Cross-linked polyethylene(XLPE) insulated power cables are a common category of cables used in civil engineering, including normal, flame retardant, fire-resistant, and halogen-free low smoke flame retardant. Cross-linked polyethylene insulated power cables are resistant to environmental stress. It also has the characteristics of high mechanical strength, chemical resistance, excellent electrical performance, simple structure, lightweight, and easy to use.
1. Cross-linked polyethylene insulated power cable Application: This product is suitable for power lines with rated voltage (U0/U) of 3.6/6 to 26/35KV. It is used for the transmission and distribution of energy.
2. Cross-linked polyethylene insulated power cable standard: aluminum core plastic insulated power cable, GB12706-91 rated voltage 35KV, and below the copper core.
3. Cross-linked polyethylene insulated power cable use characteristics: (1) No preheating is required when laying the cable at an ambient temperature of not less than 0℃. There is no restriction on cable laying. (2) The long-term allowable working temperature of the cable core shall not exceed the following provisions: 90℃ for cables with PVC sheath. With polyethylene sheath cable for 80 ℃. (3) core short-circuit (maximum duration of 5S), the temperature should not exceed 250 °C. (4) The minimum bending radius when laying the cable is as follows: single-core cable: 20 (d D D) ± 5%. Three-core cable: 15 (d D) ± 5%, in the formula: d is the actual outer diameter of the conductor, D is the actual outer diameter of the cable.
