In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it. Bushings are typically made from porcelain, though other insulating … See more All materials carrying an electric charge generate an electric field. When an energized conductor is near a material at earth potential, it can form very high field strengths, especially where the field lines are forced to curve … See more Porcelain insulation The earliest bushing designs use porcelain for both indoor and outdoor applications. Porcelain was originally used due to its properties of being impervious to moisture once sealed by fired glaze, and low manufacturing cost. … See more A bushing must be designed to withstand the electrical field strength produced in the insulation, when any earthed material is present. As the strength of the electrical field increases, leakage paths may develop within the insulation. If the energy of the leakage path … See more Bushings sometimes fail due to partial discharge. This is sometimes due to the slow and progressive degradation of the insulation over … See more
