Product Advantage

1. No oil, no pollution, flame retardant, self-extinguishing and fire prevention.

2. Low loss, high efficiency and low noise. It can run long time under 125% rated load under the forced air-cooling condition and is equipped with intelligent temperature controller. The functions of fault alarm, over temperature  alarm, over temperature trip and black gate. It is connected with computer through RS485 serial interface and achieves centralized monitoring and control.

3. Small local discharge (under 30 PC) and high reliability, can ensure long-term safe operation, life up to 30 years.

4. Resistance to crack and temperature change, high mechanical strength, strong ability to resist sudden short-circuit.

5. Good moisture-proof property, it can run normally under 100% humidity and can be put into operation without drying treatment after shutdown.

6. There is no need for a separate transformer room, core maintenance or load-bearing beam  saving civil land and occupation No oil, so it will not produce toxic gas to pollute the environment.  No need of oil collecting pits or other ancillary buildings which reduces the cost of construction Easy installation, no debugging, almost no maintenance; No need to replace or check the oil, low operation and maintenance cost.

Working Environment

Dry-type transformers thrive in indoor, moderate-climate, fire-sensitive, and low-contamination environments, prioritizing safety, space efficiency, and compliance with strict regulatory standards. Their air-cooled design and non-flammable materials make them the preferred choice for urban, commercial, and sensitive applications, while technical adaptations (IP ratings, insulation classes) extend their usability across diverse but non-extreme operational conditions.

Working Environments for Dry-Type Transformers
Dry-type transformers, distinguished by their air-cooled, oil-free design, are engineered for versatility in diverse operational settings where safety, space efficiency, and environmental compatibility are critical. Their typical working environments include:
1. Indoor & Enclosed Spaces
Dry-type transformers excel in indoor applications due to their non-flammable nature (no insulating oil), making them ideal for:

Commercial/Residential Buildings: Installed in basements, utility rooms, or rooftop enclosures of offices, apartments, and shopping centers, where fire safety codes restrict oil-filled equipment.
Data Centers & Server Rooms: Requiring clean, low-risk power solutions, these transformers operate in controlled environments with strict temperature (20–25°C) and humidity (40–60%) controls to prevent dust and moisture-related failures.
Industrial Control Rooms: Integrated into motor control centers or automation systems, where proximity to sensitive electronics demands non-conductive, low-maintenance power conversion.
2. Moderate Climate & Low-Moisture Zones
They thrive in ambient temperatures ranging from -25°C to +40°C with relative humidity ≤95% (non-condensing), suitable for:

Mild Outdoor Environments (with IP-rated enclosures, e.g., IP20–IP54): Deployed in outdoor substations of urban areas, campuses, or light-industrial zones, protecting against dust, water splashes, and minor physical impacts.
Temperate Regions: Avoiding extreme heat/cold or high humidity, where their air-cooled design (natural or forced ventilation) efficiently dissipates heat without liquid coolant.

Product productive process

In addition to providing convenience for People's Daily electricity needs in the city, substations are also widely used in wind farms, photovoltaic power stations, hydropower stations, nuclear power plants, hub substations, important converter stations, backbone power grids, important transmission channels and other energy infrastructure scenarios.
