The silicone rubber bushing for Transformer is a crucial component that helps to protect the internal components of the transformer from damage and ensures efficient operation. It typically consists of multiple layers of material, such as paper, pressboard, or plastic, which are wound around the transformer coils. This transformer insulation sheath helps to prevent electrical breakdown, overheating, and corrosion, which can lead to potential safety hazards and reduce the lifespan of the transformer. Additionally, the insulation sheath also helps to contain and control oil leakage, which is commonly used as a coolant and insulating fluid in transformers. Therefore, regular inspection and maintenance of the insulation sheath is essential to ensure the safe and reliable operation of the transformer.
