Energy saving Oil Immersed Transformer

For industrial and utility-scale power distribution, selecting the right transformer is critical for operational efficiency and long-term cost savings. Our energy-saving oil immersed transformer is engineered to meet these demanding requirements. Designed as a robust Substation Power Transformer, it provides reliable voltage transformation for primary power distribution networks. This unit is a premier example of a modern Medium Voltage Transformer, expertly constructed to handle typical distribution voltages with superior efficiency. Using advanced core and winding technology, it stands out as a true Energy saving Transformer, significantly reducing no-load and load losses compared to conventional designs. As a high-performance Medium Voltage Oil Immersed Transformer, it utilizes high-grade insulating oil for effective cooling and dielectric strength, ensuring stability and longevity in continuous operation.

The "Energy saving Oil Immersed Transformer" achieves its exceptional performance through meticulous design and high-quality materials. The core is manufactured from high-permeability, cold-rolled, grain-oriented silicon steel. This material, along with our stepped core design and advanced lamination techniques, minimizes core losses and reduces exciting current. The windings are made from oxygen-free copper conductors, chosen for their excellent conductivity and mechanical strength. The insulating oil is a high-performance, inhibited mineral oil that provides superior heat dissipation and maintains its dielectric properties over a wide temperature range. A welded steel tank with reinforced panels ensures structural integrity, while external cooling radiators or fans (depending on the rating) effectively manage heat. Key protection and monitoring features include a Buchholz relay for gas detection, a pressure relief device, a silica gel breather to control moisture, and provisions for oil temperature and winding temperature indicators. These components work in unison to deliver a transformer that is not only energy-efficient but also exceptionally reliable and safe for critical power infrastructure.
