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 and fastened by polypropylene thread (for sectoral conductors). Insulated
conductors of multiwire cables have distinct colouring. Neutral conductor insulation has
blue colouring. Grounding conductor insulation has two-colouring (green-yellow). Inner
сore interval from insulated conductors filled with harness, pressed from polyvinylchloride
compound.
3. Inner sheath from polyvinylchloride compound.
4. Outer sheath from polyvinylchloride compound.
For cable grade VVGng(A) inner and outer sheath from low-flammable polyvinylchloride
compound
Power cables with copper conductors, insulation and sheath from polyvinylchloride compound, grade VVG, VVGng(A) 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 the nominal 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.
VVG cables used for single cable lines laying in structures and outer (open) electric units (cable tray system, galleries) Bunched laying of such cables necessary to use fireproof equipment.
Cable grades VVGng(A) used for bunched laying in cable structures of outer (open) electric units (cable tray system, galleries).
Fire hazard grade for cable grade VVG acc.to GOST 31565: O.1.8.2.5.4
Fire hazard grade for cable grade VVGng(A) acc. to GOST 31565: P16.8.2.5.4.
