Inside various electrical equipment such as transformers, motors, generators, and capacitors, besides the obvious components like copper wires, iron cores, and casings, there is a seemingly ordinary yet crucial material—composite paper.
In modern household appliances and industrial equipment, motors are core power components, and their operational stability is directly related to the lifespan and safety of the entire device.
As a high-performance polymer material, polyester film is widely used in a variety of high-tech fields, including electrical insulation, food packaging, new energy, magnetic recording, and optical displays.
At the heart of power equipment, insulation materials silently yet crucially safeguard safety. They isolate high-voltage currents, prevent energy surges, and ensure stable operation.
In modern high-frequency power electronics systems, efficient energy conversion and stable transmission rely on the electrical performance of each material component.
Whether internal fiber and external rubber sleeves effectively block current leakage and ensure safe operation in high-voltage environments is a key question for their suitability as electrical insulation materials in critical applications.
