Faqs:
  • What efficiency level does this transformer achieve and how is it accomplished?
    This transformer achieves Energy Efficiency Level 1 through optimized iron core processing using laser-cut silicon steel sheets, which reduces no-load loss by 15%-18% and magnetic resistance by 18%-22% compared to conventional cores.
  • How does the winding design contribute to performance and longevity?
    The winding uses transposed conductors that evenly distribute current across the conductor cross-section, reducing skin effect loss by 25%-30% and preventing local overheating. Combined with 155-class temperature-resistant insulation, this extends service life to over 25 years.
  • What safety features are included in the oil tank system?
    The intelligent oil tank system provides real-time oil level monitoring with audible and visual alarms for abnormalities. When oil temperature exceeds 65°C, automatic cooling fans activate, increasing heat dissipation efficiency by 40% to prevent overheating and ensure stable operation.
