300/500V Mica+XLPE Insulated, LSZH Sheathed Power Cables (Single Core)

FFX300 05mRZ1-R (CU/MGT+XLPE/LSZH 300/500V Class 2)

FFX300 05mRZ1-R (CU/MGT+XLPE/LSZH 300/500V Class 2)

APPLICATION
These 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.
