On September 1st, with the global Energy Internet European Research Institute (European Academy) leading the design and development of  500 kV flexible DC cable accessories through all type tests, global Energy Internet Research Institute Co., Ltd. in the field of flexible DC power transmission, another key equipment research and development made a major breakthrough. Master key technologies of environmental protection flexible DC cable accessories of 500 kV silicone rubber technical route.

    Dc cable accessory is the key equipment for HVDC cable, converter station and cable connection. Its development involves many technical problems such as material, machinery, manufacturing and installation, and is one of the main bottlenecks of HVDC cable technology research and development. At the same time, in order to meet the increasingly strict requirements of green environmental protection, THE institute aims at the research and development of cable accessories based on silicone rubber materials. Compared with epDM technology, this technology has the advantage of green environmental protection, but it also increases the difficulty of design and process, and has not been able to break through the application of this technology in 500 kv voltage grade equipment in the world.

   The European Court created a new technical route, broke the foreign manufacturers silicone rubber technology is not suitable for 500 kV high voltage DC cable accessories judgment. As an important part of the innovation system of science and technology corporation, the European court will continue to play a good talent advantage, no distractions, difficult to overcome, to solve key technological research field application base and strategic foresight "their" problem, seize the commanding heights innovation, for the construction with Chinese characteristics of international leading energy Internet companies contribute new wisdom, create new results.
