Epoxy Casting System

Epoxy casting system is a complete material combination. It is designed for electrical insulation casting. This product includes resin, hardener, and necessary additives. These additives include accelerator, coupling agent, and defoamer. All parts are supplied in exact chemical ratio. This product removes the need for buyers to study hardener ratios and additive amounts. Our R&D team has verified all ratios in the lab. It is available for OEM replacement, aftermarket supply, and bulk orders.

Our epoxy casting system fits many electrical equipment types. It is used in dry-type transformer and reactor overall casting systems. It also suits medium and high voltage transformer insulation encapsulation. Special motors and generator stator insulation systems use it. Power electronic module potting protection systems also use it. Indoor and outdoor insulation part molding systems benefit from it. The table below shows typical equipment matching.

These values help buyers compare systems. They also help engineers set process parameters. The data comes from third-party CMA and SGS reports. Each batch is traceable.

This system supports replacement and custom supply. Buyers often come with a device model, drawing, or performance target. They need a material that matches the original insulation system. We review the voltage level, wall thickness, and curing method. Then we recommend the right grade. The table below shows common replacement scenarios.

This system offers several engineering benefits. It has stable mixed electrical strength at or above 28 kV/mm. It reaches a mixed glass transition temperature above 130°C. It shows mixed flexural strength at or above 120 MPa. It also keeps working time from 40 to 120 minutes at 40°C. These features reduce mixing errors on site. They also improve curing consistency. The system includes a mixed performance test report for each shipment. This report covers electrical strength, flexural strength, and heat distortion temperature.

We control quality at every production step. Each batch goes through four inspection stages. These are incoming material check, process check, finished product check, and shipment check. We test mixed electrical strength, flexural strength, and heat distortion temperature. We also keep samples for traceability. Our factory holds CMA and SGS reports. These reports verify the key values in the specification table. We provide test data for each shipment.

Buyers can use the table below to match the right system.

First, confirm the equipment type and voltage level. Second, check the required insulation thickness and curing method. Third, review the viscosity and working time needs. Fourth, compare electrical strength and heat resistance. Fifth, request a free sample for line testing.
