Recently, from the company's ultra-high voltage plant came the good news, the first batch of large length 110kV seamless smooth aluminum sheath power cables, after strict factory inspection, all qualified, ready for shipment and delivery, with a total length of 11.48km. the batch of cables will soon be used in the Zhejiang Jiaxing Mountain Eagle Paper Liangxin Electric Air Chemistry 110kV line renovation project.

 

 

The batch of cables from the technical communication, order determination, product manufacturing and other aspects of the experience of more than two years, and Jiaxing Hengguang Electric Power Design Institute, the Department of Operations and Maintenance, the Ministry of Construction and other departments of a number of technical exchanges and communication, and finally won the bid for the project; the product in the continuous production, extrusion of the aluminum sheath, roller shrinkage, hot melt adhesive + sheath + conductive layer of the three-layer co-extruded, the production of the hauling head and other aspects of the project, to overcome a number of technical difficulties. In the process of large-length mass production, we received great assistance from the engineers and technicians of Shanghai BWE Company, and also encountered a variety of technical bottlenecks that had never been encountered in the production process. However, with the joint efforts of the staff and technicians of the UHV plant, many technical bottlenecks were solved, and the technical accumulation and leap from small batch production to large batch production of large length was realized, with the length of a single cable reaching 1,930m, which gave full play to the intelligence of the staff from the upper level to the grassroots level of the company, and it is also the first innovative product that was launched and applied after the company landed on the Bejing Stock Exchange on July 12, which is the first time for the company to promote the domestic and overseas power system and to promote the international power supply system and to promote the international power supply system. This is also the first innovative product launched and applied after the company landed on the NSE on July 12. It lays a foundation for the company to promote the application of seamless smooth aluminum sheathed cables and large-length cables in the electric power system, which is the first of its kind at home and abroad, and to solve the technical problems in the industry.

 

The company designed and developed 110kV seamless smooth aluminum sheath cable has a number of invention technology, for the first time to achieve seamless aluminum sheath extrusion and hot melt adhesive + outer sheath + conductive layer of three-layer co-extrusion of continuous production. We have designed and developed a new production process for seamless and smooth aluminum jacket cable, eliminating the risk of internal protrusion of argon arc welding seam, and realizing the quality optimization of seamless and smooth aluminum jacket.

 

Seamless smooth aluminum jacket and cable shielding surface overall contact, can prevent the cable internal buffer layer contact poorly produced by the phenomenon of galvanic corrosion; cable structure is compact, small thermal resistance, heat dissipation is good, can improve the current-carrying capacity; aluminum jacket and the core as a whole, can improve the side impact and resistance to lateral pressure; and wrinkled aluminum sheath cables, the product has a small outer diameter, less consumables, large capacity, long loading tray, excellent performance, easy installation and bending, safe operation, etc., can be widely used in the cable production, and can be widely used in the cable industry, and can be used in the cable industry. Compared with wrinkled aluminum sheathed cable, the product has the advantages of small outer diameter, less consumables, large capacity, long loading disk, excellent performance, easy installation and bending, safe operation, etc., and it can be widely used in high-voltage AC cable lines of electric power system.
