Hieavy Current Bushing

High Current Bushing is mainly used for high voltage electrical equipment that needs to carry heavy current, such as Generator step-up (GSU) transformers, HVDC converter transformers, arc furnace transformers and High-current bus connections in gas-insulated switchgear. And its core role is to insulate and conduct current to ensure the safe transmission of the current.
