Product Overview

Our oil-immersed distribution transformers range from 30kVA to 2500kVA, with voltage levels up to 35kV. They are widely used in power utilities, renewable energy, industrial facilities, railway systems, and urban infrastructure. Designed to IEC and ANSI standards, our transformers offer high efficiency, low losses, and long service life, suitable for both indoor and outdoor environments.

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.
