NEW-TYPE NON-SYMMETRICAL COPPER-GRAPHITE BASE AND SILVER BASE CONTACTORS FOR SAVING SILVER

    Graphical Abstract
    • Abstract
  • The present paper has studied the applications of Graphite-Copper non-symmetrical contactors in DW10-400 frame-type circuit breakers and analyzed their economic results. It has shown that ths performance of Graphite-Copper non-symmetrical contactors is superior to that of Ag-W self-matching contactors and completely satisfied for technical requirements of electrical products. As compared with conventional contactors silver by 50% can be saved.
