not burn but melts and reforms when cool, making it a safer option too. PE sheathing is commonly used for data transmission cables.RubberRubber is one of the most popular material choices for sheathing. It is waterproof, flexible and chemically resistant.Since rubber is more of a high-cost material, sometimes synthetic rubber compounds are used to mimic the effect without such a high price.Rubber sheathing is used when an installation requires water resistance and flexibility in extreme temperatures.LSFLSF stands for ‘Low Smoke and Fume’. This material is a modified PVC material that produces less gas and smoke than traditional PVC when the polymer is burnt.LSF sheathed cables do not meet the highest standard of fire safety (see LSZH cables) as they can still emit up to 22% Hydrogen Chloride gas, however they do meet further standards than standard PVC sheathing would (up to 28%).LSZHLSZH (Low Smoke Zero Halogen) cables are also known as ‘LS0H’ and ‘0HLS’ (Zero Halogen Low Smoke) are similar to PVC but behave differently in the event of exposure to fire.The main feature of these cables is that they do not release large amounts of toxic fumes or smoke when burned. Their fire retardance is much higher, making them often used in commercial or densely populated buildings due to their better quality and safety elements – anything they release is not harmful to humans when burned. This also means they conform to higher fire regulations than many other cables.SiliconeSilicone is a sheathing material that can operate from –50 to 180 degrees Celsius. It is resistant to heat, chemicals and even bacteria growth, making is a great choice for installations in food or medical environments.Silicone boasts UV resistance and does not produce any harmful smoke or gases when burned.This sheathing material is more expensive than most to produce and has limited options for recycling at its end of life, which doesn’t make it the best choice for everyday cabling. However, for specialist applications, its benefits cannot be beaten.PURPUR stands for polyurethane, a material that offers great chemical and mechanical resistance.PUR can be used in temperatures between –40 and 125 degrees Celsius. Some blends can be halogen free and flame retardant, but this depends entirely on the specific make up.Much like silicone, the material is resistant to bacteria growth and can therefore be used in food or medical-grade installations.PTFEPTFE, or Teflon, is a material used in applications that involve extreme temperatures or corrosive environments.Its benefits are that the material is non-toxic and environmentally friendly, as well as being flexible and non-flammable, making it a safe option for many installations.PTFE boasts thermal, chemical and electrical resistance. It can operate between –75 degrees Celsius and up to 200 degrees Celsius. It is also unaffected by most fuels, oils and fluids.FEPFEP is a fluoropolymer incredibly similar to PTFE, with similar benefits such as the ability to operate in extreme temperatures and low chemical reactivity.NeopreneNeoprene is a form of synthetic rubber. The sheathing material provides oil and chemical resistance, as well as strength and flexibility at lower temperatures.NylonNylon is an incredibly abrasive and chemically resistant material for sheathing, though less flexible that its counterparts.For more help or information regarding sheathing, get in touch with our team!
Enhancing Safety - LSF vs LSZH
Understanding The Key Differences Between LSF and LSZH Cable Sheaths:In the intricate realm of the electrical industry, safety remains an unwavering priority.Amongst the many components that contribute to safety, cable sheaths play a crucial role in containing potential hazards during fire incidents.Two essential terms commonly used amongst the electrical industry are "LSF" (Low Smoke and Fume) and "LSZH" (Low Smoke Zero Halogen).While they may appear similar, it is crucial to understand the difference and purposes of each cable sheath material.Securi-Flex® knows it's important to understand the differences between the two materials. In this article, we'll examine these differences more closely.LSF Cables:Manufacturers produce LSF cables using a modified PVC compound that produces less HCL gas and smoke than regular PVC cables. LSF cables create between 15-22% of HCL gas and emit black smoke because of the presence of PVC. It is vital not to confuse LSF cables with LSZH cables, as LSF cables do contain halogen materials. They are often chosen as a cost alternative to LSZH, however they should not be confused with LSZH cables. They are not recommended for use in public or commercial buildings, as well as poorly ventilated areas. LSZH Cables:LSZH cables are manufactured using halogen-free compounds. They are effective fire retardants while emitting less than 0.5% hydrogen chloride gas and smoke when burned. During a fire, LSZH cables produce small amounts of light grey smoke and HCL gas. The absence of PVC in LSZH cables ensures no harmful fumes or black smoke are emitted during the event of a fire. Ideal for public buildings such as airports, railway stations (London Underground), computer rooms, and data centres. Low smoke generation ensures evacuation routes and signage remain visible during emergencies. Choosing the Right Cable:The choice between LSF, and LSZH cables depends on the fire risk, flexibility needs, and safety considerations.LSF cables offer a slight improvement over PVC cables but can still emit toxic gases and dense black smoke.However, LSZH cables reduce emissions and experts recommend them for high-risk areas.The CPR categorises cables by fire performance, however it doesn't cover toxic fumes and smoke.Installers must carefully choose cables appropriate for the specific fire risks in a building or application.In Summary:Understanding the differences between LSF and LSZH cables is vital for making informed decisions that prioritise safety in different scenarios.While LSF cables can offer cost advantages, they may not be suitable for critical areas, where LSZH cables are strongly recommended to ensure a safer environment during the event of a fire.Choosing the right cable can significantly contribute to enhancing overall fire safety and exposure.If you have any questions that weren't answered in this article, please do not hesitate to get in touch with our friendly team.We're always happy to help!

