Container-type Wind/Solar Power Compact Substation

The container-type compact substation is a dedicated power distribution unit for wind and solar farms. It steps up the low-voltage output from inverters to 40.5 kV for grid connection. Housed in a standard shipping-container enclosure, it offers modular design, small footprint and easy on-site installation — ideal for large-scale renewable energy projects.

  • Large capacity — miniaturized design up to 9 MW (dry-type ≤ 6300 kVA, oil-type ≤ 9000 kVA)
  • High reliability — circular windings, 1.2× overload capacity, zero oil leakage
  • Smart & remote — remote control, real-time monitoring
  • Top-level corrosion resistance — CX-VH class
  • High efficiency — meets Tier 2 international standard (≥ 99.532%)
  • Modular & compact — small footprint, easy install & overhaul
