The report pointed out that the self-developed positive and negative 800 kV, 4750 ANT HVDC converter valve prototype passed the new product technology appraisal recently, filling the gap in the core technology of China's HVDC transmission project. The ±800 kV, 4750 amp HVDC converter valve delivers up to 7.6 million kilowatts of transmission capacity, delivering the highest voltage and flow capacity in the world. The prototype was developed and manufactured by the China National Power Research Institute of China Power Grid for six years and has completely independent intellectual property rights. The advent of prototypes has made China the third country in the world after Switzerland and Germany to master the design, manufacture and test technology of UHV DC converter valves.
Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
China Electric Power Institute's independent intellectual property rights UHV DC converter valve passed the appraisal
On September 7, CCTV News Channel’s “News Live†section reported that the “±800kV/4750A UHV DC Converter Valve†independently developed by the State Grid Corporation of China Electric Power Research Institute passed the assessment of the National Energy Administration.
EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.
