Polyester fiber woven tape is a flexible tape-like material made of high-strength polyester fiber through a weaving process. It is often used for binding and insulating protection of electrical equipment. It is widely used in electrical equipment such as transformers, motors, cables, etc. due to its good mechanical properties, heat resistance and electrical insulation properties.
Functional functions of polyester fiber woven belts
Insulation protection: Effectively prevent short circuits and leakage of electrical equipment and improve equipment safety.
Mechanical fixing: used to fix transformer windings, cable assemblies or motor components to ensure stable operation.
High temperature resistant application: Suitable for high temperature environments to prevent material aging or performance degradation.
Moisture-proof performance: low hygroscopicity, maintaining stable performance in humid environments.
