Method of producing arc extinguishing electrodes for spark gaps, and electrodes obtained

摘要

Inside an insulating sleeve 5 held momentarily by removable clamps 2 on a heating plate 1, is poured an appropriate quantity of an arc extinguishing material. The earth thus formed is surmounted by a metal stud 7 which is pushed downwards by a heating pin 8 to obtain by compression and heating a pad 6 linked through the stud 7 to an axial rod 9 forming a support and connection terminal. <IMAGE>
