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.
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.
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.
