High temperature flexible power cables

High temperature flexible power cables

  • FLAMEX® SI power cables are particularly recommended where high temperature is required to save cable weight.
  • Designed to conform to EN 50382, they can withstand extreme temperature (from -50°C to 150°C) while offering significant weight savings compared to regular power cables.
  • A 140°C conductor temperature is allowed for a 20,000 hours cumulative working time for 120°C types.
  • Thanks to their high flexibility these cables are easy to install in narrow space.

European standard EN 50 382 deals with high temperature rolling stock power cables having special fire performance: flame and fire retardant, halogenfree, low smoke emission, low toxicity and low corrosivity of fumes.
A 140°C conductor temperature is allowed for a 20.000 hours cumulate working time.

Developed by the Nexans R&D laboratories, silicone materials show an excellent mechanical resistance to abrasion, tensile strength and cut through, but also a very good resistance to chemical agents.
Flexible and easy to strip, our cables are designed to meet the stringent requirements of our customers during cabling operations.

Nexans proposes to rolling stock manufacturers 3 cable series of FLAMEX® up to -50°C.

  1. Type F: with only insulation This type could be manufactured with tinned or plain copper conductor. Silicon rubber made in Nexans plant overlaps requirements of EN 50 382-1 standard; and brin...
