Brand: WEIJI
Capacity: 6.6KV~35KV
Voltage: 30KVA~5000KVA
USES: This product is suitable for important places such as urban power grid, tower block, business center, theater, hospitals, hotel, tunnel, subway, high-speed rail, and airport.
The dry-type transformer is an epoxy resin cast power transformer, unique in that its iron core and windings are not immersed in insulating oil. Its cooling methods mainly include natural air cooling (AN) and forced air cooling (AF). From iron core production to resin casting and assembly, the entire process is self-made by WEIJI.Our dry transformer capacity range from 50-3000KVA,voltage from 6.6kv-35kv.
High voltage coil: Orthogonal self-flow casting process is adopted to ensure insulation performance and structural stability. Low voltage coil: Self-flow casting process with upper and lower ends sealed to improve sealing and mechanical strength. 
Precision casting technology
Core materialAdopting brand-new cold-pressed oriented silicon steel sheet, it has high magnetic permeability and low loss.
Seven-step 45° fully beveled seams improve aesthetics and electromagnetic performance.
Replaces traditional channel steel parts, simplifies structure, facilitates installation, and further enhances product quality.
