PVC Cable (Polyvinyl chloride) is widely used in electrical cable construction for insulation, bedding and sheathing. These cables are manufactured for a voltage range of 1kV to 3.3kV for IEC and BS specifications. The copper conductors are of higher purity and conductivity is drawn and annealed to stringent specification

Cable with a PVC insulation or sheathing is flame retardant, which is an important consideration for electric cables in most applications. There are thermoset versions of PVC Cable which are cross-linked, typically with electron beam technology but they are more expensive to use and so when specified they are typically in high-spec applications in industries such as defence and automotive. The thermoset or cross-linked PVC has improved temperature resistance, is tougher, and has a better dielectric strength, which means that a thinner coating or insulation layer can be applied making the overall cable dimension smaller.
