GB12666.6 Fire Resistant Cables PVC Insulation PVC Sheath Electrical Wire

This product is suitable for power frequency rated voltage 3.6/6kv ~ 26/35kv power transmission and distribution lines for power distribution.
1. Product use: This product is suitable for power lines with a rated voltage (U0/U) of 3.6/6 to 26/35KV 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 use characteristics: (1) When the cable is laid under the condition that the ambient temperature is not lower than 0 ℃, it is not necessary to pre-heat. Cable laying heights are not restricted. (2) The long-term allowable operating temperature of the cable core shall not exceed the following regulations: 90°C for cables with a polyvinyl chloride sheath on the outer sheath; 80°C for cables with a polyethylene sheath on the outer sheath. (3) When the wire core is short-circuited (the longest duration is 5S), the temperature shall not exceed 250°C (4) The minimum bending radius when laying the cable is specified 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
