Description

Guide device for cable transmission {GUIDE DEVICE FOR CABLE SEND-OUT}

This disclosure relates to a guide device for cable delivery.

The construction of power cables used for power transmission and distribution uses steel towers erected at regular intervals on the ground or utility tunnels placed underground. Meanwhile, not only power cables but also cables for various purposes are installed inside the building. These cables are laid on rails that are installed along a predetermined route.

The cable delivery device is configured to send out a cable wound around a cable drum, move it along a rail, and install the delivered cable on a rail on a predetermined installation path. Cable guide devices are installed at regular intervals along the installation path so that the cable transmitted by the cable transmission device can move smoothly along a predetermined path. Additionally, since the installation path includes not only a straight path but also a curved path, a cable guide device can be installed even at a location where the path changes. Generally, the cable guide device is fixedly installed on the rail.
