Structure

Conductor – aluminium or copper, single or multi-wire, round or sector shaped, class 1, 2 as per national standard GOST 22483-77. The number of conductors: 2-5. 4-conductor cables may have 3 conductors of the same area and one conductor of smaller area (ground or neutral one).
Insulation – PVC plastic compound. Insulated multi-conductor cables carry identification coloring. Grounding conductor insulation is in two colors (green-yellow). Neutral conductor insulation is blue.
Stranding – insulated conductors are stranded to form a cable core. In the sector conductor cables PET film tape is applied over stranded conductors.
Belt Insulation: PVC plastic compound of low combustibility.
Protective covering: БбШв type: armour of two steel zinc-coated tapes; protective hose of PVC plastic compound of low flammability.

Аpplication

The cables are designed for power transmission and distribution in stationary equipment for nominal alternating voltage 0,66 kV and 1kV, frequency 50Hz.

The cables are used for installing in the ground (trenches), indoor (incl. fire-dangerous), tunnels, ducts and mines (except cable blocks), as well as outdoor if there is a danger of mechanical damage while operating but if cable is not exposed to considerable stretching effects.

The cables are flame-retardent while bundled installation.
