Utilizes natural air cooling (AN) or forced air cooling (AF). AF mode can increase capacity.

Environmentally Friendly

Contains no oil, making it more environmentally friendly, especially suitable for locations with strict environmental requirements.

Safety

Possesses excellent flame-retardant and self-extinguishing fireproof properties, strong short-circuit resistance, and high reliability.

Maintenance

Minimal maintenance required; can be equipped with a comprehensive temperature monitoring and protection system.

Environmental Conditions

-45°C ~ +40°C, relative humidity <70%
Altitude: not exceeding 2500 meters
Avoid exposure to rain, moisture, high temperature, high heat, or direct sunlight. Ventilation openings should be at least 40cm away from surrounding objects
Prevent operation in environments with corrosive liquids, gases, dust, conductive fibers, or metal shavings
Prevent operation in environments with vibration or electromagnetic interference
Avoid long-term inverted storage and transportation, and avoid strong impacts

Typical Applications

High-rise buildings, commercial centers, hospitals, airports, docks, subways, etc.
Factory workshops
Local lighting
Places with special environmental requirements, such as museums, tunnels, laboratories, etc.

Frequently Asked Questions

What is a dry type transformer and how does it differ from an oil-filled transformer?

A dry type transformer uses air as the cooling medium instead of insulating oil. Unlike oil-filled transformers, it eliminates risks of fire, explosion, and oil leakage, making it safer and more suitable for indoor or environmentally sensitive installations.

What cooling methods are available for dry type transformers?

Dry type transformers support natural air cooling (AN) and forced air cooling (AF). AF mode uses fans to actively circulate air, which can increase the transformer's rated capacity compared to AN mode.

What are the recommended installation environment conditions?

The transformer should be installed in environments with temperatures between -45°C and +40°C, relative humidity below 70%, and at altitudes not exceeding 2500 meters. It should be kept away from rain, direct sunlight, corrosive substances, and sources of vibration.

Where are dry type transformers typically used?

They are widely used in high-rise buildings, commercial centers, hospitals, airports, subways, factory workshops, and locations with strict environmental requirements such as museums and laboratories.

How much maintenance does a dry type transformer require?

Dry type transformers require minimal routine maintenance. They can be equipped with a comprehensive temperature monitoring and protection system to ensure safe and reliable long-term operation.

Are dry type transformers safe for use in fire-sensitive environments?

Yes. Dry type transformers feature excellent flame-retardant and self-extinguishing fireproof properties, making them a reliable choice for fire-sensitive locations such as hospitals and underground facilities.
