PROBLEM TO BE SOLVED: To manufacture a new type compound cable for multiple wiring by forming a compound cable of plural power cables having a different finished outer diameter, and providing projections in a power cable having a small finished outer diameter, and binding them with a rushing wire. SOLUTION: A power cable 3 with projections, which has a small finished outer diameter, is arranged between a messenger wire 2 and a power cable 4 having a large finished outer diameter, and the projections 3a are projected to both outsides. The projections 3a are finished to a shape, which abuts on the inside of an inclined part of a rushing wire 1 wrapped around the messenger wire 2 and the power cable 4. The power cable 3 with projections is constrained by the rushing wire at the projections 3a, and bound with the power cable 4 and the messenger cable 2. With this structure, a new type cable to be used for multiple wiring and having excellent economic merit, which is formed by compounding plural power cables having a different outer diameter, is obtained. |
