18. A method of manufacturing a high-voltage surge arrester, comprising:
-
selecting a desired length for each of a plurality of metal oxide varistor (MOV) bars based on a desired operating voltage of the surge arrester; selecting a desired number of MOV bars to include in the plurality of metal oxide varistors based on a desired current rating of the surge arrester; forming the desired number of MOV bars having the desired length to provide the plurality of metal oxide varistor (MOV) bars; arranging the plurality of MOV bars so that each of the MOV bars extends lengthwise from an electrically conductive first terminal of the surge arrester to an electrically conductive second terminal of the surge arrester and electrically contacts the first terminal and the second terminal; placing a heat conducting material contacting the arranged MOV bars; and securing the arranged plurality of MOV bars to provide the surge arrester having the desired operating voltage and the desired current rating. - View Dependent Claims (19, 20)
