Safety cables

  • Safety cableThese cables can still be PVC insulated for tramways, and generally are halogen-free, low smoke and fire-retardant for subways.
  • They are mainly used for traction, station equipment (lighting, escalator, automatic doors) and tunnels (ventilation).
  • Cables for emergency equipment are also fire-resistant for circuit integrity, e.g. to keep alarms and essential services operating during a fire.
  • High requirements for fire retardancy or even fire resistance are met by several product ranges of low-voltage cables in different sizes under various brand names, like Alsecure Premium®, e.g. core ceramifiable cables.

Nexans supplies armored safety cables under a longstanding contract with France’s RATP, operator of the Paris Metro, as well as the London Underground.

低火灾风险电缆 1kV
室内布线/电线和电缆 1kV

电缆本身并不危险,但有时会由于不良安装或老化,横截面计算错误以及电缆质量不佳等原因而引起火灾

由于绝缘和护套使用了有机材料,并且其在建筑物中体积巨大,因此在火灾期间,电缆还会严重导致:

烟雾量增多,限制能见度并阻碍逃生
增大一氧化碳的产生,这是火灾中最致命的气体
释放刺激性气体
为了挽救火灾中的生命以及物品,耐克森提供了不含卤素的电缆,可以防止火情扩散,并且显著降低烟雾排放和危险的酸性及刺激性气体,从而让人有时间安全地逃生。
