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 W1 and the core wire 21 of another power supply wire 20-2 conducts to a voltage applied conductor cable W2. The power supply wires 20 having high tensile strength enables to suspend the electrical apparatus and also supply power thereto.
