なり、地絡や短絡の危険が生じる。There is a wiring method of so-called vertical wiring for wiring of electric wires installed between telephone poles. The vertical wiring is not wired in parallel with a constant interval in the horizontal direction as usual, but is wired in parallel with a constant interval in the vertical direction. By the way, when performing electrical work such as replacement of equipment on a power pole, there is a case where the work is performed by a bypass method so as not to cause a power outage in the vicinity. Since the bypass cable used in the bypass method hangs downward, there is no concern that the bypass cable will contact another electric wire if the electric wire is a normal horizontal wiring. However, if the wires are routed vertically,
The bypass cable is more likely to contact other wires underneath, creating the risk of ground faults and short circuits.
