Epoxy resin with fiberglass has features with flame retardant and easy to extinguish.
It could be installed near by the load center to reduce cost and circuit energy consumption.
Non pollution. There is no oil in the transformer, no need to maintain. It could save a lot of maintenance time and cost.
It could work in the 100% humidity environment. There is no need to dry it in advance when it resumes operations.
Low loss, low noise and effective heat dissipation.
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.
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.
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.
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.
Dry-type transformers are highly fire-resistant, environmentally friendly due to the absence of toxic oils, require virtually no maintenance, and can be installed close to load centers to reduce energy loss.
Yes. Designed with high-quality epoxy resin and moisture-proof insulation, they can reliably operate in environments with up to 100% humidity without requiring pre-drying before resumption of service.
These transformers utilize Class H insulation, which withstands operating temperatures up to 180°C, providing exceptional thermal durability and safety limits under heavy load conditions.
Standard models use Air Natural (AN) cooling. However, for higher capacities (typically 1000kVA and above) or temporary overload requirements, Air Forced (AF) cooling systems can be configured.
The standard protection level is IP20. However, enclosures can be fully customized to IP21, IP30, or other ratings to meet specific indoor dust-proof or outdoor environments.
