Improper Installation Of Wedge-shaped Tension Clamps May Induce Discharge Channels.

The installation location of dead and clamp and its relative arrangement with surrounding components have a significant impact on electrical performance. Proximity to grounding components alters the local electric field distribution, creating low-impedance paths and abnormal current paths between the conductor and ground. Such electrical paths are more prone to arcing in high-humidity, salt-spray environments, potentially leading to partial discharge accumulation and equipment aging.

For overhead insulated lines, the distance between insulator dead clamp and the grounding electrode is a crucial design parameter when the conductor is taut and fixed to the support structure. If the distance is insufficient, it may cause a deflection path to form on the surface of the insulator or near dead end clamp overhead line, which may lead to leakage in the rainy season or in coastal areas with salt spray. Over time, this leakage path can also lead to insulator breakdown or corrosion damage to accessory components, affecting the stability and safety of the power supply system.
