Guoanda: The company has successfully developed fixed automatic fire extinguishing systems for converter stations and substations.

On September 27, Guo Anda stated on the interactive platform that the company has successfully developed a fixed automatic fire extinguishing system for converter stations and substations through independent innovation. The "compressed air foam fire extinguishing technology" used has been recognized as a key technology for fire protection in ultra-high voltage converter stations, filling the technological gap in efficient fire extinguishing for ultra-high voltage converters at home and abroad, providing important guarantees for the safe and stable operation of key power transmission and transformation equipment in ultra-high voltage converter stations and large substations. Currently, this product series has been widely used in many major energy projects at home and abroad, including the 1100kV Changji/Guquan converter station, 800kV Yazhong/Butuo/Wuhan converter station, 750kV Wubei/Santanghu/Kashi substation, Minyue Interconnection converter station, and has successfully been applied in the Belt and Road Initiative project, such as the Pakistan Mohra Direct Current Project.
