Description

 FRP Insulation Cross Arm and Tightening Structure of Bracket for Cutout Switch Combining with It}

The present invention relates to a method of fastening a reinforced plastic (FRP) insulation support and a fastening structure of a bracket for a cut out switch (COS) coupled thereto. More specifically, a fastening method and structure for easy attachment and detachment are provided by forming a hole for penetrating the bracket on the insulating support, mounting a COS coupling bracket on the front, and fixing the bracket by fastening the bracket fixing screw part from the rear. It is a technique to do.

The insulation support for installing a cut-out switch (COS) on a normal telephone pole was made by fastening a bracket and insulator for iron COS to a pipe made of square iron. Recently, to secure insulation and reduce weight, a square pipe made of FRP is used by combining a bracket for COS made of glass fiber reinforced plastic (GFRP) made of sheet molding compound (SMC) or bulk molding compound (BMC). .

     As a related art, the following patent document 001 discloses a “manufacturing method for light-duty for telegraph poles” (see FIG. 1). However, this is because the brackets that are combined with the FRP support are assembled in a permanently fixed manner using fixing pins and adhesives, which causes many difficulties in transportation and installation due to the protruding brackets. In addition, since all the brackets are manufactured in a fixed state, it is impossible to selectively install the brackets in the field, and even in the case of partial breakage, the assembly of the support must be replaced.

     In addition, the following patent document 002 discloses a "manufacturing method for light buff for whole body cast". However, this is an extruder that extrudes the body 10 of a square pipe with the extruder of FRP, which penetrates the upper and lower sides of the body cut to a certain length, and penetrates both sides of the first core and the square pipe fixing the cutout switch. It is made by using 2 cores, filling the foamed urethane with the remaining parts where the 1st core and the 2nd core are sandwiched, and blocking only the left and right sides of the square pipe body. There are problems such as increase in manufacturing cost.

Therefore, it is easy to transport and install by simplifying the fastening and disassembly of the insulation support and the bracket to a structure that can be easily performed even at the installation site, and it is possible to develop a technology that can quickly respond to the situation by fastening the bracket selectively according to the situation of the site. The need for the situation is desperate.
