    Hello my friends... :)

    In overhead lines, the conductors are suspended from the tower and insulated from it and from each other by insulator strings.

    but i wonder why we linked a wire between insulator strings as shown in attached photos ..:confused:
    Does anyone know the reasons of it ??

    The insulators mechanically terminate the cables, the jumpers complete the circuit around the tower to convey the electrical power.

    Since the wire between towers needs to be replaceable and repairable, the splice connection at every tower makes for a convenient, deliberate splice point.

    They use two insulators when the wires come from different directions so that the strain can be more easily handled. If you notice in the picture, the two wires are at an angle to each other, not in a straight line.
