Abstract

一种耐雷击光纤复合架空地线，包括用不锈钢管作套管的光纤单元及不锈钢套管外绞合的金属线，金属线的结构为钢丝外镀覆锌层。由于本实用新型的不锈钢套管外绞合的金属线的结构为钢丝外镀覆锌层，而锌的比热和熔点较低，在地线受到雷击时所产生的热量容易散发，故镀锌钢丝不易击断，地线就不易损坏。

Description

耐雷击光纤复合架空地线
技术领域
本实用新型涉及一种输电线路的架空地线，尤其是耐雷击光纤复合架空地线。
背景技术
现有输电线路的光纤复合架空地线一般在用不锈钢管作套管的光纤单元外绞合金属线而制成，金属线通常为铝合金线或铝包钢线，这种光纤复合架空地线遇雷击时其外包的铝金属线容易被击断，导致地线损坏。
发明内容
为了克服现有输电线路的光纤复合架空地线的不足，本实用新型提供一种耐雷击光纤复合架空地线，可以提高耐雷击性能，延长光纤复合架空地线的使用寿命。
本实用新型提供的一种耐雷击光纤复合架空地线，包括用不锈钢管作套管的光纤单元及不锈钢套管外绞合的金属线，金属线的结构为钢丝外镀覆锌层。
本实用新型的有益效果是：由于本实用新型的不锈钢套管外绞合的金属线的结构为钢丝外镀覆锌层，而锌的比热和熔点较低，在地线受到雷击时所产生的热量容易散发，故镀锌钢丝不易被击断，地线就不易损坏。
附图说明
图1是本实用新型的横截面示意图。
在图1中，1、金属线，2、不锈钢套管，3、光纤，4、光纤单元，5、钢丝，6、锌层。
具体实施方式
参照图1，将光纤3设在不锈钢套管2内制成光纤单元4，在钢丝5外镀覆锌层6制成金属线1，再在不锈钢套管2外绞合金属线1，即制成本实用新型。
