Description

  The present invention relates to, for example, a cable support member that is attached to an arm of a support that supports a self-supporting cable in which a suspension line and a cable body are integrated with an insulating covering member at a position separated from a utility pole (hereinafter, self-supporting cable). (Supported cables are sometimes referred to simply as cables.)

  In general, when this type of cable is routed between utility poles, if there are obstacles such as signs or roofs on the track, the support, for example, the leash is placed above the utility poles, ie above the obstacles. Is fixed. An arm that supports the cable at a position away from the obstacle is attached to the dispensing object in a direction orthogonal to the utility pole, and the suspension line is covered by a cable support member attached to the lower surface of the tip. Since the portion is sandwiched, contact with the obstacle is avoided.
