Pressboard Selection for Dry-Type Transformers

Apr 20,2026
Transformer Pressboard is an essential solid insulation material in oil-immersed transformers. Different transformer types vary significantly in voltage level, short-circuit withstand capability, thermal requirements, and mechanical stress. Therefore, the selection of pressboard must be optimized according to the transformer’s structure and operating conditions.
