Key Advantages
  • Higher Energy Efficiency - Lower no-load loss (20-30% reduction compared to S11 models) and improved winding structure reduce resistance and load losses.
  • Improved Temperature Rise Performance - Enhanced oil circulation and cooling systems maintain stable operation under load, extending insulation life.
  • Reduced Noise Levels - High-permeability silicon steel and precision manufacturing lower magnetostriction for quieter operation.
  • Robust Mechanical Design - Optimized winding structure and clamping improve short-circuit resistance and reduce vibration.
  • Longer Service Life - Superior materials and structural improvements enable 20-30 years of service under proper conditions.
