What are the cooling methods for dry-type transformers?
Discover the 3 main cooling methods for dry-type transformers that ensure optimal performance and longevity. Open Air Natural (AN) cooling relies on natural convection for well-ventilated spaces (ambient ≤40°C). Forced Air (AF) cooling uses temperature-activated fans to boost capacity by 15-25%. Encapsulated resin cast cooling provides IP54 protection with 0.2-0.3 W/m·K thermal conductivity. At LuShan (est. 1975), we engineer all three types with 49 years' expertise, serving industries from renewable energy to medical facilities. Our dry-type transformers feature: IEC 60076-11 compliance, ≤65dB noise levels, and smart temperature monitoring. Learn which cooling solution best fits your application's load requirements and environmental conditions.
