There is an insulated trolley wire disclosed in the -101627 publication. This insulated trolley wire is constructed by covering a part of the outer periphery of a messenger wire with a conductor, and covering the sliding surface of the conductor with an insulating cover. The sliding surface of the conductor is a convex curved surface, and the current collector that slides on the sliding surface is formed into a concave curved surface.
However, there were problems in that machining the concave curved surface of the collector was complicated and the bonding force between the conductor and the messenger wire was weak.

In order to obtain good current collection with such an insulated trolley wire 1, it is necessary for the current collector 10 to always contact the conductor 15 under the same conditions, such as keeping the contact pressure of the current collector 10 constant. However, the conductor 15 and the insulator 14
The insulator 14 is manufactured by integral molding, and due to variations in molding, a portion of the insulator 14 may protrude from both sides of the exposed surface of the conductor 15, as shown in FIG. 14
a is its protruding portion. If the insulator 14 protrudes in this manner, the current collector 10 may ride on the protruding portion 14a of the insulator 14 as shown in FIG. 4, causing wire separation. If disconnection occurs, conductor 1
Sparks are generated between the conductor 15 and the current collector 10, and the surface of the conductor 15 or the current collector 10 becomes rough, shortening their lifespan.
