Aerial Bundled Cables

The product has a weather-resistant, wear-resistant, high mechanical strength, the line loss characteristics. Widely used in regional power grids that can significantly improve the security and reliability of power grids can be applied to the rated voltage of 35kV and below the electricity network. Polyethylene, PVC insulated cables to allow long-term temperature not exceeding 70 , cross-linked polyethylene insulated cables to allow long-term temperature does not exceed 90 . When short-circuit (5 seconds) polyethylene insulated cables allow the temperature does not exceed 130 , PVC insulated cables less than 160 , cross-linked polyethylene insulated cables does not exceed 250 . Installed around the ambient temperature is not lower than -20 . 0.6/1kV rated voltage cables such as the outer diameter of less than 25mm, while allowing the smallest bend radius of 4 times the cable diameter; such as cable diameter greater than or equal to 25mm, while allowing the smallest bend radius of 6 times the cable diameter. Rated voltage of 10kV or more of the following 35kV multi-core cable, the minimum bend radius should be not less than 15 times the diameter cables and conductors and the outer diameter, single-core cable should be not less than 20 times the diameter cables and conductors and the outer diameter.
