Product Description

Product Description

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.

The voltage range of our high current bushing is 24kV~52kV, with the rated current from 5000A to 35000A. The material of the conductor is copper or aluminum, the price of copper conductor is a little higher than that of aluminum, but it has much better performance.
