Problems solved by technology

[0004] The poles and towers used in electric power engineering are generally arranged in a triangle, and the corridors occupy a large area. Especially when entering a densely populated area, if measures are taken to adjust the direction of the line and avoid houses, the length of the line will be significantly increased and the project cost will be increased.

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The 3V series iron tower of the present invention comprises a tower base 1 and a U-shaped fork 2 arranged on the tower base 1. In the U-shaped fork 2, three sets of V-shaped strings 3, namely upper, middle and lower, are arranged side by side at intervals. High-voltage cables 4 are arranged at intervals on the V-shaped string 3 .

[0021] Further, in order to design rationally, prevent wires from deicing and jumping and limit cable galloping, the V-shaped string includes V-shaped non-conductive brackets 5, and a plurality of insulators 6 are connected in series on both sides of the V-shaped non-conductive brackets 5 , a high-voltage cable 401 passes through the bottom of the groove of the V-shaped non-conductive bracket.

[0022] Further, in order to prevent mutual interference and prevent wires from deicing and jumping, flang...

Abstract

The invention provides a 3V bunch iron tower and a construction process thereof. The 3V bunch iron tower is characterized in that the 3V bunch iron tower comprises a tower footing and a U-shaped supporting fork arranged on the tower footing; three sets of V-shaped bunches arranged in parallel in a paced mode are arranged in the U-shaped supporting fork; and high-voltage cables arranged on the V-shaped bunches in a spaced mode. Design of the high-voltage cables can be effectively controlled, cross arms are omitted, and the structure arrangement is optimized, so that the purposes of ensuring the structure stability and saving tower materials are achieved; and the requirements for windage yaw and waving under various working conditions are met without regard to the horizontal displacement.

Description

[0001] Technical field: [0002] The invention relates to a 3V series iron tower and its construction technology. [0003] Background technique: [0004] The poles and towers used in electric power engineering are generally arranged in a triangle, and the corridor occupies a large area. Especially when entering a densely populated area, if measures are taken to adjust the line direction and avoid houses, the length of the line will be significantly increased and the project cost will be increased. [0005] Invention content: [0006] The purpose of the present invention is to provide a 3V series iron tower and its construction technology. The 3V series iron tower has a simple structure and a reasonable design, which is beneficial to compressing the width of the line corridor and reducing the construction cost. [0007] The 3V series iron tower of the present invention is characterized in that: it includes a tower base and a U-shaped fork arranged on the tower base, and thr...
