Advantages
1. Fireproof: epoxy resin with fiberglass has features with flame retardant and easy to extinguish.
2. Economical: it could be installed near by the load center to reduce cost and circuit energy consumption.
3. Maintenance-free,non pollution. There is no oil in the transformer, no need to maintain. It could save a lot of maintenance tine and cost.
4. Moisture-proof. It could work in the 100% humidity environment. There is no need to dry it in advance when it when it resumes operations.
5. Low loss, low noise and effective heat dissipation.

Applications of Dry-type Transformer
1. Indoor Commercial Spaces
Ideal for shopping malls, office towers, and hotels—its oil-free, flame-retardant design eliminates fire/leak risks in enclosed areas, powering HVAC systems, elevators, lighting, and commercial appliances while operating quietly to avoid disrupting public environments.
2. Data Centers & Telecom Facilities
Critical for powering servers and network equipment, as its stable voltage output prevents data loss from fluctuations. Its dust-proof and high-temperature-resistant features suit the controlled, high-density electrical environments of data hubs.
3. Industrial Workshops
Used in electronics, machinery, and food processing plants—where oil-based transformers pose contamination risks. It withstands industrial dust and moderate heat, supporting continuous operation of production lines with low maintenance needs.
4. Renewable Energy & Urban Grids
Integrated with solar/wind energy storage systems to convert and distribute clean power. Also deployed in residential neighborhoods and urban medium-low voltage grids, ensuring safe, efficient electricity supply for households without environmental hazards.
