Recently, ZTT Submarine Cable Co., Ltd. (hereinafter referred to as the “ZTTSC”) successfully completed the factory test and delivery of 500kV AC submarine cable for the second-circuit transmission line project for Zhejiang Zhoushan Networking North Passage. The leaders and experts from Zhejiang Electric Power Co., Ltd. affiliated to State Grid, China Electric Power Research Institute, State Grid Electric Power Research Institute, State Grid Zhejiang Electric Power Research Institute, Construction Branch of Zhejiang Electric Power Co., Ltd. of State Grid (consulting company), Zhejiang Qiming Power Group Co., Ltd. and ZTT Group witnessed the factory test.

In the production process of the second-circuit transmission line project of Zhoushan Networking North Channel in Zhejiang, ZTTSC introduced the performance excellence management standard, practiced the core valueswith “Precision Manufacturing & Practical Innovation” based on the “project manager system” and the implementation of major project with “one-system and three-training”, conducted thoughtful and effective process on the implementation of the project, fully considered the importance and particularity of the project, conducted all-round investigations and technical trainings on all production processes of the project, and implemented the participation of people concerned and emphasis on everyone, guaranteeing safe and stable production of processes, and securing the quality and quantity to achieve continuous production of the second-circuit 500kV submarine cable in 17.4 km, and the product delivery is completed in advance.

Successful delivery of Zhoushan second-circuit 500kV network transmission and transformation project is another milestone in continuous and stable production of large-length & ultra-high voltage submarine cable achieved by ZTTSC, further laying the leader foundation of ZTTSC in the industry, and also marking that ZTT is at international leading level in the field of ultra-high voltage submarine cable.

Xue Jianling, the general manager of ZTTSC, said global submarine cable was booming. ZTT would actively participate in the globalization layout of submarine cable, develop the strategy with “systematic and general contracting developments of submarine cable” under the guidance of Chinese strategy on the acceleration on the construction of the maritime power, and provide all-around supports and services in the fields of AC and DC submarine cable transmission technology, construction of offshore wind power project, system integration service as well as cooperation and development of wind power resource.
