Description

Bindless cover {BINDLESS COVER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binderless cover for coupling a high-voltage cable to an insulator, and more particularly to a binderless cover configured to allow an operator to easily and quickly work using a work clamp.

Generally, in order to fix the high voltage cable located at the upper part of the electric pole to the insulator, the structure of the insulator upper part is changed to a structure in which the high voltage cable can be inserted or fixed, or the high voltage cable is fixed to the insulator through a separate fixing member.

However, this is in the form where the operator directly performs the fixing work close to the high-voltage cable and is not suitable for the work instructions prescribed to work at the bottom of 2 meters of the high-voltage cable recently for the safety of the operator.

On the other hand, the size of the upper end portion of the insulator is slightly different in size (thickness, size, etc.) from manufacturer to manufacturer, and a cover for fixing the high-voltage cable to the insulator is also required to be manufactured in accordance with the size of the upper end portion of the insulator.

Accordingly, studies have been made on a cover for fixing the high voltage cable to the insulator using the work clamp.
