600/1000V Mica+XLPE Insulated LSZH Sheathed Fire Resistant Power Cable – IEC 60502-1

600/1000V Mica+XLPE Insulated, LSZH Sheathed Fire Resistant Power Cable

Product Overview

The 600/1000V Mica+XLPE Insulated, LSZH Sheathed Fire Resistant Power Cable is designed for areas where the integrity of the electrical circuit is critical in maintaining power supply during a fire emergency. The combination of mica glass tape and cross-linked XLPE insulation provides exceptional fire resistance, while the thermoplastic LSZH outer sheath ensures low smoke and zero halogen emissions.

Applications can be found in emergency lightings, control and power circuits, power stations, fire alarm systems, underground tunnels, communications systems, sewage treatment plants, lifts, escalators, and high-rise buildings.

The basic design conforms to IEC 60502-1, ensuring suitability for low voltage power distribution in critical safety installations.
