1. Product Usage: This product is suitable for power lines with a rated voltage (U0/U) of 0.6/1kv to 1kv/3KV, for the purpose of power transmission and distribution.
2. Product standard: GB12706-91 rated voltage 3KV and below copper core, aluminum core plastic insulated power cables.
3. Product usage characteristics: (1) When laying cables in environments with temperatures not lower than 0 ℃, there is no need for pre heating. The laying height of cables is not limited. (2) The long-term allowable working temperature of the cable core shall not exceed the following regulations: for cables with an outer protective layer of polyvinyl chloride sheath, the temperature shall be 90 ℃; The outer protective layer of the cable is made of polyethylene sheath, and the temperature is 80 ℃. (3) When the wire core is short circuited (for a maximum of 5 seconds), the temperature shall not exceed 250 ℃. (4) The minimum bending radius for cable laying is specified as follows: single core cable: 20 (d+D) ± 5%; Three core cable: 15 (d+D) ± 5%. In the formula: D is the actual outer diameter of the cable, and d is the actual outer diameter of the conductor.
