3 Types of XTRA Guard Multi-pair Cables

XTRA Guard Multi-pair Cables A multi pair cable has more than one conductor in them. Each of these conductors is also covered in a PVC insulation. This is to extend the life of the cable. The multi pair cables are most commonly used for high technology applications, medial electronics, point of sale equipment, computer peripherals and industrial controls.


The unshielded multi pair cable is the more basic version of these cables. It still does have the same temperature range rating. It is also approved to be able to handle 300 volts of electricity. The only difference between this and the shielded version is the shield. This cable has the conductors wrapped in a PVC jacket and then the conductors are all wrapped together in another PVC jacket. The cables also are made with a nylon rip cord to make it easy to get the jacket off.


Shielded Multi-pair Cables The XTRA Guard shielded cable is approved for 300 volts of electricity. The cables come in a range of sizes starting at 24 AWG and going all the way up to size 18 AWG. They have all stranded copper conductors. The shield on this cable is made out of three layers, aluminum, polyester, and aluminum again. This gives the wire added protection against interference from other wires that could be in close contact. The temperature rating for the cable is between -20°C and up to 80°C.

SUPRA Shielded

The SUPRA shielded version of the XTRA Guard multi pair cords is very similar to the others. It has the same intended uses and it’s even made of the same materials. There is however a difference between the standard shield and the SUPRA shield. The SUPRA shield has even more added protection for the conductors. The SUPRA shield is made of layers of aluminum, polyester, aluminum foil shield with a 70% braid shield. The braid gives the cable added protection from EMI.

The XTRA Guard multi pair cables have devoted their energy to flame and moisture resistance, fast and easy stripping of the jacket and being used in flexible cable routing systems. Plus the cables are all both UL and CSA approved. Each cable has a different level of protection against outside interference. The cables with shields are better protected than the unshielded version. Then the SUPRA shielded cable is even better protected than the shielded cable. However each cable is approved for the same uses and they are all made with the same materials.

Type ET High Temperature Wire Construction

Type ET High Temperature WireThere are many different kinds of high temperature wire. The type ET wire however has a silver plated copper conductor. Then there is the PTFE insulation wrapped around the wire. Between the silver plating and the insulation that is what allows this wire to be able to withstand such high temperatures. The fact that these wires can withstand such high temperatures make them ideal for use in electrical work as well as in electronics.

Bare Copper Strands

When it comes to a copper conductor the more strands of copper there are the more flexible the wire can become. If there is a solid bare copper conductor than there is not a lot of flexibility, then the larger the size of the wire, the harder the copper becomes to bend if it will even bend at all. The smaller strands make for a better and more flexible wire.

Silver Coating

The silver coating on the copper helps the wire to have a longer life. The silver on the copper helps to prevent corrosion in high temperatures. This is what makes the silver plated wire the ideal choice for high frequency and high temperature wire. The wire is rated to be able to handle temperatures reaching as high as 200°C. It is also rated to be able to handle 250 volts of electricity. The wire also meets all of the M16878/6 approvals.

PTFE Insulation

The PTFE insulation is what allows the wire to be used for high temperature applications. This kind of insulation is non-stick and feeling slippery, it is intended to be used for electrical or electronic usage.  The insulation helps to prevent thermal aging, solder iron damage, as well as resist flame and moisture damage. It is also very resistant to solvents, greases, ozone, and a lot of other chemicals. With the insulation being so resistant to so many different things this wire is going to work well in many different environments and applications.

The PTFE insulation is great. It protects the wire from almost anything that can be spilt on it. The insulation also helps to make sure that the wire can withstand the high temperatures of the environment it was intended for. The slick insulation also allows for quick and easy installation of the wires.  Type ET wire also has excellent, stable electrical characteristic with low power loss which makes it ideal for high frequency applications. The silver plated copper will last longer than a regular copper wire because the silver adds protection and prolongs the life of the wire.

