Fire Resisting Cables
Fire Resistant Power & Control Cables
300/500V Mica+XLPE Insulated, LSZH Sheathed Power Cables (Single Core)
FFX300 05mRZ1-R (CU/MGT+XLPE/LSZH 300/500V Class 2)
Application:
The cables are designed for areas where the integrity of the electrical 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, lifts, escalators, and high-rise buildings.
Standards:
Basic design to IEC 60502-1
