ANSI Transformer Bushings

Transformer bushing is an essential component used to protect the windings of a transformer. It is typically positioned between the transformer windings and the casing, serving insulation and sealing purposes. Transformer bushings are commonly made of insulation materials such as rubber, silicone rubber, or insulation paper. Their primary functions include:

1. Insulation Protection: Transformer bushings effectively shield the transformer windings from external environmental influences, preventing current leakage and winding short circuits.

2. Waterproof Sealing: Transformer bushings prevent moisture and dampness from infiltrating the interior of the transformer, safeguarding the insulation materials from damage.

3. High Temperature Resistance: As transformers may generate high temperatures during operation, transformer bushings typically require excellent resistance to high temperatures to ensure they remain undistorted or aged under high-temperature conditions.

4. Corrosion Resistance: Some transformer bushings also feature corrosion resistance properties, capable of resisting the corrosion of chemicals and other corrosive media.

5. Mechanical Protection: In addition to providing insulation protection, transformer bushings can offer a certain degree of mechanical protection, shielding windings from external physical damage.

In summary, transformer bushings play a crucial role in the safe operation of transformers and the protection of windings.