3 Hook Up Wire Acronyms to Remember

3 Hook Up Wire Acronyms to RememberThere are so many acronyms that are used when talking about wire and cables. The three most common are PVC, PTFE, and THHN. Each acronym refers to a kind of insulation or jacket that is wrapped around the copper wire. For the most part each of these forms of insulation are pretty much the same. Each kind of insulation has its own unique temperature rating. And each wire can only handle a specific level of voltage.



PVC stands for polyvinyl chloride. This is the most basic and the least expensive kind of hook up wire. It is generally used indoors and in electronics. The wire has a temperature rating of 105°C. The wire is also approved and rated to be able to handle either 300 or 600 volts; this depends on the wire which you choose to purchase.


PFTE stands for polytetrafluoroethylene. This insulation will do all the same things as the PVC insulation. The main difference between the two is that the PTFE insulation is approved for high temperature uses. The PTFE wire has been rated to be handle temperatures as high as 200°C. This insulation is slick and a non-stick so it’s easier to install than the average PVC wire. The PTFE insulation on the wire is resistant to a number of substances. They are resistant to solvents, greases, ozone, and most other chemicals. This allows the PTFE wires to be able to be used in all kinds of environments not just around the house.


THHN stands for thermoplastic high heat nylon. This wire is not flexible like the PVC and the PTFE wires. This THHN wire is used more in houses and buildings to connect electricity to lights, outlets and appliances around the home. The THHN wires are made with a soft drawn bare copper conductor and have PVC with nylon jacket. This allows the wires to be resistant to both gasoline and oils. The wires have been rated to be able to handle 600 volts of electricity. They also meet the UL listed standards and can be made with the CSA approval upon request.

Each of these acronyms refers to a specific kind of jacket or insulation that is wrapped around the copper conductor of the wire. These three are the most commonly used acronyms as well as the three most common forms of insulation for a wire. The PVC is the most basic and the cheapest form of insulation but it will get the job done and is protective of the copper conductor. Then there is the PTFE insulation that is intended to be used in places where there is a need for protection against high temperatures. Then finally there is the THHN insulation is not flexible. It is better used in giving electricity to appliances and outlets throughout the house.

Copper XHHW Wire VS Aluminum XHHW Wire

There are two kinds of XHHW wire. The copper conductor wire and the aluminum conductor wire. They both generally have the same uses. Everything about the wire is the same as far as temperature rating, volts, and what the wire is resistant to because they have the same insulation. These wires no matter which conductor you choose are very resistant to chemicals, ozone, and abrasions.

XHHW Insulation

This insulation type is what is going to cover either the copper or aluminum wire strands. This kind of insulation makes the wires fire resistant. This is due to its cross linked polyethylene material. The insulation also makes the wires water resistant. The wires with this insulation are usually used in residential, commercial, and even industrial buildings. XHHW wires are installed for the purpose of power distribution. Most XHHW wires are approved for at most between 110 and 600 volts. They usually range in size between a 14 AWG and a size 1000 MCM.

Copper Wire

Copper XHHW WireThe copper wire is heavier and much more expensive than the aluminum wire. At the same time the copper is a much better conductor of electricity than the aluminum wire. The XHHW wire is approved for up to 600 volts and 90°C temperatures. These wires are typically used in conduit, raceway, and is also suitable for use in health care facilities. It is considered a sunlight resistant electrical wire. The copper conductor can come in both stranded and solid versions, with the stranded version being much more flexible than the solid.

Aluminum Wire

Aluminum XHHW WireAluminum is very light. Unfortunately it is also less conductive than the copper is. For example, a connection in need of 100 AMPS will need a bigger AWG size of aluminum than the copper wire.  This kind of XHHW aluminum wire is rated to withstand temperatures up to 90°C. The wire is UL approved and it is also RoHS compliant. The aluminum wire is usually used in branch and circuit electrical wiring.

Both wires have the same insulation so as far as environmental uses go they will end up being the same for both wires. You want to make sure to speak to your electrician about your application because aluminum cables are not always approved where copper cables are. The aluminum and copper wires both come in stranded and solid options. The bigger gauge size of the wire the stranded may become your only option because the wire will need some flexibility.
