strain insulator

Tightening insulators are a special type of insulation control that can play a dual role in supporting conductors and preventing current grounding in overhead transmission lines.
Tightening insulators are currently widely used, and their installation methods include wedge clamp installation method and pre twisted installation method. The JH10-90 type tension insulator has a dual safety function. Even if the insulation layer is damaged due to overload, the tension insulator ensures the continuity of the cable and prevents pole tilting and falling accidents. The generation of tension insulators fills the gap in the field of 10kV transmission lines at home and abroad where there is no dedicated tension insulator. It can withstand a voltage of 42kV and allow a tension of 90kN. Moreover, when the tension of the cable exceeds the allowable tension, the insulation layer is damaged
