Product Description

1. Product Standard: GB/T14049-2008
2. Application: This product is suitable for copper core, aluminum core, and aluminum alloy core weather-resistant overhead cables insulated with high-density polyethylene and cross-linked polyethylene for AC rated voltage of 10kV and below overhead power lines.
3. Usage Characteristics
Cable conductor long-term allowable operating temperature: High-density polyethylene insulation should not exceed 75℃; cross-linked polyethylene insulation should not exceed 90℃.
The ambient temperature for cable laying should not be lower than -20℃.
The allowable bending radius of the cable should not be less than the diameter of the cylindrical body used in the cable bending test.

Note:
1. Among them, K is the load-bearing stranded wire. According to engineering design needs, the specified cross-section can be selected to match the corresponding conductor cross-section. If a larger tower span uses an additional load-bearing cable, this load-bearing cable is not included in the cable structure.
2. (A) indicates steel load-bearing stranded wire, (B) indicates aluminum alloy load-bearing stranded wire.
