OPPC光纤复合相线的应用与探讨

Optical Phase Conductor Application and Discussion

在35-110kV输电线路上架设ADSS或OPGW架空光缆时,原有杆塔需重新加固,而且部分35kV线路本身就没有架空地线,无法架设OPGW光缆。架设ADSS光缆一方面成本较高,另一方面由于弹性模量及热膨胀系数的差异导致ADSS光缆与导线弧垂应力曲线的不一致,且电腐蚀现象严重,维护、检修单位职责不清。本文通过对OPPC光纤复合导线的应用探讨,以解决上述问题。

erects ADSS or the OPGW overhead fiber-optic cable when the 35-110kV transmission line, the original pole tower must reinforce, moreover part 35kV line itself does not have the overhead ground wire, is unable to erect the OPGW optical cable. On the one hand erects the ADSS optical cable the cost to be high, on the other hand because the elasticity coefficient and the thermal-expansion coefficient difference causes the ADSS optical cable with to lead the terminal assembly to hang the curve of pressure and re...
