The 240mm fire rated copper mica XLPE LSHF (Low Smoke Halogen Free) flame retardant high security cable is a power transmission cable specially designed for high safety demand scenarios, integrating multiple safety performances.​ The conductor of the cable is made of high-purity copper, which has excellent conductivity, ensuring efficient and stable power transmission and meeting the electricity demand of high-power equipment. Its insulation layer is composed of mica tape and XLPE composite. The mica tape has strong high-temperature resistance and fireproof performance, which can maintain insulation effect for a long time in fire environment. XLPE enhances electrical insulation and mechanical strength. The combination of the two greatly improves the flame retardant grade and safety of the cable. The outer layer is made of LSHF material, which will not release toxic and harmful gases and a large amount of smoke when burning, which can reduce secondary damage in fire and gain valuable time for personnel evacuation and rescue.​ The 240mm² cross-sectional area enables it to have a large current-carrying capacity, making it suitable for places with extremely high fire safety requirements such as high-rise buildings, large shopping malls, hospitals, subways, and nuclear power plants. In the main distribution lines of these places, the cable can ensure the temporary stable operation of the power system in case of fire, and supply power to key facilities such as emergency lighting and fire-fighting equipment. At the same time, its excellent mechanical properties and environmental resistance can also adapt to complex laying environments.​ With the characteristics of flame retardancy, halogen-free and low smoke, high insulation, etc., the cable has become the core choice for power transmission in high safety level places, providing a strong guarantee for the safety of life and property.
