OPGW光缆主要在500KV 、220KV 、110KV电压等级线路上使用,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:
☆.高压超过110kv的线路,档距较大(一般都在250M以上);
☆.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;
☆.OPGW外层为金属铠装,对高压电蚀及降解无影响;
☆.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; ☆.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。
☆.兼具地线与通信光缆的双重功能,免去了重复架设与维护的巨大费用;
☆.安装在电力架空线杆塔顶部,无需考虑最佳挂点与电腐蚀等因素;
☆.老线路改造过程中,光缆的外径、拉力单重比另一根地线能好地匹配;
☆.传输容量大,通信质量高、可靠性好;
☆.具有优越的机械及电气性能;
☆.安全性能好,使用寿命长,不易遭到破坏性枪击。

Application:
☆.OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines. Its applications are:high pressure over 110kv, with a longer span (usually over 250M);
☆.easy to maintain, easy for line span, its mechanical property can meet a big line span;
☆.outer OPGW is metal armoring, with no influence for high pressure electro-corrosion and degradation;
☆.to construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv;
☆.For OPGW performance index, the more short circuit current, the more need a good conductor to be metal armor, and reduce tension strength, while, if the tension strength is certain, to increase short circuit current capacity, the only way is to enlarge metal section area, resulting in an increased cable Dia and weight, so that security is a question for line pole strength.
Characteristics:
☆.bio-function of ground wire and communication cable, avoid a huge expenditure to re-erect and re-maintain;
☆.erect on top of power overhead line pole, need not to consider its best hanging point, electro-corrosion, and others.
☆.in the process of old line transformation, cable’s outer diameter and tension may be matched better than another ground wire;
☆.big transmission capacity, good and reliable communication;
excellent mechanical and electrical property;
Good security, long lifetime, and invulnerable to gun fire.
