Recently, the world's first long-term exchange of 500KV XLPE insulated submarine cables came out in a smart workshop of Jiangsu Hengtong High-voltage Submarine Cable Co., Ltd., a subsidiary of Hengtong Power Industry Group, after the technology of '500kV cross-linked polyethylene insulated fiber optic composite submarine cable It is learned that this 500KV submarine cable will be applied to the 500KV mainland network project from Ningbo, Zhejiang Province to Zhoushan, through the identification and appraisal of provincial-level new products and new technologies organized by Jiangsu Economic and Information Commission.
Identification will be on-site
Zhejiang Zhoushan 500kV network project is the world's highest voltage level, the longest cross-linked polyethylene insulated AC submarine project.This project will build two 380 meters high in the world's first power transmission tower, using the world's first domestic 500kV cross-linked polyethylene submarine cable, in Ningbo and Zhoushan set up two cross-regional cross-sea channel for the construction of Zhoushan Islands New Area to provide a strong power security. Relying on the construction of this project will speed up China's submarine cable and ultra-high Cross-tower technology to solve a series of construction, installation and other problems, to promote the development of marine transmission technology, build energy Internet is of great significance.
Zhejiang Zhoushan Islands submarine cable project
Before the production, Hengtong carried out a number of technological innovations on equipment, technological innovation and optimization, and check and check 348 process control points to achieve real-time protection of the entire production process, and finally, after 23 days and nights of struggle, to achieve a continuous extrusion Production 18.15km, is the world's single root without the longest 500kV XLPE fiber composite submarine cable.
