‌Product Introduction
20kV 400kVA dry-type distribution transformer is a power transformer mainly used for voltage conversion and power distribution in distribution systems. ‌

Basic parameters and performance characteristics of dry-type distribution transformers
‌Rated capacity‌: 400kVA, suitable for medium power demand.
‌Voltage level‌: 20kV, suitable for high-voltage distribution systems.
‌Efficiency‌: Dry-type transformers usually have high efficiency and stability, suitable for long-term operation.
‌Insulation material‌: Common insulation materials include epoxy resin and Nomex insulation paper, which have excellent insulation performance and durability‌

Three-phase transformer application scenarios
Dry-type transformers are suitable for places with high environmental requirements, such as commercial centers, hospitals and subways. Since it does not use oil as an insulating medium, it has better environmental protection performance. In addition, dry-type transformers are also suitable for high-rise buildings, modern factories and rural power grids because of their small size, light weight, low loss, easy installation and maintenance.

400kva three-phase dry-type transformer manufacturing process and materials
The core of the dry-type transformer is usually stacked with silicon steel sheets or oriented silicon steel sheets, and the winding uses single-turn or multi-turn cylindrical copper wire. This design makes the transformer smaller and lighter at the same capacity, making it easier to transport and install.

Maintenance and use precautions
Insulation strength: The insulation resistance should be greater than 2MΩ. m.
Oil temperature: The normal oil temperature should not be greater than 60°C.
Cooling medium: The operating temperature should not be higher than 40°C.
Noise: When unloaded, the noise value should not be greater than 85 dB(A).
Overload protection: When the load current is greater than the rated output, an overload protection device must be installed to prevent serious accidents.
