Wedge-type Tension Clamps Are Less Prone To Partial Discharge Under Normal Conditions.

Due to its structural design and material selection, the dead clamp exhibits a low rate of partial discharge during operation. Based on the design principle of dead end clamp overhead line, the wedge structure transmits mechanical tension to the hardware body through the geometric engagement between the wire and the inner cavity of dead end clamp with eye hook, while forming a stable contact interface in the contact area. This geometric engagement reduces the uneven distribution of the interface electric field, thereby decreasing the generation of localized high electric field intensity, which is one of the main factors inducing partial discharge.

From the perspective of electrical insulation, the spacing and insulation characteristics between dead end loop clamp and the conductor insulation layer can provide the necessary electrical isolation. This isolation helps suppress the occurrence of electric field tip effects, thus significantly reducing the probability of partial discharge under normal operating voltage.
