Prefabricated Inverter Substation

10MW Converter & Step-up Cabin

The largest station in the line: 10,000 kVA of conversion and MV step-up in a single 40-foot cabin, with the PCS, oil-immersed transformer, MV switchgear and auxiliaries pre-installed and pre-tested. 1040–1500 V wide-range DC across 4 or 8 branches, 20–35 kV AC output, islanding and black-start with LVRT and HVRT, and four-quadrant active and reactive power control.

  • 10,000 kVA
  • 20–35 kV
  • 1040–1500 V DC
  • IP55
