Dry Type Distribution Transformer

kVA capacity range: ≤5000KVA
Voltage range: ≤20kV
Compliant with IEC standards
Customizable solutions available based on customer requirements.

Product Description:

The transformer utilizes the BWDK series signal temperature gauge. The temperature sensing element is embedded in the upper part of the low-voltage winding, enabling automatic detection and display of the operating temperature of the phase winding. It is equipped with over-temperature alarm and trip functions.

insulation rated at Class F. It is wound on a dedicated low-voltage foil winding machine. The foil winding design effectively addresses issues commonly encountered in products with low voltage and high current windings, such as high short-circuit stress, imbalanced turns, poor heat dissipation, large helix angles, and unstable manual welding quality. Additionally, our company employs resin sealing, curing, moisture-proofing, and anti-contamination measures at the ends of the windings, while the copper busbars are automatically welded using argon arc welding.

Features:

1.Safe, flame retardant, non-polluting, can be directly installed at the load center.

 

2.Maintenance-free, easy installation, low integrated operational costs.

 

3.Excellent moisture resistance, capable of operating normally under 100% humidity.

 

4.Low losses, low partial discharge, low noise, strong cooling capacity, can operate at 150% rated load under forced air cooling conditions.

 

5.Equipped with a comprehensive temperature protection control system, providing reliable assurance for the safe operation of the transformer.

 

6.High reliability. Based on operational studies of deployed products, the reliability indicators of the product have reached international advanced levels.
