Long life wires and cables

High performance long-life wires and cables adopt the cable process and technology used in nuclear power plants, double-layer insulation structure and irradiation cross-linking process (the insulation and sheath are all radiation cross-linked), which ensures the mechanical and physical properties, electrical properties and Low smoke zero halogen flame resistance of the cable, and extends the service life of the cable. The characteristics of high performance and long lifespan. Long service life wires and cables have characteristics such as halogen-free, low smoke, flame retardant, fire-resistant, non-toxic, long service life, high operating temperature, and high current carrying capacity. The service life of the product at 70 ℃ shall not be less than 70 years. Working temperature: The long-term allowable operating temperature of cable conductors is 90 ° C, 105C, 125 ℃; The maximum operating temperature during a short circuit (maximum duration of 5 seconds) is 250C; Laying temperature: It is not recommended to lay cables when the ambient temperature is below 0 ° C, otherwise heating measures should be taken; Bending radius: Minimum allowable bending radius of the cable: Single core cable: 20D without armor, 15D with armor, multi-core cable: 15D without armor, 12D with armor.

Scope of application for long-life wires and cables

High life wires and cables are suitable for distribution networks or industrial installations with rated voltages of 0.6/1kV and below, and can be used in all densely populated public places such as shopping malls, theaters, stations, airports, etc
