Arc Path Phenomenon Caused By Abnormal Tip Of Wedge-shaped Tension Clamp

Under the operating environment of high-voltage lines, a significant electric field exists around the conductors. When the geometry of dead end clamp with eye hook exhibits irregular, sharp points, the local electric field gradient at that location will be distorted. This may induce ionization of the surrounding medium, guiding the formation of an arc channel. The sharp point effect is one of the electrical phenomena that must be considered in the design of high-voltage equipment. In the insulation configuration and hardware layout of power systems, any protruding sharp part can potentially become a source of partial discharge.

dead end loop clamp Under conditions of poor assembly or slight deformation caused by stress, this abnormal sharp point shape is more likely to occur in the actual environment. Overhead lines have strict design considerations for electric field balance. dead end tension clamp, as a mechanical connection between the conductor and the tension insulator, also participates in the electric field distribution. When unexpected geometric protrusions appear on the surface of fiber optic dead end clamp, it will affect the insulation span and the electric field distribution. With changes in climatic conditions or corrosion accumulation caused by long-term operation, the local electric field changes in this sharp point area may further promote ionization.
