Types of Oil-Immersed Transfomer
Key Features of Oil-Immersed Transfomer
Scientific structural
Based on a traditional structural design and mature manufacturing technology, power transformers have undergone numerous improvements and offer the following advantages:
The spiral winding with longitudinal air ducts provides enhanced internal heat dissipation performance.
Improved effective support at the coil end face increases the transformer’s ability to withstand short-circuit currents.
A new lifting structure and body positioning system have been adopted, ensuring greater reliability during long-distance transportation and operation.
The implementation of a unique and reliable structural design contributes to more stable product performance.
High-quality silicon steel sheets with superior magnetic properties are used in the core, resulting in improved energy efficiency, reduced noise levels, and an overall higher technical standard.
The transformer windings employ a cast structure, while the internal air channels utilize a prismatic configuration. This design expands the heat dissipation space, accelerates air circulation, prevents and delays insulation degradation and moisture absorption, thereby enhancing operational reliability and enabling maintenance-free normal operation.
High-Quality Material
All raw materials used in power transformers undergo rigorous inspection, and all material suppliers are strictly evaluated in accordance with the ISO 9000 international quality management standard.
Oxygen-free copper wire with lower resistivity is selected. After a series of advanced surface treatments, the wire surface becomes smoother and free of burrs or sharp edges, thereby reducing transformer load losses and enhancing electrical performance reliability.
With the improvement of performance levels, silicon steel sheets with lower unit losses are employed, resulting in reduced no-load losses of the transformer.
High-quality laminated wood insulation components are selected, which remain crack-free and stable even under the mechanical stress of short-circuit currents.
The use of premium insulation materials ensures superior insulation performance, enhanced product quality and reliability, and improved operational stability of the transformer.
High-performance rubber sealing materials are selected to provide effective resistance against aging.
Equipment Durability
All components of the power transformer are certified products that comply with the inspection and testing requirements set by relevant national regulatory bodies. These components are designed to operate without causing adverse effects and are environmentally safe. The service life of the equipment can reach up to 40 years, during which no replacement of components or vulnerable parts is required. As a result, the transformer is highly durable and requires minimal maintenance throughout its operational lifespan.

What Is the Difference Between a Power Transformer and a Distribution Transformer?
A power transformer, also known as a main transformer, is primarily used to transfer electrical energy generated by power plants or substations through voltage conversion to the power grid or end users. It serves as core equipment for transmission and transformation in the power system. Power transformers are mainly applied in power lines at voltage levels of 35 kV and above, particularly in critical load centers. They play essential roles in voltage transformation, power transmission, grid stability, and power supply reliability.
In contrast, the primary function of a distribution transformer is to change AC voltage based on the principle of electromagnetic induction. It is widely used in power transmission and distribution systems, as well as in industrial, municipal, transportation, port, commercial CBD, agricultural, and other sectors. Distribution transformers perform multiple functions, including voltage transformation, current transformation, impedance matching, isolation protection, power distribution, and supplying power to equipment.
In summary, power transformers are typically used in transmission lines, while distribution transformers are generally applied at the load end.
