Product Description

The insulation of transformers can be divided into internal insulation and external insulation. Internal insulation refers to the insulation of various parts inside the oil tank, while external insulation refers to the insulation between the upper part of the bushing and the ground. Internal insulation can be divided into two parts: main insulation and longitudinal insulation. The main insulation is the insulation between the winding and the grounding part, as well as between the windings. In Oil Immersed Transformers, the main insulation structure is most commonly used with oil-paper barrier insulation.

The Oil Immersed Transformer has the characteristics of good heat dissipation, low loss, large capacity, low price, etc. Its main role in the power grid is the conversion of electric energy, that is, the conversion of voltage level. It is understood that most of the power transformers operating in the power grid are oil-immersed transformers.
