Live line washing, also known as live line maintenance or hotline washing, is a method used to clean high-voltage power lines while they’re energized. It helps in preventing dirt, pollution, and contaminants from accumulating on the insulators of power lines. By keeping these insulators clean, live line washing ensures efficient electricity transmission, reduces the risk of power outages, and maintains the reliability of the power grid. Additionally, it enhances the safety of workers by allowing maintenance without power interruption.
