Power cable VVGng, VVG-Png (ВВГнг, ВВГ-Пнг)

Power cable with aluminum cores in PVC insulation, in sheath from PVC plasticate that do not propagate fire

 

VVGng is intended for electric energy transmission and distribution in stationary equipment (between introductory and distributing boards or boxes) at nominal alternated voltage 0,66 kV and 1 kV and frequency of 50 Hz. The cable is intended for laying in ground, in cable ducts, in dry and wet production areas and also for outdoor laying where is strong need in protection against mechanical damage and in the mounted bunch without emission of burning. Foreign equivalent of the cable can be found here.

 

Quality is regulated by:

GOST 16442-80, TU U 3.67-00217099.3-94.

 

Structure :

  1. 1. Core – aluminum, round or sector form with cross-sectional area from 1,5 mm² - 240 mm²;
  2. 2. Insulation - insulated PVC plasticate;
  3. 3. Sheath - PVC plasticate with low fire risk;
  4. 4. Quantity of cores - one insulated or stranded from 2-5 cores.

 

Specifications:

  • operating temperature from -50 ºС up to +50 ºС;
  • maximum permissible reheat temperature of cores during operation +70 ºС;
  • maximum permissible reheat temperature of cores in malfunction +80 ºС (with duration of work not more than 8 hours per day and 1000 hours for the whole period of exploitation);
  • maximum temperature at short circuit – +160 ºС;
  • installation and laying of cables without the preheating realizes with the temperature not lower than -15°С;
