IEC 60502-2 HYPRON® Armoured (SWA) Fire retardant

Applications

These power cables are used for electricity supply in medium voltage installation system. They are well adapted to underground use in industrial applications, in moist areas, where hydrocarbons and mechanical protections are needed. Hypron® offers an alternative to conventional lead covered cable and is an environmental friendly solution.
