大跨越工程中使用光纤复合地线(OPGW)的研究

Study on applying OPGW(Optical Ground Wire )in river-crossing project

根据输电线路大跨越工程档距大、悬点高的特点 ,比较了光纤复合地线 (OPGW )各种结构性能 ,从OPGW制造、光纤受力、配套金具。

According to the characteristics of the river-crossing project of power transmission lines,namely the large span and the high suspension point,the performance of OPGW of various structures was compared with that of three other optical wires.The feasibility of applying OPGW in the river-crossing project was expatiated and demonstrated from the aspects of manufacturing,the stress bared,the supporting hardware and vibration prevention measures of the OPGW.
