Safety 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.
