Transformer insulation sheath is mainly used for insulation protection of transformers. The insulation layer of transformers is easily affected by harsh environments such as high temperature, humidity, and pollution during use, thereby shortening the service life and reliability of the equipment. The function of transformer insulation sheath is to protect the insulation layer of the transformer and prevent it from being affected by these factors.

The performance of transformer insulation sheath mainly includes heat resistance, arc resistance, mechanical performance, voltage resistance, and chemical corrosion resistance. Among them, heat resistance is one of the most important properties of transformer insulation sheaths, because transformers generate a large amount of heat during operation, so they need to have high heat resistance performance. The product has a lifespan of up to 50 years. The transformer sheath is made of synthetic silicone rubber vulcanized at high temperature, which never deforms, has high temperature toughness, and is tear resistant. Has good insulation performance, insulation strength greater than 20KV/mm, insulation resistance greater than 10. The product design is reasonable and easy to install. The buckle structure is easy to disassemble and reuse during maintenance.

The function of transformer sheath: 1. A good transformer sheath is the most basic and reliable means to ensure the safe operation of transformers and prevent personal electric shock accidents. 2. Prevent short circuits between phases caused by overlapping foreign objects such as branches or crawling of small animals. The fundamental function of a transformer sheath is insulation, which prevents external objects and people from directly coming into contact with the transformer. Insulation refers to holding or isolating some charged objects with non-conductive objects, thereby achieving a protective effect and avoiding electric shock, which is a safety measure.
