Dry-type transformer
A dry-type transformer is a voltage conversion device utilizing air or solid insulation instead of liquid coolants, featuring epoxy resin-encapsulated or non-encapsulated windings for enhanced fire safety in confined spaces. Dominating applications in hospitals, metro systems, and data centers (2025 EU Directive mandates IP54-rated units for smart buildings), its forced-air cooling systems achieve 98.5% efficiency under IEC 60076-11 standards. Modern variants integrate IoT-enabled thermal sensors and comply with 2027-required RoHS-III non-halogenated materials, making them indispensable for offshore wind farms and AI server farms requiring explosion-proof designs. NEMA TP-1 certified models now dominate 68% of North American industrial upgrades due to reduced carbon footprint (-40% vs oil-immersed counterparts).
