On November 3, 2018, the Banquet Hall of Jinmao Luxury Collection Hotel, Meixi Lake, Changsha, Hunan, and the new product and new technology exchange meeting of 500KV AC/DC cable accessories of Changxuan Electric Technology Co., Ltd. was held. More than 100 people from China's power industry experts and industry guests gathered to witness this event.
With the development of many EHV, long-distance and heavy-duty transmission projects in China, there are more and more substations with 500kV or higher voltage levels. At the same time, due to the continuous expansion of the city scale, the urban electricity load is increasing, using 500kV. As the voice of urban transmission lines is getting louder and louder, because overhead lines need to occupy a large space and have a great impact on the surrounding environment, EHV cable lines are increasingly used in power station outlets and urban power grids as high-voltage cable lines. The required component – the demand for ultra-high voltage cable accessories is also growing.
At present, although 500kV cable lines are put into operation in China, a large number of 500kV cable accessories need to be imported from abroad. On the one hand, we have to spend a lot of foreign exchange to buy foreign cable accessories at high prices, and often suffer from installation, operation and maintenance technologies. The restrictions have affected the normal operation of China's power supply system; on the other hand, with the successful development of domestic EHV cables, but because there is no matching domestic cable accessories, in many project bidding, foreign cable companies use their attachment technology. Restricting domestic cable manufacturers to participate in competition, this situation has seriously affected the promotion and application of China's EHV cables, cable accessories have become a bottleneck in the development of the cable industry. Therefore, the cable localization products, especially the localization of HV and EHV cable accessories, are in line with national interests.
The 500kV series cable accessory products not only have broad market application prospects, but also have significant social benefits, and are also the company's key research and development projects. After all kinds of difficulties, the company has finally developed a series of cable accessories such as 500kV porcelain sleeves, composite casing terminals, intermediate joints, GIS terminals, etc., and contributed to the development of China's EHV voltage cable industry.
The appraisal opinion of CEC Jianpin [2018] No. 166 and No. 167 "New Product Appraisal Certificate" is "the appraisal committee unanimously believes that the 500kV cable accessory products have reached the international advanced level and agreed to pass the product appraisal, which can be mass-produced", " The appraisal committee unanimously agreed that the 525kV (525kV) DC cable accessory product technology has filled the domestic gap and reached the international advanced level, and agreed to pass the technical appraisal.
At the exchange meeting, Mr.Zhengyuan Yu, the former chairman of the company, gave a speech to welcome the experts and guests present at the meeting. He said: The company's development always follows and shoulders the mission of “connecting global cable and lightening every family”, adhering to the principle of “integrity, pragmatism, Innovate and enhance the spirit of service, pool resources, create value, achieve employees, and contribute to society. We will meet new challenges under the new normal, seize new opportunities, achieve new development, vigorously promote strategic cooperation with all parties, and innovate the development model of enterprises. We sincerely hope to cooperate with new and old friends from all walks of life in good faith, hand in hand, and achieve win-win development!
Mr. Tao Yu, Chairman of the Board of Directors, expressed his gratitude to the experts and guests present at the meeting. "The success of this exchange meeting is inseparable from the help, trust and support of experts, professors, colleagues and friends."
Taking this exchange as an opportunity, the new journey of long cable technology has already set sail, and we are full of confidence for the future.
