1. Has good high temperature resistance: XLPE insulation uses chemical or physical methods to change the structure of polyethylene molecules into a three-dimensional network structure. The three-dimensional network structure has good heat resistance and can be used in Long-term work at a high temperature of 90 degrees Celsius, the lifespan can be as long as 40 years. 2. It has good insulation performance: the performance of polyethylene not only retains the insulation performance of cross-linked polyethylene, but also has a further improvement in insulation resistance. 3. High mechanical properties: hardness, stiffness, wear resistance and impact resistance have been improved 4. Chemical resistance: XLPE itself has strong acid and alkali resistance and oil resistance 5. Environmental protection: Since the products of cross-linked polyethylene combustion are water and carbon dioxide, the environmental pollution is low, and it meets the requirements of fire safety. 6. The maximum rated temperature of the cable conductor is 90°C, and the maximum temperature of the cable conductor during short circuit (the longest duration does not exceed 5S) does not exceed 250°C.
The working temperature of the YJLV series cable is the rated working temperature of the conductor at 90℃, the short-circuit temperature of the conductor shall not exceed 250℃, and the time shall not exceed 5 seconds. Lay in soil at an ambient temperature of 25°C
