Abstract

The invention discloses a 110 kV cathead type composite cross arm tower comprising a set of middle-phase composite cross arms, two sets of edge-phase composite cross arms, tower window support arms, two sets of steel ground wire supports and an angle steel tower body. Specifically, the middle-phase composite cross arms are fixed to the inner sides of the two tower window support arms through towerframe end connection pieces, the edge-phase composite cross arms are arranged on the outer sides of the two tower window support arms, and the ground wire supports are fixed to the upper sides of thetwo tower window support arms. Except the middle-phase and edge-phase composite cross arm structures, all the other structures are angle steel or steel connection pieces. On the basis of a traditional angle steel power transmission tower, the main body form of the tower body is not changed, and the upper structure of a tower head is improved. The specific performance is that original angle steelcross arms are replaced with the FRP composite cross arms, the tower head is improved according to unique insulation characteristics of the composite cross arms, the rigidity deficiency of materials is made up through structure design, and the composite cross arms and the angle steel tower main body are combined reasonably.

Description

technical field [0001] The invention belongs to the field of high-voltage power transmission, and relates to a 110kV cat-head type composite cross-arm tower, in particular to a mid-phase composite cross-arm structure design. Background technique [0002] In transmission lines, the traditional towers used in overhead transmission lines have disadvantages such as high quality, easy corrosion, easy cracking, and short service life. Due to problems such as the structure of the tower body, there are many problems such as wind deflection tripping, guano flashover, wide line corridor, lightning tripping, etc., and the construction cost and operation and maintenance cost are high, and the economic performance is not good. [0003] FRP composite materials have the characteristics of high strength, light weight, corrosion resistance, durability and electrical insulation performance. The material is used to manufacture composite cross-arms of transmission poles and towers, which is be...
