<p>PROBLEM TO BE SOLVED: To provide exchanger and exchange method of a suspension insulator capable of exchanging an insulator regardless of a shape of an insulator cap.SOLUTION: A holder 21 is attached to an insulator cap 3 of an insulator 1 which is above the insulator 1 to be exchanged. An external surface of the insulator cap 3 and an inner shape of a liner 25 correspond each other. Therefore, downward force is applied to the holder 21, an inner surface of the liner 25 contacts tightly an outer surface of the insulator cap 3, and force is transmitted to the insulator 1. In addition, a top part of the holder 21 of the lower insulator 1 has a spacer 15 attached thereto. a stopper 15 is fixed to the insulator cap 3. Therefore, when force is applied to the holder 21 upward, the holder 21 (liner 25) is pressed against a lower surface of the stopper 15. Therefore the force of the holder 21 can be transmitted to the insulator cap 3 via the stopper 15.</p> |
