Structural Features of Dry-Type Transformers

Safety, fireproof, pollution-free, and ready for direct operation in load centers.

2. Featuring advanced domestic technology, high mechanical strength, strong short-circuit resistance, minimal partial discharge, excellent thermal stability, high reliability, and long service life.

3. Low-loss, low-noise, significant energy-saving effects, and maintenance-free.

4. Excellent heat dissipation performance, strong overload capacity; can increase capacity operation under forced air cooling.

5. Excellent moisture resistance, suitable for operation in high humidity and other harsh environments.

6. The dry-type transformer is equipped with a comprehensive temperature detection and protection system. Utilizing an intelligent signal temperature control system, it can automatically detect and display the working temperature of each phase winding, automatically start and stop fans, and has features such as alarm and circuit breaker settings.

7. Compact, lightweight, space-saving, and low in installation costs.

Core iron

Utilizing cold-rolled grain-oriented silicon steel sheets, the core silicon steel sheets are fitted with 45-degree full diagonal joints, allowing the magnetic flux to pass through along the joint direction of the silicon steel sheets.

Winding Configuration

Twisting

Epoxy resin filled with quartz sand casting.

Glass fiber reinforced epoxy resin casting (i.e., thin insulating structure)

④ Multi-filament glass fiber wrapped with epoxy resin (usually in a 3-ply configuration, as it effectively prevents the resin from cracking during casting, enhancing the equipment's reliability).

High-voltage winding

Generally, multi-layered cylindrical or segmented structures are employed.
