"Our company designed and developed 110kV cross-linked polyethylene insulated composite smooth aluminum jacket power cables using a series of key technologies such as double-gun welding, drawing shrinkage and sheath multi-layer co-extrusion and other continuous production, to solve the defects of the smooth aluminum jacket cable bending winding up bowing or wrinkled phenomenon, to improve the structural tightness of the cable, to ensure the quality of products ......".

Recently, in the second floor lecture hall of Zhejiang Pinghu St. Leger Hotel, an expert on the stage was making a summary report on the design and development of 110kV cross-linked polyethylene insulated composite smooth aluminum sheathed power cable. Gathered from the Chinese Academy of Engineering, the State Grid, the Southern Power Grid, China Electric Power Research Institute, Shanghai Cable Research Institute, Xi'an Jiaotong University, Shanghai Jiaotong University, Harbin Institute of Technology, Zhejiang Electric Power Company, more than 40 domestic top cable experts, the experts explained the new technology on the stage with great interest, have carried out the technical evaluation, we agreed that: your company design and development of the 110kV cross-linked polyethylene insulation composite smooth aluminum sheath power cables using double torch argon arc welding and sheath multi-layer co-extrusion technology, the first time to achieve the aluminum sheath welding and extrusion of the outer sheath of continuous production, improve the buffer layer structure of the tightness of the cable flow and water resistance, the product outer diameter is small, low manufacturing costs, the comprehensive performance of the technology has reached the international leading level.

Standing on the stage of the cable design and manufacturing experts, is the deputy director of the academician workstation of Zhejiang Chenguang Cable Company, professorial senior engineer Jin Jinyuan, he made a summary report on behalf of the workstation of the technical research and development. R & D 110kV cross-linked polyethylene insulated composite smooth aluminum jacket power cable, is based on the current demand for long-term safe operation of the power grid and the design of new high-voltage cable products. Through the precision design of the workstation technicians, the development of "pre-twisted conductor stranded into the cable production method, double-gun welding method, aluminum jacket shrinkage drawing technology, sheath co-extrusion precision technology," and a number of innovative technologies, not only to solve the smooth aluminum sheath cable bending bowing or wrinkled phenomenon, but also solved the operation of the cable will produce galvanic corrosion of the problem, but also improve the cable load capacity, and the cable will be able to provide the best service. Problems, but also to improve the cable capacity, the cable's long-term safety and reliability of the operation of the foundation has been laid, has a very good market prospects.

Zhejiang Chenguang Cable Company academician expert workstation was formed in 2010, based on the workstation in the cable technology innovation of a number of scientific and technological achievements, in 2011 was the title of Jiaxing municipal academician expert workstation, in 2012 became a provincial academician expert workstation in Zhejiang, in 2017 became a national model academician expert workstation. The workstation has 28 main R&D personnel, including 1 academician Qiu Aiqi of Chinese Academy of Engineering, 4 expert members of Xi'an Jiaotong University, and the company is equipped with a team member with 1 person of high level, 7 people of associate high level and senior technician, and 15 people of intermediate title. Since the establishment of the workstation, under the great importance of Zhu Shueliang, the chairman of the company, and the strong support of Qiu Aici academician, Xi'an Jiaotong University and Shanghai Cable Research Institute, the workstation has gathered innovative elements, adhered to the innovation as the driving force, and organized cooperation between the industry, academia and research institutes, which has played an important role in the service of technological innovation and sustainable development of the enterprise, improved the competitiveness of the enterprise, and cultivated enterprise technological talents, etc., and has achieved a better Economic Benefits.