What Is a Twinaxial Cable?
Understanding Twinaxial Cables: How Do They Differ from Coaxial Cables?In data transmission and networking, type of cables play a role in ensuring information travels seamlessly from one point to another.Twinaxial cables, often referred to as "twinax" cables, have gained popularity for their unique characteristics and capabilities.A Twinaxial cable, commonly known as a "Twinax" cable, is a type of electrical cable used for transmitting data and signals.The name "Twinax" comes from its' construction, involving two inner conductors insulated from each other and enclosed by an outer shielding.The term "Twinaxial" is a portmanteau of "twin" and "coaxial," reflecting the cable's unique design. What is the Construction of Twinaxial Cables?Inner Conductors - At the core of a Twinaxial cable are two conductors, usually made of copper. Two conductors twist together, similar to how Ethernet cables feature twisted pairs. The twisting helps reduce electromagnetic interference (EMI) and crosstalk between the conductors. Insulation - Insulating each inner conductor individually prevents electrical contact between them. Manufacturers use various materials for this insulation, including polyethylene (PE) or foam dielectric. Shielding - Surrounding the insulated conductors is a metallic shielding layer, often made of braided copper or aluminium foil. This shielding provides protection against external EMI and ensures signal integrity. Outer Jacket - A protective jacket made of PVC or a similar material encases the cable inside. This jacket safeguards the internal components from physical damage, moisture, and environmental factors.  How do Twinaxial Cables Work?Twinaxial cables are well-suited for high-frequency signal transmission. When an electrical signal runs through the inner conductors, the twisted design reduces the electromagnetic fields produced by the current flow. This design reduces signal loss, crosstalk, and interference, allowing for efficient data transmission, especially over relatively long distances.Twinaxial cables frequently find use in high-speed data transfer applications like computer networking, video transmission, and connecting data storage devices. What is the difference between Twinaxial Cables & Coaxial Cables?Twinaxial cables share some similarities with coaxial cables, another common choice for data transmission, but they also have distinct differences:Structure - Coaxial cables feature a single inner conductor, enclosed by an insulator and a metallic shielding layer. Twinaxial cables, on the other hand, have two closely spaced inner conductors. EMI and Crosstalk - Twinaxial cables are better at minimising EMI and crosstalk because of their twisted pair configuration. Coaxial cables are also effective at this, but Twinaxial cables have an edge in certain high-frequency applications.  The following applications use Coaxial Cables:Broadcasting Cable Television High-frequency RF applications Networking, Computer Connections, and data storage connections favour Twinaxial cables. In Summary:Twinaxial cables are a unique and effective solution for high-speed data transmission, offering low EMI and crosstalk.Their construction, with two closely spaced conductors and shielding, sets them apart from coaxial cables.Understanding the differences between these cable types helps you chose the most suitable option for your specific application.Securi-Flex® offer a range of Twinaxial Cables which are available directly from stock.If you have more questions, feel free to contact our friendly team.
