Mismatch Between The Size Of The Wedge-shaped Tension Clamp And The Conductor May Induce A Discharge Path.

Standard fixed dead end clamp specifies clear design conventions for conductor diameter matching. For example, the geometric radius of curvature of the lead groove should be proportionally matched to the conductor size. Typically, the radius of curvature is required to be no less than a certain multiple of the wire diameter; otherwise, it will affect the contact pattern between the dead end clamp and the conductor.

When the size of the ab cable dead end clamp is inconsistent with the connected wire, the shape of the contact surface between the device and the wire changes, which will cause uneven distribution of local electric field. The size mismatch of abc dead end clamp can cause electric field intensity concentration at the junction, which can trigger ionization conditions near the winding in advance, posing a potential threat to the static electric field stability of the insulation system.
