<p>PURPOSE:To enable operability to be improved by fixing and placing a cable spacer with an inner diameter which is slightly larger than an outer diameter of an electric wire within a cable tray previously at a proper gap, by mounting a lead-in cover with a streamlined tip part to a tip of the lead-in electrical wire, and by leading the electric wire into a cable tray with a cable spacer from the tip part. CONSTITUTION:A cable spacer is fixed and installed within a cable tray previously with a proper gap. In this case, an inner diameter of the cable spacer needs to be larger than an outer diameter of an electric wire but this gap should be minimized. Thus, for enabling an electric wire 7 to be lead in easily, a pulling eye 11 is mounted to a tip of an electric wire 7, a lead-in cover 12 where a tip part 12a is in streamline shape is provided at the outside, and it is inserted into the cable spacer with this lead-in cover 12 as a tip. It is desirable that an outer diameter of the lead-in cover 12 is slightly larger than an outer diameter of the electric wire 7, thus enabling the electric wire to be led in easily and operability to be improved.</p> |
