Abstract
A disclosed method of repairing a shed portion of a composite insulator having a core portion, a sheath portion arranged on an outer surface of the core portion, and a plurality of shed portions projected from the sheath portion, includes the steps of, (1) cutting out the shed portion having defects from a portion thereof adjacent to the sheath portion, and connecting a new shed portion having the same shape as that of the cut out shed portion to the sheath portion at the cut out portion, or (2) cutting out partly said shed portion having defects, and connecting a repairing member to said cut out portion. Therefore, it is possible to perform the shed portion repairing operation without wasting the normal shed portions.
