Double-circuit and double-T-connection steel pipe pole

Abstract

The invention discloses a double-circuit and double-T-connection steel pipe pole which comprises a pole. The pole is sequentially provided with four layers of double-side cross arms on a main circuit from top to bottom, ground wire cross arms are arranged on a first layer and are used for hanging ground wires, and upper-layer conducting wire cross arms, middle-layer conducting wire cross arms and lower-layer conducting wire cross arms are sequentially arranged on a second layer, a third layer and a fourth layer and are respectively used for hanging upper-phase, middle-phase and lower-phase conducting wires of the main circuit; the pole is further provided with at least three cross arms on a double-T-connection circuit, and the cross arms on the double-T-connection circuit sequentially include branch ground wire cross arms, branch conducting wire upper-layer jumper cross arms and branch conducting wire lower-layer jumper cross arms and are perpendicular to planes where the four layers of double-side cross arms are located.

Description

technical field [0001] The invention relates to the field of erection of high-voltage transmission lines, in particular to a double-circuit double-T connected steel pipe pole. Background technique [0002] With the rapid development of the economy, the scale and density of transmission lines are also increasing. In order to save land resources, the main lines of high-voltage transmission lines are often erected with double circuits on the same tower (pole), and the branch lines T are connected to the main line. There are generally two ways to realize the T-connected double-circuit overhead line: one is to build a base double-circuit cable T-connected to the steel pipe pole under the existing double-circuit overhead line, and then use the cable climbing pole to T-connect the circuits on both sides; Under the double-circuit overhead line, build a new base of conventional double-circuit double-T connection steel pipe pole, and then use the jumper wire to jump to the T-connectio...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the increase in the gap height of the cross-arm of the double-circuit double-T connected steel pipe poles in the prior art, which continuously increases the upward pulling force between the wires between the steel pipe poles and the difficulty of project implementation and the increase in project cost. big flaw
