Solar/Wind Transformers

Our Solar Inverter Duty Transformers are engineered to meet the demanding requirements of modern solar PV systems. Acting as the critical link between solar inverters and the grid, these transformers are optimized for energy efficiency, harmonic tolerance, and robust thermal performance.

Key Features

  • High Efficiency & Low Losses : Designed to maximize power transfer while minimizing core and copper/aluminium losses.
  • Thermal Stability : Built to withstand fluctuating load cycles and ambient temperature extremes common in solar applications.
  • Harmonic Tolerance : Withstands voltage distortions and switching transients generated by inverters.
  • Silent & Compact Design : Low noise emission and space-efficient configurations.
  • Custom Engineered : Oil-immersed, with optional OLTC/DETC tap changers and enclosure types.

Aluminium Foil Winding Process

For the low-voltage windings of our Solar Inverter Duty Transformers, we utilize high-conductivity aluminium foil winding technology, offering several performance and reliability benefits. This manufacturing process includes :

  • Continuous Foil Layering : Precision-guided machines layer aluminium foil and insulating paper alternately, ensuring uniform electrical stress distribution and tight coil geometry.
  • High Pressure Bonding : Windings are subjected to controlled pressure to eliminate air gaps, improving mechanical strength and impulse voltage withstand capability.
  • Automated Edge Welding : The aluminium foil edges are TIG welded or cold pressure welded, ensuring robust electrical continuity and long-term durability.
  • Enhanced Short-Circuit Strength : Flat conductor profile increases surface area for better cooling, which is critical in solar inverter operations.
  • Corrosion Resistance : Treated aluminium materials resist oxidation, even in high-humidity or coastal installations.
