Understanding IEC 60726 for Dry-Type Power Transformers Dry-type power transformers are critical components in modern electrical distribution networks. Unlike liquid-immersed transformers, they use air or gas as an insulating and cooling medium. This design makes them highly suitable for indoor installations, high-rise buildings, and environmentally sensitive areas where fire hazards must be minimized.
Dry-type transformers rely on air or solid gas insulation. The standards define strict limits for temperature rise based on the insulation material used: 130°C Class F: 155°C
The standard was structured to provide a comprehensive set of technical specifications. The European harmonized version, , offers a clear overview of its contents. The standard was divided into sections covering:
