Application: Recently,along with the widely use of composite insulators in overhead power transmission line,especially the by-pass jumper chain of tension pole tower.It is necessary to add counter weight to improve the windproof deflection ability of power transmission line for the wind deflection discharging accident caused by composite insulators with light weight and bad windproof deflection ability.There are design defects in structure of current counter weight,not only the installation and removal process is complicated,which increases the work strength for worker,but also the safe accident will be easily caused for the round structure,as it cannot be easily strapped,passed up and down and fall out.
