High-strength and low-weight electric power pole tower

Abstract

The invention belongs to the technical field of electric power pole towers, and particularly relates to a high-strength and low-weight electric power pole tower. The high-strength and low-weight electric power pole tower comprises a fixing part located at the bottom, a transition part located on the upper portion, and a reinforcement cage located inside; the fixing part is a cement pipe wrapping the lower portion of the reinforcement cage; the transition part is a hard plastic pipe wrapping the upper portion of the reinforcement cage; a plurality of vertical strip-shaped groove openings are evenly distributed in the portion, making contact with the hard plastic pipe, above the cement pipe; a plurality of strip-shaped bulges matched with the strip-shaped groove openings are evenly distributed on the lower portion of the hard plastic pipe; and a metal fixing ring for storing an electric wire frame is arranged at the top of the transition part. The defects of the prior art are overcome, the mode that cement and plastic are combined is adopted, the strength of the pole power is guaranteed, the overall weight of the pole power is also lowered, meanwhile, the metal fixing ring structureis adopted at the top, thus the strength of the fixing position for storing the electric wire frame is guaranteed, the structure is simple, the manufacturing cost is low, and the application range iswide.

Description

technical field [0001] The invention belongs to the technical field of power poles and towers, in particular to a high-strength and low-weight power poles and towers. Background technique [0002] The pole tower is one of the basic equipment in the overhead power distribution line. According to the materials used, it can be divided into three types: wooden poles, cement poles and metal poles. Cement rods have the advantages of long service life and small maintenance workload, and are widely used. The most used cement rod is the tip rod, the taper is generally 1 / 75, which is divided into ordinary reinforced concrete rods and prestressed reinforced concrete rods. [0003] Wherein the existing cement pole tower has gradually been eliminated due to its relatively heavy weight, so a new type of high-strength pole tower is urgently needed to meet the demand of the market. Contents of the invention [0004] The purpose of the present invention is to provide a high-strength and ...
