<p>PROBLEM TO BE SOLVED: To provide the lead-in structure of a service wire where an initial construction can be performed efficiently, an additional assembling work can be performed safely, easily, and inexpensively, and appearance cannot be sacrificed. SOLUTION: A low-voltage anchor insulator 20 for supporting each low- voltage power distribution electric wire path W and a messenger wire mounting metal fitting 40 for supporting the messenger wire M are provided at a perpendicular arm metal 10, a branch electric wire 51 is provided in an isolated space S between the perpendicular arm metal 10 and the electric post P, a branch source wire 51 of the branch electric wire 51 is connected to the low-voltage power distribution wire path W, and one edge of a service wire 30 that is attached to the messenger wire M being supported by the above mounting metal fitting 40 is connected to either unused one out of branch destination wires 51b, 51c, 51d, 51e, and 51f of the branch electric wire 51 every time when the service wire is expanded newly.</p> |
