Dry-type transformers are valued for their safety, compact size, and suitability for indoor environments (due to no flammable cooling oil). Their typical applications span various industries and settings where fire safety, low maintenance, and adaptability to enclosed spaces are prioritized. Here are their key use cases:

1. Commercial and Public Buildings

Office Complexes & Malls: These spaces require reliable power distribution within limited indoor areas. Dry-type transformers, often installed in basements or utility rooms, step down high-voltage grid power to low-voltage (e.g., 400V) for lighting, HVAC, and electrical equipment.

Hospitals & Healthcare Facilities: Critical environments where fire risk must be minimized. Dry-type transformers ensure uninterrupted power for life-support systems, medical devices, and emergency lighting without the hazard of oil leaks.

Schools & Universities: Safe power distribution for classrooms, labs, and dormitories, where proximity to students and staff demands low fire risk.

2. Industrial Settings  

Factories & Manufacturing Plants: Used in indoor production areas with machinery, conveyor systems, and control panels. They step down voltage for motors, robotics, and assembly lines, especially in industries like automotive, electronics, and food processing (where cleanliness and safety are key).

Data Centers & Server Rooms: High-density power 需求 (for servers, cooling systems) requires transformers that operate efficiently in enclosed spaces. Dry-type models with forced air cooling (AF) handle high loads without fire risks, ensuring uninterrupted data operations.

3. Infrastructure and Utilities

 Railway Stations & Metro Systems: Installed in control rooms, ticketing areas, and platform lighting systems. Their compact design fits into limited spaces, and flame-retardant variants (e.g., epoxy-cast) meet strict safety standards for public transit.

 Airports: Power distribution for terminals, baggage handling systems, and runway lighting. Dry-type transformers are preferred for indoor utility rooms near passenger areas.

4. Renewable Energy Systems

 Solar Power Installations: Used in solar inverters to convert DC power from panels to AC, then step up/down voltages for distribution. Their durability in indoor inverter rooms (or weatherproof enclosures for outdoor use) makes them ideal for solar farms.

 Wind Farms: Smaller dry-type transformers may be used in control systems or to step down voltage from turbines to local grids, especially in onshore facilities with indoor equipment rooms.

5. Residential Complexes  

High-Rise Apartments: Centralized power distribution in basement utility rooms, stepping down grid voltage to 230V for household use. Their low noise and fire safety reduce risks in densely populated buildings.

 Key Reasons for These Applications

1. Fire Safety: No flammable oil eliminates fire/explosion risks, critical in occupied or enclosed spaces.

2) Compact Design: Fits in tight indoor areas (e.g., utility closets, basements) where oil-immersed transformers (bulky and requiring oil containment) are impractical.

3) Low Maintenance: Minimal upkeep (e.g., dust cleaning) compared to oil-immersed models, reducing downtime in critical operations.

4) Environmental Compatibility: No risk of oil spills, making them suitable for eco-sensitive areas (e.g., hospitals, schools, near water sources).

In summary, dry-type transformers are the go-to choice for indoor, safety-critical, and space-constrained applications across commercial, industrial, and infrastructure sectors
