Our two leading types of medium-voltage cable are XLPE (cross-linked polyethylene) and EPR (Ethylene Propylene Rubber). The former is used worldwide, while the latter is mainly for selected markets.

From a design point of view, medium-voltage cables are of three types:

  • single-core cable,
  • three single-core cables laid-up,
  • three-core cable.

Nexans cables are custom designed to meet your high performance standards.

   
XLPE insulated
Outdoor Energy cables/Land High Voltage cables

Since the late 1960s we have been developing an entire range of XLPE (cross-linked polyethylene) insulated cables for high voltage-transmission.

This kind of cable consists of a stranded copper or aluminum conductor with an extruded insulation system which is further protected by a metallic shield and an outer sheath. In submarine applications, the cable is normally designed with a lead sheath and outer steel-wire armor

XLPE cables are predominantly used in underground networks, but  are gradually replacing traditional paper-insulated, fluid-impregnated cables undersea, as well.

They have several distinct advantages:

 

  • Flexibility, lightness and strength
  • No need for an auxiliary fluid-pressure system
  • Low maintenance compared to fluid-impregnated cables
  • Simpler accessories
