| Abstract: | This paper deals with the engineering design and fabrication of the OH coil for NSTX.The coil is wound with double-wire winding and the 8 sub-windings of four layers are electrically connectedin series.The sub-windings are water cooled in parallel by 8 individual cooling paths.The coil with double-wire winding has the characteristics of short cooling paths and good cooling result.A new processing technology is adopted for vacuum pressure impregnation of the OH coil.The coil after vacuum pressure impregnation has the same electrical and mechanical properties.The coil temperature and calculation of the velocity of cooling water flow are also given in the paper. |
