Description
| Product characteristics: |
1, product use: This product is applicable to the rated voltage (U0/U) of 3.6/6 to 26/35KV power lines for power transmission and distribution. 2, product standard: GB12706-91 rated voltage 35KV and below copper core, aluminum core plastic insulated power cable. 3, product usage characteristics: (1) cables do not need to be pre heated when the ambient temperature is below 0 C. The laying of cables is not restricted. (2) the long-term allowable working temperature of the cable core shall not exceed the following requirements: the outer sheath is a cable of PVC sleeves of 90 degrees, and the outer sheath is a polyethylene sheath of 80 degrees centigrade. (3) when the core is short circuited (continuous 5S), the temperature should not exceed 250 degrees (4). The small bending radius of cable laying is stipulated as follows: single core cable: 20 (d+D) + 5%; three core cable: 15 (d+D) + 5%. Formula: D is the actual outer diameter of the cable, D is the actual outer diameter of the conductor. 4. Product type, name and scope of use |
