STRUCTURE

Conductor

Copper, single-wire, of the 1 class according to GOST 22483, with the cross-section from 1.5 to 6 mm2.

Insulation

For cables of types KPvBShvng(A)-LS – cross-linked, halogen free polymer composition.

For cables of types KPBShvng(A)-LS – thermoplastic, cross-linked, halogen free polymer composition.

Core arrangement and twisting

Number of conductors from 4 to 61.

The insulated conductors are twisted in a cable core.

The cables have a digital and color coded marking of the conductors.

Inner sheath

It is made by extrusion with filling with the halogen free polymer compositions.

Cable armoring

It is laid helically with two steel, galvanized tapes.

It is possible to lay the PET-tapes by winding or longitudinally over the armor.

Cable sheath or jacket

PVC-compound of low fire hazard.
