POWER TRANSMISSION LINE SUPPORT AND METHOD FOR ITS INSTALLATION

摘要

construction of aerial power transmission lines. SUBSTANCE: the support is a structure in the form of a tetrahedral truncated pyramid, formed by inclined latticed struts hinge- resting on foundations and interconnected by a hinge overhead. A cross-arm - lattice beam is positioned in the upper part of the pyramid between the struts. The extreme phases are attached to the cantilever sections of the cross-arms, and the middle phase - to the middle of the cross-arm. The wires and overhead ground- wire cables are fastened by the ground and lifted together with the cross-arm. EFFECT: reduced labour cost and simplified installation of power transmission line. 2 cl, 1 dwg
