What is the function of high voltage bushing?

The function of high voltage bushing is to provide electrical insulation and mechanical support to the high-voltage conductor that connects the transformer winding to the outside world. High voltage bushings are used in transformers, circuit breakers, and other electrical equipment that operate at high voltage levels.

The high voltage bushing is designed to withstand the high electrical stresses that occur in high-voltage applications. It is typically made of high-quality insulating material, such as porcelain, epoxy resin, or silicone rubber, and is designed to provide a strong barrier between the high-voltage conductor and the ground or other conductive surfaces.

In addition to providing electrical insulation, high voltage bushings are also designed to provide mechanical support to the high-voltage conductor. They help to maintain the alignment of the conductor and prevent it from moving or vibrating during operation. This is important because any movement or vibration can cause mechanical stresses on the conductor, which can lead to damage or failure.

High voltage bushings also provide a means for connecting the high-voltage conductor to the outside world. They are typically designed to be connected to other electrical equipment, such as a circuit breaker or a transformer bushing connector, and are often equipped with flanges or other mounting features to facilitate installation.

Overall, the function of high voltage bushing is to provide a safe and reliable means of transmitting high-voltage electrical power between the transformer winding and the outside world, while also providing mechanical support and insulation to the high-voltage conductor.
