Multi-prism steel pipe pole of power transmission line

Abstract

The invention relates to a multi-prism steel pipe pole of a power transmission line, belonging to steel pipe poles. The multi-prism steel pipe pole structurally comprises a master pole and a cross arm fixed on the master pole, wherein a bottom flange is arranged at the bottom of the master pole; the master pole is formed by connecting more than two sections of hollow tapered poles through a butt flange; a plug is arranged at the top of the master pole; a grounding electrode is arranged at the lower part of the master pole; the cross arm and the master pole are connected through a cross arm connecting plate; the cross arm connecting plate is fixed on the master pole; the cross arm and the cross arm connecting plate are connected through a bolt; and the cross section of the master pole is multi-prism-shaped. Compared with the prior art, the multi-prism steel pipe pole of the power transmission line, disclosed by the invention, is convenient for installation of the cross arm and fixed easily; the master pole is in a sectional structure and has the characteristics of easiness in machining, convenience for construction, operation safety and reliability, less maintenance amount, and thelike; and therefore the multi-prism steel pipe pole has favorable popularization and application values.

Description

technical field [0001] The invention relates to a steel pipe pole, in particular to a multi-edge steel pipe pole for transmission lines. Background technique [0002] Electric power transmission line steel pipe pole is a kind of equipment support widely used in urban and rural power grid transmission lines. The load requirements of the large cross-section conductors of the loop and the strength requirements of the corner rods without guy wires are widely used. With the continuous and rapid development of the national economy, the demand for electricity is increasing, especially at the peak of urban network transformation, the market demand for steel pipe poles for transmission lines is increasing day by day, and will continue in the future market look good. [0003] The steel pipe pole of the transmission line currently used, the crossarm is directly fixed to the main pole, which is difficult to install and not easy to fix; in addition, the main pole is an integrated struc...
