OPGW光纜運用

OPGW光纜主要在500KV 、220KV 、110KV電壓等線路上使用，受線路停電、安全等因素影響，多在新建線路上應用。

OPGW的適用特點是：

（1）高壓超過110kv的線路，檔距較大（一般都在250M以上）；

（2）易于維護，對于線路跨越問題易解決，其機械特性可滿足線路大跨越；

（3）OPGW外層為金屬鎧裝，對高壓電蝕及降解無影響；

（4）OPGW在施工時必須停電，停電損失較大，所以在新建110kv以上高壓線路中應該使用OPGW；

（5）OPGW的性能指標中，短路電流越大，越需要用良導體做鎧裝，則相應降低了抗拉強度，而在抗拉強度一定的情況下，要提高短路電流容量，只有增大金屬截面積，從而導致纜徑和纜重增加，這樣就對線路桿塔強度提出了安全問題。

5、OPGW光纜參數

層絞不銹鋼管式光纖復合架空地線規格、結構及相關參數

 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.
