Description

  The present invention relates to an insulating yarn for indirect hot wire construction. In particular, the structure of an insulating yatco for indirect hot-wire construction that can easily change the azimuth angle at which the gripping claws protruding from a pair of opening and closing gripping arms provided at the tip of the insulating operation rod close to each other based on the direction in which the insulation operation rod extends About.

  There are two types of hot-line work that performs high-voltage distribution lines without power interruption: direct hot-wire method and indirect hot-wire method. In the direct hot wire construction method, workers wear protective equipment such as high-pressure rubber gloves and perform power distribution work by directly touching the high-voltage distribution line that is energized. On the other hand, the indirect hot wire method allows the operator to perform power distribution work without directly touching the high-voltage power distribution line that is energized using an insulating operation rod (hot stick) or the like.

  In general, an insulating operation rod is composed of a long operation rod and a power distribution work tool (hereinafter referred to as a tip tool) attached to the tip of the operation rod. And the insulation operating rod is comprised so that a front-end tool can be replaced | exchanged according to the work objectives, such as holding | griping or cutting | disconnecting a high voltage distribution line.

  As an insulating operation rod for gripping such a remotely disposed high-voltage distribution line, an insulating operation rod for remote gripping that can open and close a pair of gripping arms provided at the tip of the insulating operation rod by hand operation, so-called “insulation” Yatko is known. In addition to the operation of gripping the electric wire using this insulating Yatco, the operation of covering the electric wire with a protective tube, the operation of removing the crow's nest nested in the electric pole, and the like are performed.
