As a critical piece of equipment for offshore wind power, GIS plays a very important role in ensuring the reliability, stability, and safety of the entire wind farm operation. Currently, the voltage level of the collector system for large-capacity offshore wind turbines in China has been upgraded from 35kV to 66kV, which requires GIS equipment with larger capacity and greater stability. Based on the current situation, Pinggao Group is committed to technological innovation in the energy sector, focusing on customer development needs, and has developed a compact, reliable, and economical 72.5kV GIS product for offshore wind turbines.
