On June 16, the world's highest voltage grade 500kV XLPE insulated submarine cable accessory system supplied by our company for the second transmission line project of Zhoushan 500kV Network North Channel of Zhejiang successfully passed the engineering completion test.

The first and second circuits of the Zhoushan 500 kV network transmission and transformation project in Zhejiang alluse our 500kV submarine cable accessories. The first circuit has been successfully completed in the early stage and put into operation. Our company is the only manufacturer in China with the actual operation performance of 500kV submarine cable accessories. This is a full demonstration of the company's major technology research and development capabilities. This reflectsthe trust and recognition of the State Grid for the company's excellentquality.

The Zhoushan 500 kV project is thelargest and most technically difficult cross-sea network transmission and transformation project in China's electric power construction history. Thisprocess created 14 world records including the construction of the world'stallest transmission tower and the world's first 500 kV cross-linked polyethylene submarine cable.The world record indicates that China's marine transmission technology continues to lead the world, and it also marks the fullaccess and full coverage of the ultra-high voltage power grid in ZhejiangProvince.
