Description

Line post insulator for construction of distribution line and distribution line construction method using the same {line post Insulator for binding electric wire}

 The present invention relates to a line post insulator for a distribution line construction and a method for laying a distribution line using the same, and more specifically, to couple the mounting holder of the distribution line to the top of the insulator body in which the shaft coupling member is installed, and having a structure opposite to the mounting holder. The present invention relates to a line post insulator for a distribution line construction and a distribution line construction method using the same, in which a distribution line is mounted between a mounting holder and a holder for fixing.
