Electrical Insulation Precompressed Pressboard is a high-density, high-mechanical-strength insulation material widely used in transformers, reactors, bushings, switchgears and other high-voltage electrical equipment. It features good insulation performance, oil resistance, heat resistance, mechanical strength and processing stability, and plays a key role in electrical isolation, structural support and end fixing. To ensure its insulation performance, mechanical integrity and service safety in equipment, the following precautions must be strictly observed during storage, handling, processing, installation and operation.

In high‑speed motors, large transformers, surge arresters and high‑reliability inductors, the choice of binding and insulation material directly determines equipment stability, service life and operational safety. For manufacturers and maintenance engineers worldwide, Hanyao Unidirectional Glass Fiber Tapes have become the trusted preferred solution, combining superior mechanical strength, reliable insulation performance, customizable grades and consistent factory quality.
