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.

Low-voltage cables

LV trailing cables 0,6/1 kV in two sheath design is designed for special application condition in wind turbines. The construction is torsion resistance by free hanging max. 100 m. The cables are specified for medium mechanical stress and for operation under permanent influence of seawater and outdoor usage.

Medium-voltage cables

  • Onshore underground single-core cables (typically 33 kV) connect the rows of wind turbines and, in parallel, links them to an onshore substation
  • Offshore cost-efficientsubmarine 3-core copper cables with integrated fiber optic elements and customized armor designs to link the turbines.

 High-voltage cables for transmission

  • Onshore AC transmission: cables ranging from 60 kV to 500 kV, XLPE insulated, are used for power transmission from the onshore windpark substa...
