PVC wires

PVC wires

— the marking PVS corresponds to the term "copper wire in PVC insulation for connection." Both the outer sheath and the insulation of each core in such a cable are made of polyvinyl chloride. The key difference from VVG (see the corresponding section), which also uses PVC, is that the sheath is solid and fills all the space between the cores. Additionally, the cores themselves are made only of multi-wire strands.

Thanks to all these features, one of the main advantages of PVS wires is excellent flexibility. This type of cable not only bends easily but also withstands repeated bending and unbending, including fairly sharp ones. Such properties are indispensable for power cords used in various household electrical appliances, as well as in extension cords; in fact, this is the main area of application for PVS. Another area of use is lighting systems, sockets, etc., where a cable with high flexibility may be required. The disadvantage of this wire is its sensitivity to low temperatures — under such conditions, the PVC sheath loses elasticity and may crack.

PVS cable is designed for alternating current with a standard frequency of 50 Hz and voltage values up to 380 V.
