The wedge-shaped insulated tensile clamp is suitable for fixing or tensioning the overhead insulated conductor on the end of the overhead insulated conductor or the ends of the tensile section or the ends of the tensile section.

The wedge-shaped structure is proportional to the pulling force of the wire and has the characteristics of self-tightening, and the operation is maintenance-free.

The inner wedge is made of weather-resistant insulation-reinforced engineering plastics, with an AC withstand voltage of 45kV and a pressure of 1 minute without breakdown and flashover.
