Brief instruction：

220kV three-phase oil immersed on-load voltage regulating transformer brings about a series of

 major transformations in terms of material, technique, and construction.

It is characteristic of compact construction, low weight, high efficiency, low loss, low noise, and reliability of performance. 

The product can reduce considerable losses on grid and operational costs and extend distinct economic efficacy.    

What is an Oil Immersed Transformer?

 An oil-immersed transformer, also called Oil filled transformer,

 is a kind of voltage transformation device utilizing the oil cooling method to reduce the transformer temperature.

How does an oil immersed transformer work?

An Oil Immersed Transformer involves the oil cooling method to reduce its temperature. 

Its body is connected to the welded steel oil tank, which is full of insulation oil. 

These transformers work because the heat of the coil and iron core is transferred into the insulation oil.

What are the advantages of oil immersed transformer?

Oil-immersed electric transformers are the most commonly used equipment mainly 

because of their simple structure and reliable operation. 

It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.
