八、耐张线夹STRAIN CLAMP
耐张线夹主要用于架空电力线路或变电站，固定导线和避雷线，并通过联结金具与耐张绝缘子相连，或将避雷线与杆塔相连。接结构和安装方法不同分为螺栓型，压缩型两大类，压缩型又分液压和爆压两种。
This kind of product is mainly used in standing electric power line or substation,stationary conduction line and lightning conductor,and also be used in jointing the strain insulator by join hardware or jointing the lightning conductor with the perch.They can be divided into two major varieties,which are bolt type and compression type according to the different structure and installation method.But the compression type is also divided to hydraulic type and detonation type.
