What Is an Oil Immersed Transformer and What Is Its Function?

An Oil Immersed Transformer is a type of power transformer that uses insulating oil for both cooling and insulation. It is widely used in power systems to step up or step down voltage. The windings and core of the transformer are fully submerged in special transformer oil, which ensures safety and stability during long-term operation thanks to its excellent insulating and heat dissipation properties. Oil immersed transformers are commonly applied in power transmission projects, industrial and mining enterprises, commercial buildings, and rural power grid upgrades. They are indispensable core equipment in power transmission.

How Does an Oil Immersed Transformer Work?

The operating principle of an oil immersed transformer is based on electromagnetic induction. When current flows through the primary winding, it generates magnetic flux in the core, which induces voltage in the secondary winding, thus achieving voltage transformation. The core components of the transformer are the iron core and windings, while the exterior includes the oil tank, radiator, and protection devices. During operation, the windings generate heat, which is transferred to the oil and then dissipated through the tank and cooling system, helping to maintain a stable internal temperature and extend the transformer's service life.

What Are the Advantages of Using an Oil Immersed Transformer?

First, oil immersed transformers offer excellent heat dissipation and insulation performance, allowing them to operate reliably even under overload conditions. Compared to dry-type transformers, they have a more compact structure and lower manufacturing costs at the same capacity, making them suitable for outdoor or harsh environments. Additionally, they have long maintenance cycles and service lives, which is why they are currently the most common and widely used type of transformer.

What Should Be Considered When Choosing an Oil Immersed Transformer?

When selecting an oil immersed transformer, you should determine the required capacity, voltage level, and cooling method based on the application scenario. Other important considerations include manufacturing quality, material standards, energy efficiency, and whether the product includes comprehensive protection systems. Choosing a supplier with reliable after-sales service and technical support is also key to ensuring long-term stable operation. A high-quality oil immersed transformer provides solid support for the safe operation of any power system.
