Description

Standards

  • Product
    BS 7870-4.10 ; IEC 60502-2

Application

Triplex MV cable suitable for outdoor and indoor installation, in air, in grounds, and in cable ducts.

The cable is suitable for rated voltage 6/10KV (Um=12KV) according to the IEC standards.

Construction

The cable is consisted of 3 single core cables which are bunched together in triplex formation.

Each single core cable is consisted of solid (class 1) or stranded (class 2) with or without water protection Aluminium conductor, conductor screen of semiconducting compound, XLPE insulation, insulation screen of semiconducting compound, , copper wires metallic screen, PE outer sheath. Three single core cables are laid-up together in triplex formation.
