500 KVA Dry Type Transformers Core

Yongxing Transformer utilizes high-quality transformer cores crafted from Cold Rolled Grain Oriented (CRGO) steel, ensuring superior performance and longevity. These silicon steel sheets undergo a meticulous manufacturing process, where automated machines cut them to precise dimensions, minimizing air gaps and optimizing excitation current. This careful design significantly lowers noise levels, contributing to the overall efficiency of the transformer.
