EPGC308 Epoxy Glass Laminate is a high-performance electrical insulation material designed for demanding mechanical, thermal and electrical applications. Recognized by its distinctive green, agate-like appearance, EPGC308 combines high mechanical strength at elevated temperatures, stable electrical performance under high humidity and H-class thermal resistance up to 180°C.

These properties make EPGC308 particularly suitable for electrical equipment operating under high temperature, high humidity and high-voltage conditions.

High Mechanical Strength at Elevated Temperatures

One of the key advantages of EPGC308 is its excellent mechanical strength at elevated temperatures. Compared with conventional epoxy glass laminates, it is designed to maintain reliable mechanical performance when exposed to demanding thermal conditions.

EPGC308 also offers stable electrical insulation performance in humid environments, making it suitable for equipment where both thermal and moisture resistance are important.

With an H-class insulation rating, EPGC308 is suitable for electrical applications requiring operation at temperatures up to approximately 180°C, subject to the specific system design and applicable insulation standards.

Where Is EPGC308 Used?

EPGC308 Epoxy Glass Laminate is widely suited to electrical insulation structures where high mechanical strength, heat resistance and reliable electrical insulation are required.

A typical application is traction motors used in high-speed trains, electric multiple units and railway locomotives. In these demanding environments, insulation components can be exposed to elevated temperatures, vibration, moisture and electrical stress.

EPGC308 can be machined into various insulation components used in traction motors and other electrical equipment, helping provide reliable insulation and structural support under demanding operating conditions.

It is also suitable for H-class motors, transformers, carbon brush holders and other electrical insulation structural components.

EPGC308 Compared with EPGC203

EPGC308 offers performance characteristics similar to EPGC203 in several areas, including electrical insulation and mechanical performance, while providing improved heat resistance for applications requiring a higher thermal class.

This makes EPGC308 a suitable choice when the application requires both strong mechanical performance and stable insulation properties under elevated-temperature conditions.

Available Thicknesses and Custom Solutions

EPGC308 Epoxy Glass Laminate is available in standard thicknesses from approximately 0.5 mm to 50 mm. Customized thicknesses and machined components can also be produced according to customer drawings, dimensions and application requirements.

Depending on the application, the material can be supplied as laminated sheets or processed into customized insulation parts for motors, transformers, railway equipment and other electrical systems.

EPGC308 for High-Temperature Electrical Insulation

When electrical equipment operates under a combination of high temperature, high humidity, mechanical stress and electrical load, the insulation material must provide more than basic dielectric performance.

EPGC308 combines H-class thermal resistance, high-temperature mechanical strength and stable electrical insulation under humid conditions, making it a practical solution for demanding electrical and railway applications.
