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