HJATIS HJ-CSS-R 40.5kV 6300kVA renewable energy step-up substation, featuring heavy-duty cooling and wide voltage tolerance for direct solar and wind power grid connection
HJ-CSS-R Series Renewable Energy Step-Up Substation

Up to 40.5kV / 6300kVA / Solar & Wind Ready / Plug & Play

The HJ-CSS-R Series Renewable Energy Step-Up Substation is a heavy-duty, highly integrated turnkey solution engineered specifically for utility-scale photovoltaic (PV) and wind power generation. It seamlessly aggregates low-voltage AC power from solar inverters or wind turbines (up to 1.14kV) and steps it up directly to medium-voltage transmission grids (up to 40.5kV). Housed in an extreme-weather enclosure, it guarantees maximum energy yield and grid compliance with minimal on-site civil works.

 

Ideal for Utility-Scale Renewable Projects:

  • ✓ Large-Scale Ground-Mounted Solar Farms
  • ✓ Onshore Wind Power Generation Plants
  • ✓ Floating Solar PV Installations
  • ✓ Hybrid Renewable Microgrids & Energy Storage (BESS)
