Three-phase 50Hz Dyn11 insulated resin cast dry-type power transformer is a power transformer that uses resin insulation material and dry insulation, with high efficiency and safety performance. Compared with traditional oil-immersed transformers, it does not contain oil, which can effectively avoid safety problems such as oil leakage, and has a longer service life
Features of dry-type power transformers
High safety performance: It does not contain oil, avoiding safety problems such as oil leakage.
High efficiency: Compared with oil-immersed transformers, three-phase resin-insulated dry-type power transformers have higher efficiency.
Long life: It is not affected by oil leakage and has a longer service life.
Easy maintenance: Since it does not contain oil, there is no need for oil maintenance and replacement.
Small footprint: Compared with oil-immersed transformers, three-phase resin-insulated dry-type power transformers have a smaller footprint

Application scenarios of dry-type transformers
Three-phase 50Hz Dyn11 insulated resin cast dry-type power transformers are suitable for important or special environments such as high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, and ships. It has the advantages of high mechanical strength, good heat dissipation performance, strong overload capacity, small partial discharge, low loss, low noise, maintenance-free, easy installation, good moisture-proof performance, etc. It can replace the oil-immersed transformer and be directly installed in the load center. It can operate at 120% rated load under forced air cooling conditions and can be put into operation without pre-drying after shutdown.
