Description

Standards

  • Product
    DIN VDE 0276 part 620; IEC 60502-2

Application

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

 

Construction

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

Each single core cable is consisted of stranded aluminium conductor, conductor screen of semiconducting compound, insulation of cross-linked polyethylene (XLPE), screen of semiconducting compound, semiconducting tape, screen of copper wires and copper tape, longitudinal water protection, separation tape, PE sheath. Three single core cables are laid-up together in triplex formation.
