High Voltage Epoxy Resin for Transformers & Switchgear with High Dielectric Strength & Thermal Stability

Epoxy resin is a key material in electrical insulation systems, renowned for its exceptional dielectric properties, thermal stability, and mechanical strength. Formulated with curing agents and additives, it cures into a dense, cross-linked structure that effectively resists electrical breakdown, moisture ingress, and chemical corrosion.

Its low viscosity during processing allows for precise impregnation of complex components such as transformers, switchgear, and high-voltage insulators. Additionally, epoxy's excellent adhesion to metals and ceramics ensures long-term reliability in harsh environments, making it indispensable for modern power transmission and distribution networks.

Enhance interrupting performance with our High Dielectric Strength Curing Agent for MV circuit breaker insulation systems. This engineered hardener creates epoxy composites achieving >30kV/mm dielectric strength - crucial for pole unit encapsulation, arc chute liners, and interphase barriers in 12-40.5kV breakers.

The formulation delivers exceptional arc resistance (>180 seconds) and high comparative tracking index (CTI >600V) to withstand surface discharges during switching operations. When combined with mineral-filled epoxies, it produces robust insulation capable of withstanding mechanical shock from fault closures and thermal stress from interrupting currents.

The material maintains stable capacitance and low dissipation factor across service temperatures (-25°C to +130°C), ensuring reliable grading field distribution. This circuit breaker encapsulation solution provides superior chemical resistance against SF6 byproducts and cleaning solvents while offering unmatched moisture barrier properties (<0.1% WA). Implement this high-performance insulation system for extended maintenance intervals and reduced dielectric failure risks in critical protection equipment.

Contamination of eyes by resin, hardener of casting mix should be treated immediately by flushing with clean, running water for 10 to 15 minutes, a doctor should then be consulted.

Material smeared or splashed on the skin should be dabbed off, and the contaminated area then washed and treated with a cleaning cream. A doctor should be on the event of severe imitation of burns. Contaminated clothing should be changed immediately. Anyone taken ill after inhaling vapors should be moved out of doors immediately, in all case of doubt call for medical assistance.
