Safe, Efficient and Environmentally Friendly Power Distribution Solution

The SC(B) Series Dry-Type Transformer is a high-performance cast resin transformer designed for reliable power distribution in commercial, industrial, infrastructure, and renewable energy applications. Utilizing advanced vacuum casting technology and high-quality epoxy resin insulation, SC(B) transformers provide excellent fire resistance, moisture resistance, and environmental protection without the need for insulating oil.

Compared with oil-immersed transformers, SC(B) dry-type transformers offer higher safety, lower maintenance requirements, and superior suitability for indoor installations, making them an ideal choice for modern buildings and critical power systems.
