Transformer bushings play a vital role in ensuring effortless functioning of the transformers. They promote electricity flow as well as protect the tool from natural elements. Below is a short overview of extensive types and designs of transformer bushings.
Porcelain Bushing
The first transformer bushings type is porcelain bushings. It is one of the most widely used and oldest transformer bushing types. These bushings consist of high-quality porcelain. Porcelain is a material that is known for its mechanical and electrical strength. These bushings are ideal for high-voltage applications.
For this reason, anyone can operate these bushings at a temperature of 900°C. These bushings are used for outdoor applications with mechanical stress and high voltage Contact a transformer bushings manufacturer in India to buy the best quality bushings for any of your needs.
Oil-Filled Bushings
As the name indicates, oil-filled bushings use oil as an insulating element instead of porcelain. These bushings are comparably lighter and smaller than porcelain bushings. Like porcelain bushings, the user can operate oil-filled bushings at greater voltages.
The oil used in these bushings are either syntgetic oil or mineral oil. Both these oils offer better insulation and cooling properties. These bushings are used in circuit breakers, transformers, and other high-voltage devices.
Gas-insulated Bushings
The next category of bushing is gas-insulated bushing. These bushings utilise SF6 or sulfur hexafluoride as an insulating medium. These bushings can function at higher voltages in comparison with oil-filled bushings. The reason behind this is the excellent insulation properties and high dialectic strength of SF6 gas. These bushings are used in switch gears, transformers and other high-voltage elements.
Epoxy Bushings
Epoxy bushing is another effective option in the list which utilises solid insulating component. The insulating component this bushing is made up of epoxy. Epoxy is a component that has enormous moisture and chemical resistance. These bushings are ideal for transformers and switchgears.
Resin-impregnated Paper Bushing
Resin-impregnated paper bushing is a type of dry-type bushing that utilizes solid insulating components. The resin-impregnated paper insulating component of these bushings are eco-friendly and offer good insulation traits. Similar to epoxy bushings, resin-impregnated paper bushings are used for indoor applications like transformers and switchgears.
Hybrid Bushing
Hybrid bushings are a type of bushing that is a successful combination of gas-insulated and oil-filled bushings. These bushings have two part, lower part and upper part. These bushings use SF6 gas as an insulating medium for the upper part and oil as an insulating medium for the lower part.
In comparison to conventional regular oil bushings, hybrid bushings offer better reliability and performance. These bushings are perfect for high-voltage devices like circuit breakers or transformers. Buy excellent-quality hybrid bushings from reputable insulator suppliers in India.
