The ac field of the world's first new converter station in the three-terminal DC project has been electrified successfully

On May 4, the world's first three-terminal DC project - the Yunnan-Guizhou Interconnection Channel Project, the newly built Luquan converter station ac field was successfully started, and the south Network's highest elevation UHV converter station was successfully electrified.

Yunnan-guizhou Mutual Link Project, which was constructed by China Southern Power Grid ULTRAhigh Voltage Co., LTD., is China's first "two-end" to "three-end" DIRECT current transmission project, and the state's key west-east power transmission project during the 13th Five-Year Plan period.500 kV Luzhi converter station is the only newly built converter station in this project, with an altitude of about 2530 meters, and is the highest uHV converter station in China.The project will also be the 500 kV converter station with the shortest construction period in China, with only 15 months from "three connections and one level" to operation.

It is understood that the exchange site was successfully launched, and the production, operation and maintenance personnel completed 62 major and 756 minor operations with high quality all night long.The electrification range of the AC field includes 500kV AC field, 500kV AC filter busbar, transformer equipment and related protection, control, measurement and metering equipment.As the delivery station of Yunnan-Guizhou Interconnection channel project, this operation ensures the safe and stable operation of the equipment and power system in the communication field, which creates conditions for the debugging of the station system in the next step, and also lays a solid foundation for the whole project to ensure the "6.30" and strive to achieve the operation target of "6.15".

At present, the Yunnan-Guizhou Interconnection project has been completed. The overall progress of luquan Converter Station has been about 97%. The whole project is scheduled to be completed and put into operation by the end of June this year.After the project is put into operation, it will promote the consumption of surplus hydropower in Yunnan, promote the mutual aid and complementation of electricity in Yunnan and Guizhou, give full play to the standby benefits of inter-provincial power support, and further promote the coordinated development of east and west regions.

          Jiangsu Jinsanli Power Equipment Industrial Co., Ltd. was founded in 2001, Is located in the Guli street of Nanjing Jiangning Economic and Technological Development Zone.We are specializing in the production of UHV Transmission Insulators and Transmission Rubber Components. We maintian and continue to improve our product quality at the same time focus on research and development of new technology to meet the China and Overseas electricity market demand. We work together with the best Electrical Engineers in China and the Nanjing Univeristy Polymer Research Center to develop a new type of material for Transmission Line Insulators. .This is called the MODIFIED POLYETHYLENE(HDPE), unlike the ordinary polyethylene that is in the market now this is made up of new material to make a Hard Composite Type, High Insulation Performance, High UV Protection for longer life, Light Weight, Stronger Mechanical Strenght and Impact Resistance, Provide more superior moisture and contamination shedding because of the High Hydrophobic Property and a longer Leakage Distance and finally the Anti-Tracking Property that makes this product more efficient and make it quickly recognised all over the world.

         We passed ISO9001: 2015 quality management system certification, ISO14001: 2015 environmental management system certification and ISO18001: 2007 occupational health and safety management system certification. We are certified by the National Grid Product Technology in 2013, We won the title of Best Private Technology Enterprises in Jiangsu Province.  We officially become a National High-Tech Enterprises in 2016 because of our dedication and continous development on new materials for the electrical industry. And In 2017, We become the Leading Company in Nanjing for the Technology Research. Through the efforts of all staff, our company won the title of China's industry-university-research cooperation innovation demonstration enterprise in 2019.

         [Pragmatic innovation] this is our company motto. We work hard to developed and produced the best product for China's Power Transmission Industry and for Overseas Power Industry.
