Power supply wire, wire grip, electric appliance suspending device, and electric appliance suspending method

摘要

The electrical apparatus suspension unit 1 is provided with two power supply wires 20 - 1 and 20 - 2 by which the electrical apparatus 3 is conducted and suspended from the ceiling 5 . Each of the wires 20 is connected to the hung member of the electrical apparatus 3 at the lower end by the a lower holder 40 , and connected to the rail 9 laid on the ceiling 5 at the upper end by an upper holder 100 . The power supply wire 20 comprises a core wire 21 , an insulating layer 23 covering the core wire 21 and an outer layer 25 covering the insulating layer 23 . The core wire 21 of the power supply wire 20 - 1 conducts to a grounded conductor cable W 1 and the core wire 21 of another power supply wire 20 - 2 conducts to a voltage applied conductor cable W 2 . The power supply wires 20 having high tensile strength enables to suspend the electrical apparatus and also supply power thereto.
