Epoxy resin cast dry type transformer is an oil-free power distribution transformer.Its high and low voltage coils are fully sealed with epoxy resin via vacuum casting, using air instead of insulating oil for insulation and heat dissipation.During production, windings are poured with epoxy resin under vacuum to remove internal air voids, forming a solid protective insulation layer. Based on electromagnetic induction, it converts voltage safely without liquid flammable medium, unlike oil immersed transformers.
Epoxy resin cast dry type transformers are typically used in environments where the use of oil-filled transformers is not practical or safe, such as in buildings, tunnels, and other confined spaces. They are also preferred in environments where the risk of fire is high, due to their ability to self-extinguish in the event of a fire.They support both indoor and outdoor installation. For indoor applications, they can work without complex enclosures and safely stay near crowds thanks to high safety performance. Outdoors, customized dust-proof and moisture-proof cabinets are available, and they can even run stably in harsh dusty open-pit mine environments.Epoxy resin cast dry type transformers are typically more expensive than oil-filled transformers, but they require less maintenance and have a longer lifespan.
Technical Specifications
Advantages of Epoxy Resin Cast Dry Type Transformer
- Environment-friendly & Safe: Oil-free structure avoids fire risks and pollution, without hazardous substances.
- Low Maintenance: No regular oil inspection or replacement required.
