10kv overhead insulated cables under

タイトルまたは説明

First, cable performance standards name, number and use of 1, Rated voltage 1KV and below overhead insulated cables GB*******0 2, rated voltage of *0KV, *5KV overhead insulated cable GB*******3 3, Uses: mainly used in urban network, rural power grids, namely, overhead insulated cables instead of bare overhead line as the city of overhead transmission lines, the lines in the vicinity of trees or buildings do not need cut or removed, and the safe and reliable, thus protect the urban environment. Third, using the characteristics of cable A, cable laying temperature of not lower than **0 ℃. 2, the long-term to allow the maximum conductor operating temperature: cross-linked polyethylene insulated cables *0 ℃, high-density polyethylene insulated cables *5 ℃, PVC, polyethylene insulated cables *0 ℃. 3, cable bend radius: single-core cable: not less than *0 (D + d) ± 5% mm Multi-core cable: not less than *5 (D + d) ± 5% mm D - cable diameter, d - diameter conductor
