Abstract
A method for vertically grounding and leading down form a center of a composite pole tower includes the following steps: extending a ground down-leading wire from a center of a ground wire cross arm which is made of metal and is positioned on top of the pole tower, wherein the ground down-leading wire is vertically leaded down to the earth form the center of the composite pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is extended from the center of the composite material and is directly connected to the metal pipe. The method utilizes the advantage of the insulating intensity of the wall of the composite pole tower and enhances the insulating intensity of the transmission line on impact of lightning. The ground down-leading wires are prevented from short-circuiting with the tower body of the composite pole tower, so that advantage of the insulating property of the composite material of the pole towers is realized. Since the ground down-leading wire is penetrated through center of the pole tower, so that the ground down-leading wires are not exposed and are prevented from destroying by external force. And also the method is easy and simple for application.
