IEC 60502 STA Armoured Electrical Cable Three Core For Underground Use

IEC 60502 STA Armoured Electrical Cable Three Core for underground use

Application

PVC power cable for static outdoor application (with protection against direct UV-irradiation), in ground, in water, within facilities, in cable canals, in concrete, in conditions where heavier mechanical loads and specially tensile strains, are not expected. Used in electric power plants, transformer stations, industrial plants, metropolitan networks and in other electric plants, same as for connection of signalling devices in industry, traffic and similar.
