Transformer Insulation Film

Transformer Insulation Film is a high-performance electrical insulation film specifically engineered for transformer manufacturing applications. Typically made from premium biaxially oriented polyester (PET) resin, it features excellent dielectric strength, outstanding electrical insulation performance, good thermal stability and superior dimensional stability. This transformer insulation film also offers good resistance to transformer oil, chemicals and moisture, maintaining reliable insulation performance under long-term operation and temperature fluctuations. It is widely used for layer insulation, winding insulation, inter-turn insulation and barrier insulation in oil-immersed transformers and dry-type transformers. We provide various thickness and width specifications, and support customization of roll length and surface treatment to meet the specific insulation requirements of different transformer models and production processes.
