Fire retardant or fire resistant Medium-voltage power and feeder cables

  • In  Metro projects, more and more MV feeder cables are now requested with improved Fire Retardancy (Acc. To IEC 60332-3-22 Cat A or B) or even with some guarantees of service continuity during fire, thus based upon IEC 60331, but with application of the operation voltage.

Nexans has supplied fire resisting MV cables for the subways of Amsterdam and Budapest. Technologies based upon mica protection tapes or silicon insulation can apply, depending upon precise electrical and environmental requirements.

Power Network Cabling/Medium Voltage

Our two leading types of medium-voltage cables 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 cables,
  • three single-core cables laid-up (triplex),
  • three-core cables.

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