There are many differences in the application scenarios of resin dry-type transformers and impregnated dry-type transformers, as detailed below:

Commercial and civil construction fields

• Resin dry-type transformers: Widely used in urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, etc. For example, in large shopping centers, they can be installed in load centers to supply power to lighting, air conditioning, elevators, and other equipment. Their safety, fire resistance, and pollution-free characteristics ensure electrical safety in densely populated areas.
• Impregnated dry-type transformers: Also suitable for high-rise buildings and other locations, but due to relatively poor heat dissipation conditions, their application is relatively limited in some modern large commercial buildings with high spatial layout and heat dissipation requirements. However, they are still used in some older high-rise buildings with extreme fire resistance requirements and ample space.

Industrial field

• Resin dry-type transformers: In factories, mines, metallurgy, chemical industries, etc., they provide stable power supply for various production equipment. For example, in the production workshop of a chemical enterprise, their good moisture-proof and corrosion-resistant properties can adapt to the humid and corrosive gas environment in the workshop.
• Impregnated dry-type transformers: Often used in industrial locations with extremely high fire resistance requirements, such as hydropower stations. Their high insulation and heat resistance levels do not produce large amounts of smoke during high-temperature combustion, which can reduce the hazards during a fire and ensure the safety of equipment and personnel.

Transportation field

• Resin dry-type transformers: In transportation hubs such as airports, subways, and train stations, they can meet the power needs of lighting, ventilation, security checks, etc. Their low noise and significant energy-saving characteristics help reduce noise pollution and operating costs in transportation hubs.
• Impregnated dry-type transformers: In some locations with extremely high fire resistance requirements, such as subway vehicle depots and signal control rooms at train stations, their high fire resistance can ensure the safe operation of equipment and prevent fire from damaging critical equipment like traffic signals.

Energy field

• Resin dry-type transformers: In offshore oil platforms, wind farms, and other locations, their weather resistance and corrosion resistance can adapt to harsh natural environments at sea. For example, in offshore substations for offshore wind power, they can boost the electrical energy output from wind turbines for transmission to the land power grid.
• Impregnated dry-type transformers: Can be applied in substations of land wind farms with high fire resistance requirements, where their high insulation and heat resistance levels can ensure equipment safety during high-load operation.

Special locations

• Resin dry-type transformers: Suitable for laboratories and other places with high environmental requirements and strict fire and explosion prevention requirements. Their stable performance and safety guarantees can ensure the normal operation of testing equipment.
• Impregnated dry-type transformers: In some military facilities and data centers with special fire resistance requirements, their excellent fire resistance can prevent fires from causing devastating damage to important data and equipment.
