High-Quality Dry type transformer Exporter, Exporters

The dry-type transformer is a power transformer that does not use insulating oil and dissipates heat through air cooling (natural or forced). It is mainly used in locations requiring fireproofing, explosion-proofing, and moisture protection, such as high-rise buildings, commercial centers, and airports. Compared to oil-immersed transformers, dry-type transformers have advantages such as better fire resistance, reliable operation, convenient maintenance, and strong short-circuit withstand capability..

Product Description

Key Features
Oil-Free Design

The core and windings are not immersed in insulating oil, eliminating the risks of fire, explosion, and oil contamination, allowing direct installation near the load center.

Cooling Method

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
  • Temperature range: -45 ~ +40 (℃), 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 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/transportation and strong impacts
Typical Applications
  • High-rise buildings, commercial centers, hospitals, airports, docks, subways, etc.
  • Factory workshops
  • Local lighting
  • Places with special environmental requirements (museums, tunnels, laboratories, etc.)

Frequently Asked Questions
What is the main advantage of a dry-type transformer over an oil-immersed one?
The main advantage is safety and environmental friendliness. Dry-type transformers use air for cooling instead of oil, eliminating risks of leaks, fire, or explosions, making them ideal for indoor use.
What do AN and AF cooling methods mean?
AN stands for Air Natural cooling, which relies on natural air convection. AF stands for Air Forced cooling, which uses fans to increase airflow and allow the transformer to handle higher loads.
Where should dry-type transformers be installed?
They should be installed in dry, well-ventilated areas away from direct sunlight, corrosive gases, and excessive moisture. They are perfect for high-rise buildings, hospitals, and commercial centers.
Do dry-type transformers require a lot of maintenance?
No, they require minimal maintenance compared to oil-filled units. Regular inspections and cleaning of ventilation paths are usually sufficient to ensure long-term reliability.
Are these transformers fire-resistant?
Yes, they are designed with excellent flame-retardant and self-extinguishing properties, providing high levels of safety for critical infrastructures like subways and tunnels.
Can they operate at high altitudes?
Standard models are designed for altitudes up to 2500 meters. For applications exceeding this height, specific adjustments or derating may be required.
