A HV (high voltage) bushing is an electrical insulating component used in transformers to isolate high voltage electrical connections and to provide a pathway for electrical current to flow from the transformer’s windings to the outside circuit.
The HV bushing is typically made of porcelain or composite materials and has a metal conductor running through the center. The metal conductor is typically connected to the high voltage winding inside the transformer, while the exterior of the bushing is connected to the high voltage connection on the outside of the transformer.
HV bushings play an important role in the safety and performance of transformers, as they help to protect against electrical shock and arcing. They also help to prevent electrical power losses and maintain the insulation properties of the transformer.
It is important to periodically inspect and test HV bushings to ensure that they are functioning properly, and to replace them if necessary to maintain the safety and reliability of the transformer.
