Power cables with aluminium conductors and XLPE insulation for 0.66/1 kV
Power cables for a rated voltage of 0.66/1 kV with stranded aluminium conductors and cross-linked polyethylene (XLPE) insulation. They combine two advantages: the cost efficiency of aluminium (~3× lighter and cheaper than copper) and the improved thermal performance of XLPE (+90°C continuously vs +70°C for PVC — giving +20–25% continuous current-carrying capacity). TCG production complies with GOST 31996-2012. The category includes APvVG, the armoured APvBShv and the fire-safe APvVGng(A)-LS.
