The service life of the long-life wire can reach 81.3 years at 70 ° C and 76.2 years at 85 ° C.

The use of double-layer co-extrusion technology, the internal insulation using irradiation crosslinked polyethylene to increase the electrical performance of the wire, the external insulation using irradiation crosslinked halogen-free low smoke flame retardant polyolefin insulation material to increase the mechanical properties of the wire, in the event of fire on the wire fire will automatically extinguish, prevent the spread of the fire. When burned, the cable will not release toxic gases and will reduce smoke emissions.
