What is High Voltage Bushing?
Power transmission and distribution systems use High Voltage Electrical Insulation Bushing to provide safe electrical insulation and mechanical support to the conductor that passes through a grounded barrier, i.e. transformer or switchgear casing. The bushings are intended to withstand high voltages, harsh environments, and mechanical stresses, and provide reliable electrical performance. Designed with the capability to resist electrical breakdown, high-voltage bushings are constructed from materials such as porcelain, epoxy resin, or composite polymers. Their design frequently compels them to have some kind of central conductor surrounded by insulating materials and an external casing, to minimize arcing and improve safety with operations. In humid or polluted environments, the bushing also may present sheds or ribs to increase the creepage distance, reducing the leakage current in the surface of the bushing. Due to their durability and adaptability, they can be used for transformers, circuit breakers, and other high-voltage equipment in industrial and utility on their behalf.
