FFX400 1mRMZ1-R (CU/MGT+XLPE/LSZH/SWA/LSZH 600/1000V Class 2)

APPLICATION

This cable is designed for areas where the integrity of the electrical properties circuit is critical in maintaining

power supply. 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.
