1000kVA Oil lmmersed Transformer

For industrial and commercial applications demanding robust and reliable power distribution, the 1000kVA oil-immersed transformer stands as a cornerstone technology. Engineered for efficiency and durability, this transformer is designed to handle significant electrical loads with consistent performance. Our High frequency Oil Immersed Transformer variant offers enhanced performance for specialized applications requiring superior magnetic properties. The classic three phase 1000kVA Transformer configuration provides the balanced power delivery essential for large-scale operations, from manufacturing plants to data centers. For scenarios combining both high-frequency operation and three-phase architecture, our High frequency three phase Transformer solutions deliver optimized performance, ensuring stable voltage transformation under demanding electrical conditions.


The <产品名字> represents a pinnacle of electrical engineering, integrating advanced materials and design principles to ensure long-term operational stability. Its core is constructed from high-grade, grain-oriented silicon steel laminations, meticulously stacked to minimize core losses (no-load losses) and reduce audible noise. The windings, made from electrolytic grade copper or aluminum, are carefully insulated and configured to handle the rated current efficiently, keeping load losses to a minimum. The entire active part is submerged in a high-quality insulating mineral oil, which serves the dual purpose of providing superior electrical insulation and dissipating the heat generated during operation. This oil is contained within a robust, welded steel tank, often equipped with radiators or cooling fins to enhance the natural oil circulation and heat dissipation process. Key protective features typically include a conservator tank with a silica gel breather to prevent moisture ingress, a Buchholz relay for gas and oil flow fault detection, and pressure relief devices for safety. Designed and tested in accordance with international standards such as IEC and IEEE, this transformer is built for a service life spanning decades with minimal maintenance.
