High-voltage Disconnect Switch Design To Reduce The Impact Of Rainwater
Date: | Read: 15
High Voltage Disconnect Switch often faces natural conditions such as wind and rain. If the switch assembly consists of exposed metal or simple plastic supports, rainwater can cause surface dampness and create conductive paths, affecting insulation.
Porcelain-skirt-shaped insulators, through their outward-flaring skirt structure, physically separate water droplets from the metal contacts or conductive parts. Even in rainfall, water preferentially adheres to the edge of the skirt and slides off, rarely accumulating at the metal contact points or insulation paths. This minimizes surface leakage distance, maintaining air gaps and insulation performance.
