[China Instrument Network Instrument R&D] The poor electricity environment of the island has always plagued the production and life of local residents. As the power capacity continues to increase, there are obstacles to the power transmission. Residents living in the island are often subject to power cuts, even so far. Still in the power state of diesel power generation plus candles. On December 17th, the two transmission technologies of the Zhongtian Technology Cable Co., Ltd. jointly organized by the China Electric Power Enterprise Federation and the Jiangsu Provincial Economic and Information Technology Commission have solved this problem.
Picture from network The two new technologies approved by Zhongtian Technology Cable Co., Ltd. are the world’s first “AC 500kV cross-linked polyethylene insulated optical fiber composite cable (including soft joints)†and China’s first “three-core 220kV submarine optical fiber composite Submarine cable (with soft joints)".
China has a vast sea area, with 3 million square kilometers of sea and 18,000 kilometers of coastline, and more than 6,000 islands along the coast. Experts pointed out that the world's Shanghai cable has been used for over 100 years. The technology mainly focuses on oil-filled insulated cables, oil-impregnated paper insulated cables, and cross-linked polyethylene insulated cables. The 500 kV and above EHV submarine cables are still in blank. The recent large-scale island interconnection project in China has had to use expensive imported oil-filled cables because of the lack of 500kV ultra-high voltage cross-linked polyethylene submarine cables. The successful development of Zhongtian Technology's 500kV submarine optoelectronic composite cable product will fill the gap in the international high-voltage submarine cable industry.
According to the introduction of Prof. Xie Shuhong, Director of the China-Industrial Cable Research Institute, the new technology of Zhongtian Technology 500kV submarine composite optical fiber cable has practical engineering needs. The State Grid Zhejiang Electric Power Company plans to transform the electric engineering from Ningbo to Zhoushan and plans to apply it. New 500kV submarine composite optical fiber cable technology, including the laying of Zhenhai to Dapeng Mountain submarine transmission cable, and through the overhead line through the Jintang Island, the booklet island and other islands to the Zhoushan Island Island, opening up Zhoushan and the mainland network of the second channel.
Relevant data show that China's offshore/offshore areas are rich in resources suitable for offshore wind power development. The available wind energy resources are over 750 million kilowatts, of which about 250 million kilowatts are offshore and about 500 million kilowatts offshore. The construction of “resource-saving and environment-friendly†offshore wind farms has just started, and a large number of submarine optical cables are needed to transport the power of offshore wind farms to shore. Experts pointed out that China will usher in an upsurge in offshore wind power construction, and the transmission of offshore power to shore will be encouraged by the state if conditions allow.
Zhongtian Science and Technology successfully developed and produced a three-core large-length 220kV submarine optoelectronic composite cable system, especially for large-length cross-linked, large-length core degassing, cable technology technology research, large-section water-blocking process, enhanced equipotential Fiber optic units and their factory joints are technologically advanced and innovative. Zhang Jianmin, chief engineer of Zhongtian Scientific Cable Co., Ltd., said that the successful development of the three-core large-length 220kV submarine optoelectronic composite cable system has formed a good design, production and inspection system, and trained a group of professionals.
The single-core 500kV and three-core 220kV submarine cables developed by Zhongtian Science & Technology Marine Cable have broken through key technical problems such as large length, large weight, high strength, long degassing time, and waterproof, antiseptic, and photoelectric integration systems. Yang Yingjian, senior expert in high-voltage cables, said: Zhongtian Science and Technology Marine Cable Co., Ltd. has developed a large-length, high-voltage cross-linked polyethylene submarine photoelectric composite cable production technology research, the formation of a large cross-section conductor with independent innovation Performance water resistance technology, large-length cross-linked polyethylene insulation extrusion, degassing and finished product production technology, factory soft joints and other technologies, product comprehensive technical performance has reached the international advanced level.
Xue Jianling, general manager of Zhongtian Technology Cable Co., Ltd., stated that as a high-end marine equipment company, the company will further intensify innovation, realize the joint development of the ocean and internet economy, serve the needs of national energy construction and information security, and provide national security and social security. Provides functions such as logistics information, ocean data link, external information interconnection, intelligent long-distance monitoring of resource development, and protection of national maritime rights and interests, and continues to make new contributions to China's marine economic development.
The appraisal meeting will be jointly organized by China Electricity Council and Jiangsu Provincial Economic and Information Commission. State Grid Electric Power Research Institute, South Network Electric Power Research Institute, Shanghai Cable Research Institute, National Wire and Cable Quality Supervision and Inspection Center, Electric Power Industry Electric Equipment Testing Center, China Electric Power Research Institute, and Electric Power Design and Users from across the country The experts and leaders participated in the appraisal meeting.
