Product Description

Product Description

Oil-immersed Transformer

S11-M-30~2500/20-10 fully sealed oil-immersed transformer is suitable for AC 50Hz, rated working voltage 10kV, 20kV and below power system, as petroleum, metallurgy, chemical, textile, light industry and other enterprises and large dust places of the distribution transformer.

Oil-immersed transformer is a type of transformer that uses insulating oil for both cooling and electrical insulation. It is widely used in power transmission and distribution due to its high efficiency, reliability, and ability to handle heavy loads. The transformer oil absorbs the heat generated by the core and windings and dissipates it through natural air or forced cooling systems, ensuring stable operation and extending the transformer's lifespan. Most modern oil-immersed transformers are hermetically sealed, which prevents contamination by moisture and air, enhancing durability. These transformers are commonly used in substations, industrial facilities, power plants, and renewable energy systems like wind and solar farms. They are designed for high voltage and heavy-duty applications, offering superior heat dissipation and overload capacity compared to dry-type transformers.
