Epoxy Resins
Application and Structural Characteristics
Epoxy resins are widely used as insulation and encapsulation materials in electrical and power equipment, primarily for electrical insulation, structural fixation, and environmental protection of electrical components.
They are suitable for applications requiring reliable insulation performance, mechanical strength, and long-term operational stability, and are commonly used in transformers, switchgear, and related electrical systems.
In practical applications, epoxy resins can be adapted to various manufacturing and encapsulation processes to meet different equipment structures and operating conditions. By selecting appropriate resin systems and process methods, both insulation performance and overall structural stability can be effectively ensured.
