OPGW光缆,Optical Fiber Composite Overhead Ground Wire(光纤复合架空地线)OPGW光缆,Optical Fiber Composite Overhead Ground Wire(光纤复合架空地线)·Description
OPGW光缆主要在500KV 、220KV 、110KV电压等线路上使用,受线路停电、安全等因素影响,多在新建线路上应用。
OPGW的适用特点是:
(1)高压超过110kv的线路,档距较大(一般都在250M以上);
(2)易于维护,对于线路跨越问题易解决,其机械特性可满足线路大跨越;
(3)OPGW外层为金属铠装,对高压电蚀及降解无影响;
(4)OPGW在施工时必须停电,停电损失较大,所以在新建110kv以上高压线路中应该使用OPGW;
(5)OPGW的性能指标中,短路电流越大,越需要用良导体做铠装,则相应降低了抗拉强度,而在抗拉强度一定的情况下,要提高短路电流容量,只有增大金属截面积,从而导致缆径和缆重增加,这样就对线路杆塔强度提出了安全问题。

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath.
