APPLICATION SCENARIO
-
Onshore Wind Farms
The prefabricated step-up cabin is ideal for onshore wind power plants, where each group of wind turbines requires a compact and reliable solution to boost voltage from 0.4kV to MV/HV levels (11kV/33kV/66kV) before transmitting power to the main collection system.
-
Offshore Wind Power Platforms
Due to its fully enclosed, anti-corrosion, and modular design, the cabin is suitable for offshore environments with high humidity, high salinity, and strong winds. It provides stable operation and easy maintenance for offshore wind projects.
-
Distributed Wind Energy Systems
For distributed small-to-medium wind turbine clusters, the cabin offers a plug-and-play substation solution with minimized civil work, rapid installation, and a reduced project timeline.
-
Wind Turbine Hybrid Projects (Wind + Solar)
In hybrid renewable power stations that combine wind and solar generation, the cabin serves as a centralized step-up unit connecting multi-energy outputs into the MV/HV grid.
-
Remote & Harsh Environment Power Stations
The robust structure allows deployment in deserts, coastal areas, mountains, and cold regions, ensuring safe grid connection under extreme temperatures, sand, dust, moisture, and vibration conditions.
-
Temporary or Mobile Wind Power Demonstration Sites
The modular and transportable design makes it suitable for temporary installations, pilot projects, research sites, or rapid deployment in newly developed wind energy zones.
