Yanchaojuneng Completes VPI of Stainless Steel-Jacketed Superconducting Prototype Coil for Stellarator
Recently, Yanchaojuneng (Shanghai) Technology Co., Ltd. completed vacuum pressure impregnation (VPI) of a next-generation stellarator stainless steel-jacketed three-dimensional shaped superconducting prototype coil. Previously, the prototype coil had completed two core processes: three-dimensional precision winding and ground insulation wrapping. The completion of VPI signifies that the company has established an autonomous process chain from coil winding and forming, insulation wrapping, to integrated insulation curing. The stellarator is an important device type for steady-state operation in the field of controlled nuclear fusion, capable of reducing the risk of major plasma disruptions. Three-dimensional shaped superconducting coils are the core components for building the magnetic field that confines plasma in a stellarator. Public information shows that Germany's W7-X stellarator uses aluminum alloy jackets...
