METHOD FOR ATTACHING SPACER FOR MULTIPLE CONDUCTORS

摘要

PROBLEM TO BE SOLVED: To provide a method for attaching a spacer for multiple conductors which requires no correction by a worker on board a pendent cage after the attachment. SOLUTION: When intending to attach a spacer onto multiple electric wires 10 stringed with a space to a vertical direction, the computed value of the catenary angleθ0 of the electric wires at attaching positions of each spacer is obtained based on a slackness calculating formula. When the spacer is attached onto the electric wires with a pendent cage 7, the actual catenary angleθof the electric wires at attaching positions of the spacer is measured. Then, the spacer is attached onto each electric wire by shifting the attaching position P13 on the bottom wire 13a by a corrected amount R (to an attaching position Pb) obtained by a calculating formula R = Dtan (θ-θ0 (where D is the space from the top to bottom wires) against the right angle attaching position to the top wire 11a.
