OPGW光缆运用

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。

层绞不锈钢管式光纤复合架空地线规格、结构及相关参数

 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.
