Abstract

PROBLEM TO BE SOLVED: To secure or remove a cable to or from an insulator with one-touch by providing a cable intermediate supporter with an insulator holding section which has a cable inserted in it and is to be set in a head of the insulator and holds the insulator temporarily and an insulator securing section which secures the supporter to a jaw of the insulator by an operation bar for hot stick engineering method. SOLUTION: A pair of stoppers of an intermediate supporter 1 are set on an open end of the intermediate supporter 1 by an insulating operation bar and a gripping tool. With external parts at both ends of a cable insertion hole or parts of the stoppers being gripped, the supporter 1 is carried in the air to a point where a preliminarily suspended cable 'a' is to be secured to an insulator and then the cable 'a' is loosely inserted into a cable insertion guide and an insulator insertion hole is set in a head of an insulator 'b' to push the intermediate supporter into the insulator 'b'. Then, one of the stoppers is moved toward a jaw 'd' of the insulator 'b' and is inserted into a locking hole by a locking pin. The other stopper is moved and locked in the same matter. In order to remove the stoppers, the locking pins are pushed out of the locking holes and the stoppers are moved back to the open end and a part of the intermediate supporter 1 is held, and then removed to be recovered.
