Providing a secure and dependable connection between the transformer and the external electrical system, transformer bushing parts are crucial sections of transformers. High-quality materials like porcelain, glass, and metal are frequently used to make bushing parts, which are meant to endure the demanding operating conditions of a transformer.
Here is a list of some of the most common transformer bushing parts:
Insulator: The essential part of a bushing is the insulator, which acts as an electrical insulator between the conductor and the transformer tank. Typically, insulators are constructed of glass, porcelain, or epoxy resin.
Conductor: The metal tube or rod that transmits the electrical current through the bushing is the conductor. Typically, conductors are constructed of copper or aluminium.
Flange: The metal plate known as the flange fastens the bushing to the transformer tank. Stainless steel or steel are frequently used to make flanges.
Gasket: Oil cannot escape from the bushing thanks to the gasket's seal. Typically, silicone or rubber are used to make gaskets.
Hardware: The conductor is connected to the external electrical system and the bushing is fastened to the transformer tank using hardware like nuts, bolts, and washers.
To fulfil the requirements of various transformer applications, transformer bushing parts are offered in a range of sizes and designs. Transformer bushings come in a variety of popular designs, such as:
Oil-filled bushings: The most popular kind of bushing used in transformers is oil-filled bushing. Oil-filled bushings are the best choice for use in high-voltage applications because they offer excellent insulation and cooling.
Dry bushings: In transformers where oil is not preferred, such as in indoor transformers or transformers situated in environmentally sensitive areas, dry bushings are employed. Various insulation materials, including epoxy resin or gas, are used in dry bushings.
Condenser bushings: High-voltage transformers employ condenser bushings to enhance voltage distribution and lessen corona. A capacitor element that is attached to the conductor is found in condenser bushings.
For transformers to operate safely and reliably, transformer bushing components are essential. Transformer bushing components need to be frequently inspected and maintained to make sure they are in good shape and defect-free.
Here are some additional details about transformer bushing parts:
Insulators: Since they provide electrical insulation between the conductor and the transformer tank, insulators are the most important part of a transformer bushing. High voltages, currents, and temperatures must not damage insulators. They also need to be resistant to chemicals, dampness, and other environmental elements.
Conductors: Heavy currents must be able to flow through conductors without overheating. They must also be corrosion-resistant. Transformer bushing conductors are typically made of copper, though aluminium is also used.
Flanges: The conductor and the transformer tank must exert forces on the flanges, which must be sturdy enough to withstand them. In order to stop oil from leaking out of the bushing, they must also be sealed.
Gaskets: Even when exposed to extreme heat and pressure, gaskets must be able to tightly seal the bushing. Additionally, they must be resistant to chemicals and oil.
Hardware: Hardware needs to be sturdy enough to withstand the forces produced by the transformer tank and bushing. Additionally, corrosion resistance is required.
Numerous businesses all over the world produce transformer bushing parts. When buying transformer bushing components, it's critical to pick a trustworthy manufacturer to guarantee that they adhere to the strict specifications needed for this application.
