Control cable KVVGEng of 0,66 kV

Design:
1. Conductor – copper, single-wire, class 1
2. Insulation – made of polyvinyl chloride plastic (PVC).
3. Stranding – the insulated conductors of the cables are stranded. Each layer contains a counting pair, the insulated veins of which differ in color from each other and from the rest of the veins.
4. Separating layer – applied to twisted conductors made of polyethylene terephthalate film or PVC compound with a thickness of at least 0.5 mm, in cables of the KVVGEng brands and made of PVC compound of low flammability with a thickness of at least 0.5 mm.
5. Screen – in the form of a winding of copper foil or copper tape with a nominal thickness of 0.06 mm, or an aluminum foil with a nominal thickness of 0.1 0.15 mm with an overlap to ensure the continuity of the screen at permissible bending radii of the cables. It is allowed to manufacture the screen from corrugated aluminum strips applied longitudinally with overlapping. A copper wire with a diameter of 0.4 – 0.6 mm is laid longitudinally along the screen made of aluminum foil.
6. Sheath – PVC compound which does not support combustion.

Application:
Designed for fixed connection to electrical devices, devices, assemblies of clamps of electrical switchgear with rated alternating voltage up to 660 V, frequency up to 100 Hz or constant voltage up to 1000 V, for laying in rooms, channels, tunnels in the absence of mechanical stress on the cable in aggressive conditions environment and the need to protect electrical circuits from the influence of external electric fields. KVVGEng cables are used for laying in cable structures and premises to ensure fire safety of cable chains when laying in bundles.
