VVGng rated for 660, 1000 V electric cable

Assembly:
1. Conductor copper, single or multiwire, round- or sector-shaped, 1 or 2 class as per GOST 22483. 
2. Insulation PVC. Insulated multiconductor cable conductors carry identification coloring. Neutral conductor insulation is blue. Grounding conductor insulation is in two colors (yellow-green). 
3. Twisting Insulated conductors of two-, three-, four-, and five- conductor cables are twisted. Two conductor cables feature conductors of the same area. Three-, four-, and five- conductor cables feature all the conductors of the same area or one conductor (ground or neutral one ) of a smaller area. 
4. Jacket PVC, VVng cables are sheathed with flameretardant PVC.

Application:
These cables are intended for distributing electric power in fixed installations rated for nominal alternating voltages of 0.66 KV and 1 KV 50 Hz. They are meant for laying inside both dry and wet industrial premises on special trestles, in assemblies as well as for laying outdoors. Cables are not recommended for burying in trenches.
VVG cables are flameretardant if laid individually.
VVGng cables are flameretardant if laid in bunches.
