What are the purposes of transformer winding drying?
Transformer winding drying serves three vital purposes: (1) Boosting electrical insulation strength by removing 6-8% moisture content that causes leakage currents and breakdowns, critical for high-voltage transformers; (2) Stabilizing material dimensions to prevent swelling-induced structural issues in compact transformers; (3) Preventing insulation aging by eliminating moisture-induced chemical reactions that degrade materials. This process reduces downtime by 60% in power systems and extends equipment lifespan by 30%, especially for renewables and industrial applications. Lushan Transformer—with 49 years of manufacturing expertise—explains how proper drying aligns with IEC standards to ensure grid stability and safety.
