The Insulating Protective Function Of Insulator Covers In Power Transmission Systems

When operating in complex environments, exposed wires or joints may appear in some areas of tension insulator. These exposed areas are susceptible to external environmental influences, leading to local electric field distortion and partial discharge. Therefore, an insulating cover is installed at the dead end insulators mounting location to cover the exposed points and form a physical barrier. The cover is made of high-performance insulating material, conforms to the shape of dead end suspension insulators, and, when combined with the polymer deadend insulator surface, forms a continuous insulating layer, isolating potential external contact sources from the boundary.
