Recently, news came from the China Power Cable Technology Exchange held every four years: The 110kV composite smooth aluminum sheathed cable newly developed by ZJCG Cable Technology Group was displayed. Jin Jinyuan, the company’s vice president of technology and a professor-level senior engineer, was working on new materials, New technology and new process will give a speech in the sub-venue, and give a thesis explanation of "110kV composite smooth aluminum sheathed cable key production process design", and won the conference excellent paper award.
From October 22 to 23, the "Eleventh China Power Cable Technology Exchange Conference" organized by the China Electric Power Research Institute was held in Zhuhai, attracting nearly 500 people from the State Grid, China Southern Power Grid, scientific research institutions, and manufacturing companies. Leaders, experts and scholars participated.
This process realizes the continuous production of aluminum sheath welding and outer sheath extrusion for the first time, improves the compactness of the buffer layer structure, and has a small outer diameter. Compared with the corrugated aluminum sheath cable of the same specification, not only the manufacturing cost is lower, but also the increase The technology is at the international leading level.
Research on the performance of smooth aluminum sleeves abroad has accumulated a lot of design and use experience. Due to the limitation of the laying environment and conditions, almost all of the wrinkled aluminum sleeve structure is adopted in China. With the development of the industry, the advancement of technology and the attention of relevant departments, the laying environment and construction equipment of China's cables have been greatly improved, which provides good conditions for the application of smooth aluminum sheathed cables. ZJCG took the lead in successfully developing smooth aluminum sheathed cables and has been applied in many domestic power supply companies.
