Electrical Grade Epoxy Casting

We are a manufacturer that specializes in insulation materials for medium and high voltage power equipment. In power equipment manufacturing, the electrical performance of insulation materials directly determines the reliability and service life of the equipment. We formulated our electrical grade epoxy casting specifically to meet the demanding requirements of transformers, switchgear, and other high-voltage applications. Our product provides excellent insulation protection that you can count on.

Our electrical grade epoxy casting uses high-purity raw materials and a precisely balanced curing system. This delivers extremely high volume resistivity and dielectric strength. Our factory operates 6 reaction vessels, 3 drying ovens, 3 grinding mills, and 3 dispersant containers. We control every stage from raw material grinding to finished product shipment. Our product has been used by multiple transformer manufacturers in Guilin for over four years. Key indicators like breakdown voltage and dielectric strength have remained stable throughout this period. All products have passed SGS testing and CMA certification. We also hold three system certifications for quality management.
