According to different project requirements, Juhonkia can provide transformer solutions for indoor installation, outdoor installation, power distribution rooms, substations, factories, wind power projects, solar power projects, urban grid systems, and industrial power networks.

As a power transformer supplier, Juhonkia focuses on stable operation, high efficiency, low loss, reliable insulation, strong overload performance, and long service life. Customers can choose dry type transformers, oil immersed transformers, distribution transformers, or high voltage power transformers according to voltage level, capacity, cooling method, installation environment, and project standards.

Dry Type Transformer vs Oil Immersed Transformer

Choosing between a dry type transformer and an oil immersed transformer depends on installation environment, safety requirements, capacity, maintenance strategy, and project budget.

Dry type transformers use air or resin insulation systems and are often preferred for indoor installations where fire safety, environmental protection, and low maintenance are important. They are commonly used in commercial buildings, hospitals, data centers, metro systems, factories, and other indoor power distribution rooms.

Oil immersed transformers use insulating oil as both cooling and insulation medium. They are suitable for outdoor installations, higher capacity applications, utility grids, substations, renewable energy projects, and industrial power distribution systems. Oil-immersed transformers usually provide strong heat dissipation and stable operation under demanding load conditions. Competitor educational content also commonly uses this comparison to help buyers select the right transformer type.
