High-Performance Electrical Insulating Epoxy Resin for Transformer Casting (80℃ Cure)

Our Electrical Insulating Epoxy Resin is a premium insulating material engineered for transformer casting applications that demand reliable electrical performance and mechanical strength. Designed for use in high-voltage transformers, current transformers (CT), and dry-type transformers, this advanced resin system cures at 80℃, forming a robust thermoset matrix that delivers exceptional insulation and dimensional stability.

Manufactured by Jiangte Insulation Composite Co., Ltd., this Electrical Insulating Epoxy Resin is ideal for electrical engineers, transformer manufacturers, and production facilities seeking insulation resins with high dielectric resistance, chemical resistance, and mechanical properties that stand up to demanding environments in Southeast Asia, the Middle East, and South America.

Jiangte’s Electrical Insulating Epoxy Resin offers a well-balanced set of electrical, thermal, and mechanical properties designed for superior performance in electrical insulation and transformer casting:

This Electrical Insulating Epoxy Resin exhibits high volume resistivity (up to 10¹⁴ Ω·cm) and outstanding dielectric resistance, helping to prevent leakage currents and maintain insulation integrity under high voltage conditions.

With an optimal curing temperature of 80℃, the resin system hardens into a stable thermoset that resists thermal stress and degradation. The result is long-lasting insulation performance, even in high operating temperatures.

This insulation resin delivers high compressive strength (up to 100 MPa) and tensile strength (approximately 80 MPa), giving structural support and protection to transformer windings, core components, and electronic parts.

Our Electrical Insulating Epoxy Resin provides excellent resistance to moisture, chemical exposure, and aging, making it suitable for use in challenging climatic conditions — especially in tropical and coastal regions.

This resin system is formulated for efficient casting processes, including vacuum casting, and offers a manageable curing cycle of around 24 hours, which improves production throughput while preserving quality.
