Product details

Built for new-energy power collection, this custom outdoor European box substation accepts either 35 kV or 10 kV input and steps it down to 440 V output. An oil-immersed booster transformer and its switchgear share a single IP54 enclosure, making the unit purpose-fit for step-up duty on solar, wind, and energy-storage sites.

Design & Construction

  • Layout pairs a distribution room with an externally mounted oil-immersed booster transformer
  • Oil conservator plus perforated panelling keeps heat dissipation effective
  • Blue-roofed steel enclosure with hinged access doors sits on a solid base frame
  • IP54-rated and configurable for photovoltaic, wind, and energy-storage installations

Applications

Suited to photovoltaic plants, wind farms, and battery energy-storage systems that need new-energy step-up and grid interconnection.
