outdoor 3-phase oil transformer is a type of electrical transformer that is designed to be used outside in an open environment. It has three phases, each consisting of a primary and secondary winding, and uses oil as a coolant and insulator.
The oil in the transformer helps to cool the windings and provide insulation between them. The transformer is designed to be weatherproof, so it can withstand exposure to rain, wind, and other outdoor elements.
Outdoor 3-phase oil transformers are commonly used in power distribution systems to step down high-voltage power from the transmission lines to a lower voltage level suitable for use in homes and businesses. They can be found in a range of sizes, from small pole-mounted transformers to large substations.
Regular maintenance and testing of the transformer are crucial to ensure its continued operation and prevent any potential failures that could cause power outages or damage to the transformer.
