Product Description
The SC(B) Dry Type Transformer is a high-performance power transformer specifically designed for modern power distribution systems. With the official implementation of China's new energy efficiency standard, GB20052-2020, on June 1, 2021, the permissible loss limits were reduced by 10% to 45% compared to the previous version-surpassing even comparable standards in the EU and the US. The SC(B) Dry Type Transformer is designed in strict compliance with this new standard; specifically, the SCB13 model features an optimized design that delivers comprehensive upgrades in both energy efficiency and reliability.
