Name:
Cross-linked polyethylene insulated power cable
Description:
Product Application: This product is suitable for electric power transmission lines with rated voltage (U0/U) ranging from 3.6/6 to 26/35KV, for the purpose of energy transmission and distribution.
2. Product Standard: GB12706-91 rated voltage 35KV and below copper-core, aluminum-core plastic insulated power cables.
3. Product Characteristics: (1) No preheating is required when laying the cable under environmental temperatures not below 0℃. The laying drop of the cable is unrestricted. (2) The long-term allowable working temperature of the cable cores must not exceed the following specifications: 90℃ for cables with a polyvinyl chloride sheath; 80℃ for cables with a polyethylene sheath. (3) The temperature must not exceed 250℃ during core short-circuit conditions (lasting longer than 5 seconds). (4) The minimum bending radius for cable laying is as follows: Single-core cable: 20(d+D)±5%; Three-core cable: 15(d+D)±5%. Where: D is the actual outer diameter of the cable, d is the actual outer diameter of the conductor.
