- 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.

Cables are not dangerous on their own, but they may sometimes cause fires resulting from bad or ageing installations, wrong calculations of sections, and poor-quality cables installed, etc
Due to the use of organic materials for insulation and sheathing and their huge volume in buildings, during fires, cables can also severely contribute to:
In order to save people and goods from these risks, Nexans offers halogen-free cables which prevent fire propagation and dramatically reduce the emission of smoke and hazardous, acidic, and irritant gases, thus allowing people time to exit safely.
