Power Distribution Transformer Capacity Class

Power distribution transformers are usually divided into two types: oil-immersed transformers and dry-type transformers. Their representatives are S11-M transformers and SCB10 transformers. Since oil-immersed transformers use oil as the insulating medium, the capacity is often larger, and the dry-type transformers are often larger. The capacity specification of the type transformer is easy to be smaller.
