Oil-immersed transformer is a new type of high-performance transformer with more reasonable structure and better performance, its three-dimensional rolled iron core due to its three core columns are equilateral triangular three-dimensional arrangement, there is no air gap in the magnetic circuit, the winding is more compact, the length of the three magnetic circuits is the same, and they are all the shortest, and the cross-sectional area of the iron core core columns is more close to the round shape, so the performance is further improved, the loss is lowered, the noise is lowered, and the three balances are made to reduce the third harmonic component, the product is more suitable for the urban and rural areas and the transformation of the power grids of the industrial and mining enterprises, and the product is more suitable for the combined transformers and the transformers used in pre-assembled transformers and preloading transformers for transformer substations.

Types of Oil-immersed Transformers

There are several types of oil-filled transformers. Here are a few of the most common below.

Single-phase transformers use one pair of windings. It’s used in lower-load situations, such as rural areas.
Three-phase transformers are made up of three pairs of windings. The windings typically go around a core sectioned into three parts. Three-phase transformers are used in higher-load areas and can supply three circuits with energy.
Power transformers are designed to handle much higher loads. They can step voltages up or down and transmit a current from one place to another.
Distribution transformers transmit lower voltages from the electrical grid to homes and businesses. They are much smaller than power transformers.
Pole-mounted transformers are connected to an electrical pole.
Pad-mounted transformers are mounted to a concrete pad on the ground.
