Description

Liquid filled transformers, also known as oil immersed transformer, are electrical transformers that use a liquid as a coolant and insulating medium. The transformer is immersed in a tank filled with oil, which helps to dissipate the heat generated during operation and provides insulation between the high-voltage and low-voltage windings.

Oil immersed transformers are available in various sizes and voltage ratings, from small distribution transformers to large power transformers used in electrical power grids. They are commonly used in a range of applications, such as in power generation plants, substations, and industrial facilities.
