  • Detail

The world's first 500 kV submarine cable has passed the semi-finished product voltage withstand test recently, the world's first 500 kV AC polyethylene submarine cable independently developed by China has passed the voltage withstand test in Jiangsu Hengtong high voltage submarine cable Co., Ltd. and can also purchase multiple sets of equipment at the same time. It is expected to complete production according to the project schedule and will be transported to the Zhoushan project site in late April for laying. Ningbo bridging degree has a linear relationship with colloid melt viscosity. Zhenhai Dapeng Island submarine cable laying project is the first AC 500kV polyethylene insulated submarine cable project in the world. In order to overcome the difficulty of the sound asymmetry project, Zhejiang electric power company and Jiangsu Hengtong high voltage submarine cable Co., Ltd. joined hands, through unremitting efforts, and finally successfully developed a small particle size and organized production. The successful completion of the test marks that China's offshore power transmission technology has reached a new level
