Power cables with aluminium conductors and PVC insulation for 0.66/1 kV
Power cables for a rated voltage of 0.66/1 kV with stranded aluminium conductors and polyvinyl chloride compound insulation. TCG production complies with GOST 31996-2012. Aluminium cables are lighter than copper ones and considerably cheaper — the optimal solution for distribution networks, trunk lines and substation supply. The category includes AVVG, the armoured AVBShv and the fire-safe AVVGng(A)-LS.
