Abstract

The invention discloses a power transmission line steel tube tower which comprises a steel tube tower trunk, wherein multiple branch line cross arms are arranged on the steel tube tower trunk; the tail ends of the branch line cross arms are connected with branch lines through strain clamps; a mainline cross beam is also arranged on the steel tube tower trunk; the mainline cross beam and the branch line cross beams are arranged in a staggered manner; and arm of the mainline cross arm is connected with a suspension clamp for suspending the mainline. Through the power transmission line steel tube tower disclosed by the invention, external power-cut time is short in construction; the line hardware materials are few; the construction personnel and labor amount are reduced; and equipment used at site is reduced.

Description

technical field [0001] The invention relates to a steel pipe tower for transmission lines. Background technique [0002] At present, the steel pipe tower of the conventional transmission line is composed of the steel pipe tower trunk and several branch line cross-arms arranged on the trunk. The general specific implementation steps of the connection of the main line are as follows: [0003] 1. To anchor the conductors in the front and rear trunks, 12 Φ16 steel wire ropes need to be clamped with clamps, and the conductors are anchored on the ground anchors; [0004] 2. Pull the wire with a motorized winch, then break the wire and loosen it to the ground; [0005] 3. Make hydraulic connection tension clamp; [0006] 4. Tighten the line, hang the line, remove the anchor line, steel wire rope, etc.; [0007] 5. Make jumper connection; [0008] The manpower and material resources required are roughly as follows: [0009] There are 16 workers, 2 motorized winch mills, 2 tens...
