TwitterSafety cables
These 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.

Low fire hazard cables <1kV Indoor energy cables/Wires and cables <1kV A low level of opacity of smoke produced and acidity of the effluent are basic criteria in the selection of materials that, in the event of fire, make it possible to reduce the presence of dangerous gases and to facilitate escape. It is essential that the production of opaque smoke and harmful emissions is as low as possible during a fire. Nexans’ offer enables to:
