Product Description
A three-phase oil-immersed transformer is a type of electrical transformer that utilizes oil as a cooling and insulating medium. It is designed to transform electrical energy between three-phase alternating current (AC) power systems, typically found in industrial and utility applications. These transformers are constructed with multiple windings and a core made of laminated steel to efficiently step up or step down voltage levels while maintaining stable electrical characteristics. The oil within the transformer not only serves to cool the unit but also provides insulation between windings and the transformer's core, ensuring safe and reliable operation.
High efficiency and economy: Oil immersed transformers usually have high efficiency and can effectively reduce energy losses, thereby saving energy costs in long-term operation.
