High Quality Three Phase Epoxy Resin Cast Dry Type Transformer for Indoor Power Distribution

Product Overview & Application

The dry-type transformer is a core electrical component designed for safe and efficient voltage transformation in environments where fire safety and environmental protection are paramount. Unlike oil-immersed types, it uses solid insulation materials (typically cast resin) for both insulation and cooling. It is widely applied in urban power grids, commercial centers, hospitals, subways, and industrial manufacturing facilities, ensuring a reliable and secure power supply without the need for fire suppression systems or oil containment.

Key Features & Advanced Technology

1.Fire Safety & Environmental Protection: No combustible insulating oil is used, completely eliminating fire hazards and oil leakage risks. The transformer is self-extinguishing and produces no toxic smoke, making it safe for indoor installation.

2.High Mechanical Strength: The epoxy resin casting process ensures a robust structure. The high-voltage and low-voltage windings are cast into a solid unit, providing excellent resistance to short-circuit electromagnetic forces and preventing winding deformation.

3.Excellent Heat Dissipation & Low Loss: Equipped with high-quality silicon steel cores (or optional amorphous alloy) to significantly reduce no-load and load losses. The advanced cooling duct design ensures uniform heat dissipation and extends operational lifespan.

4.Maintenance-Free Operation: The solid insulation structure is highly resistant to moisture, dust, and pollution. It requires virtually no routine maintenance, drastically reducing operational costs.

5.Customization: We support OEM/ODM services. The transformer can be equipped with intelligent temperature controllers, cooling fans (AN/AF), and IP20/IP23 enclosures. Voltage ratios and capacities can be fully customized based on your project requirements.
