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.
