Three-core medium voltage energy cables with stranded copper conductors, PROTOTHEN®-X (XLPE) insulation, special inner and outer semi-conductive layers on conductors and insulation, copper tape screen on each core, armour of galvanized flat steel wires and helix steel binding tape and PROTODUR® (PVC) outer sheath.
These cables are produced according to TS IEC 60502-2
- Permissible operating temperature: 90 ºC
- Permissible short-circuit temperature: 250 ºC
(for short circuit duration up to 5 sec.)
These cables have very low electrical loss compare to their similars and they are used in cable ducts, outdoor an indoor installations, underground where the short circuit levels are hight such as urban and industrial areas fed by electrical energy. They are also used under normal and salty water if specially produced.
