Description

A distribution transformer is a transformer that provides a final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer
hermetically sealed oil transformer is a type of electrical transformer that uses a liquid, such as oil, as a cooling and insulating medium. So, it is also called a liquid transformer.
Oil provides good dielectric insulation and helps to prevent the corrosion of internal components.
Important, oil-filled transformers require regular maintenance and may pose an environmental hazard in the case of oil leaks or spills.
