Description

Bracket for fastening arrester using indirect live wire method}

The present invention relates to a bracket for installing a lightning arrester on a telephone pole, and more specifically, a bracket and a fixing bolt part are integrally provided, and an insulation hanger for mounting an electric wire is integrally provided, so that indirect live wire using a smart stick is easy. The present invention relates to a bracket for fastening a lightning arrester applying an indirect live wire method that enables quick and easy indirect live wire work to prevent safety accidents of workers in advance.

In general, when installing a lightning arrester on a telephone pole, a separate bracket is used to install it on the telephone pole.

In the form of a general bracket, it is a method that can be fixed by connecting two fastening sticks that can fix the arrester with two fastening bolts and two nuts. There is a problem that you need to prepare.

At this time, due to the small bolts and nuts, an electric shock accident occurs while the operator removes the insulating gloves and assembles and tightens, and a problem such as a power outage occurs, causing a problem in power supply.

In addition, the work time is delayed, the fatigue of the worker increases, and a problem that is difficult to recover quickly in case of a power failure occurs.

Relatedly, in Prior Document 1 (registered utility model 20-0334700 integrated bracket for installation of a lightning arrester for distribution), a configuration in which the parts of the bracket are simplified to facilitate operation is disclosed.

However, in Prior Document 1, since the bolts must be installed individually, they must be installed in a direct live wire method in which the operator directly fastens with their hands, and in fastening the bolts, problems such as fall or loss of the bolts occur due to the individual installation.

In addition, the work time is delayed, causing a problem that a long recovery time in case of a power failure occurs.
