<p>PURPOSE:To improve workability and improve visual aspect for easy confirmation from the outside by incorporating a catenary wire in an electric cable and integrating them, and laying the cable with the laying work of the catenary wire, while to prevent staple and the like from touching the wire and to prevent the insulator around the wire from being compressed excessively. CONSTITUTION:A catenary wire 15 is burried in an insulator so that it may not touch wires 11-13. The wire 15 is arranged in parallel with the wires 11-13 and at the intermediate part 14'a between the wires of insulator 14' and the wire 15 a notched part is formed. At the intermediate part 14'a a fixed member is set in through a steple 50. The part 14'a is held by a clamp 60 and the clamp 60 is installed on the fixed member.</p> |
