CONSTRUCTION:
1. Electric conductor – copper single or multiwire, round or sectoral shape, according to 1 or 2 grade, GOST 22483.
2. Insulation from polyvinylchloride compound. Core – insulated conductors twisted between each other. Inner сore interval from insulated conductors filled with harness, pressed from low fire hazard polyvinylchloride compound. Multiwire cables have equal section conductors. Four conductor cables with section 25 mm2 and more may have one conductor smaller section (neutral or ground conductor).
3. Inner sheath from low fire hazard polyvinylchloride compound, laid with filling spaces between insulated conductors.
4. Outer sheath from low fire hazard polyvinylchloride compound

Power cables with copper conductors, insulation and sheath from polyvinylchloride compound, low smoke and gas emissions flame-retardant, grades VVGng(A)-LS used for transmission and distribution of electric energy in stationary units at nominal alternating voltage 0,66 and 1 kV, nominal frequency 50 Hz or at direct voltage up to 1 and 1,5 kV.
Electric networks with ground or insulated neutral in which operating time of single-phase short circuit to ground not exceed 8 hours, overall operating time of single-phase short circuit to ground not exceed 125 hours per year. Cables can be laid without limitation of level differences on the routing, including vertical areas.
Maximum network voltage for operating cables Um equals to 1,2U.
Cables could be used for direct voltage electric networks, not exceeding 2,4U0.
Cables used for bunched laying including hot loading volume in cable structures and outer (open) electric units in case of mechanical damages and absence of tension force during operating procedures.
Fire hazard grade acc.to GOST 31565: P1b.8.2.2.2.
