Yesterday, at the Jintang Island site of the 500 kV Zhoushan Continental Network Project, three workers completed the spraying of the new graphene heavy-duty anticorrosive coating for the 1064th steel pipe tower on the ground. So far, the new graphene heavy-duty anticorrosive coating, jointly developed by the State Grid Ningbo Power Supply Company and the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, has completed the spraying work on the world's highest transmission tower. These steel pipe towers will be hoisted into the air one after another, and the world's highest transmission tower will be completed in October this year at 380 meters.
The Zhoushan 500kV grid-connected power transmission and transformation project started construction on December 28, 2016. It includes a 500kv Zhenhai-Zhoushan submarine cable and overhead line mixed channel (two channels) and Chunxiao-Zhoushan line booster (one channel). section.
It is understood that the transmission speed of coastal transmission towers is 3-5 times faster than that of inland areas. For this reason, as early as 2016, the State Grid Ningbo Power Supply Company and the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences jointly established a "power grid new material application joint experiment And successfully developed a new graphene heavy-duty anticorrosive coating. The coating can extend the protection life of the transmission tower in the marine atmosphere area and industrial area, and has the characteristics of heat resistance and chemical stability, good thin coating adhesion, anti-icing, and strong salt spray resistance.
