What Are the Similarities and Differences Between Epoxy Resin Cast Dry-Type Transformers and Impregnated Dry-Type Transformers?
This technical comparison examines epoxy resin cast and vacuum pressure impregnated (VPI) dry-type transformers - the two dominant types in global power systems. Key differences include: Short-Circuit Performance: Epoxy cast units offer superior mechanical strength (withstand 25-30× rated current) due to monolithic cylindrical winding structures Thermal Management: Epoxy designs feature optimized cooling ducts (ΔT 10-15°C lower than VPI) through axial airflow channels Environmental Resistance: Epoxy encapsulation provides IP54-rated protection with
