Oil Duct Strips For Oil-Immersed Power Transformers
Technical Specifications of Oil Duct Strips
The Oil Duct Strip is a functional insulating component designed for oil-immersed power transformers. It is made from diamond-dotted paper (DDP) bonded with electrical board strips. It is installed inside the transformer winding oil ducts to guide and control the flow of insulating oil. By optimizing oil circulation paths, the oil duct curtain helps improve cooling efficiency and ensures stable transformer operation.
Manufactured from high-quality insulating materials, the oil duct curtain offers excellent oil resistance, thermal stability, and mechanical strength, making it suitable for long-term operation under harsh electrical and thermal conditions.
