Product Overview
Wind and solar power substations are dedicated step up and grid connection equipment for photovoltaic power plants and wind farms. Customized to meet the characteristics of new energy power generation, they adopt an integrated prefabricated cabin structure, integrating a step up transformer, high voltage switch, low voltage collector, lightning protection, and intelligent monitoring into one unit. This allows the low voltage power output from inverters or wind turbines to be stepped up to 10kV/35kV and connected to the grid. The products feature harmonic resistance, fluctuation tolerance, strong overload protection, high protection, and intelligent operation and maintenance. They are widely used in centralized photovoltaic, onshore wind power, offshore wind power, and integrated wind solar storage projects, adapting to harsh environments such as outdoors, deserts, plateaus, and coastal areas, and meeting the requirements for unattended, long term stable operation.
