30kv Oil-Immersed Transformer for Distribution Networks with CE Certification

30kv Oil-Immersed Transformer for Distribution Networks with CE Certification. High Heat Dissipation: Insulating oil provides superior thermal conductivity for rapid heat removal via natural convection or forced circulation. Superior Insulation: Oil breakdown strength of 25-35kV/mm offers reliable high-voltage resistance compared to air media. Low Cost & High Efficiency: Lower material costs and simpler structures ensure high cost-efficiency with 98% efficiency rating. Long Maintenance Cycle: Sealed design resists moisture and dust; maintenance required only every 1-3 years. Strong Overload Capacity: High heat capacity allows bearing loads exceeding rated capacity during short-term peak hours. Comprehensive Certifications: Meets IEC, ANSI, GB standards with CCC, CE, UL, GSA, GOST, and COC certifications. Flexible Customization: Customizable core material, winding material, voltage regulator steps, and insulation class.
