The three-phase dry-type transformer is an energy-saving transformer product that meets the latest national secondary energy efficiency standards. Based on the SCB13 model, this dry transformer has significantly improved energy efficiency and effectively reduced operating noise through the optimization of core structure, coil design, and production process. With its outstanding energy conservation and environmental protection performance, this series of 3 phase dry type transformer will become one of the key dry-type transformer models promoted by the state in the next few years.
The three-phase dry-type transformer is a new model of power transformer in 2021. The SCB14-1250KVA transformer meets the requirements of a second-level energy efficiency dry-type transformer and is a new type of energy-saving dry-type transformer that the State Grid is vigorously promoting.
The three-phase dry-type transformer achieves the goals of reducing no-load, load losses, and noise by combining new materials, new processes, independent research and development with technology introduction, and optimizing and innovating the coil structure and core design.
