Where this standard is used on NirmanDost

Listed by product makers

5 products in the NirmanDost catalogue name this standard on their spec sheets — Finopower 3.8/6.6 kV (E) Grade Three Core Armoured Cables with Aluminium Conductors, A2XCEFY, Finopower 6.35/11 kV (E) or 6.6/6.6 kV (UE) Grade Three Core Armoured Cables with Aluminium Conductors, A2XCEFY, Finopower 11/11 kV (UE) Grade Three Core Armoured Cables with Aluminium Conductors, A2XCEFY. That is the maker’s own claim, copied as printed; we have not tested these products against the standard, and a spec sheet can cite the wrong code.
