A dry-type high voltage transformer is an electrical device used to step up or step down voltage in high voltage applications. It is designed without liquid or oil insulation, making it suitable for indoor installations where flammability or environmental concerns exist.
Transmitting electrical energy between different voltage levels in a high voltage system. It steps up or down the voltage level according to the turns ratio of the transformer, enabling efficient power transmission and distribution.
Dry-type high voltage transformers are commonly used in a variety of applications including power distribution systems, industrial facilities, renewable energy installations and commercial buildings. They are suitable for indoor installations where the presence of flammable liquids or environmental concerns limit the use of oil filled transformers.
Dry-type high-voltage transformers have several advantages over oil-immersed transformers. They are self-cooling or air-cooled and require no cooling oil or external cooling systems. They are also more resistant to fire and require less maintenance. In addition, dry-type transformers have a longer service life and can operate in a wider range of ambient temperatures.
