NYY-LS FE 180 / NYCY-LS FE 180

General information

These Cables cables of this trademark are used for transmission and distribution of electric power in case of fire (for providing power supply to fire safety chains and fire extinguishing pumps, lighting of evacuation and emergency exits, evacuation lifts, air ventilation, explosive zones, operating units of hospitals).

STRUCTURE

  1. An electric conductor
  2. Thermal barrier from mica tapes
  3. PVC insulation with low smoke and gas emission
  4. Filling with low smoke and gas emission
  5. Copper braid or wire shield (for NYCY-LS FE 180)
  6. PVC shell with low smoke and gas emission

The structure of the cable can vary depending on the duration of fire resistance when exposed to an open flame.
