Conductor
Copper or aluminum, single-wire or multi-wire, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483.
Insulation
Is made of PVC-compound (color coded conductor).
Core arrangement
Insulated conductors of multi-core cables are twisted in a cable core.
Inner sheath
It is made by extrusion with PVC-compound of low flammability or chalk-filled non-cured rubber with the filling of outer gaps between insulated conductors. It is possible to fill the outer gaps between circular insulated cores with the bundles of with the lapping of fastening tape and extrusion inner sheath. It is allowed to wrap the cable core with the tapes of polymer material.
Taping
Is made of tape or tapes of conductive paper or conductive synthetic tape, or tapes of non-woven conductive fabric. In waterproof cables – a layer of water blocking tapes.
Screen
Of copper wires and a spirally imposed copper tape. It is allowed the application of the screen with copper tapes.
Separating layer
Of polymer tape or non-woven fabric. In waterproof cables – a layer of water blocking tapes.
Bedding
Of PVC-compound of low flammability.
Cable armoring
Is lapped helically with two steel, galvanized tapes.
Over sheath
Of PVC-compound of low flammability.
The cables are designed for transmission and distribution of electric power at the stationary installation on the nominal alternating voltage 6kV of frequency 50 Hz for networks with the earthed and insulated neutral.
The climate modification УХЛ, categories of location 1 and 5 according to GOST 15150, including installation in the ground.
The class of fire hazard of the cables according to GOST 31565 П1б.8.2.5.4.
