Abstract
The utility model discloses a stranded type line diameter-expanded wire comprising an outermost aluminum wire layer, a middle stranded aluminum wire layer, and an innermost steel core. The steel core is formed by multiple steel wires. The stranded aluminum wire layer is formed by twisting multiple circular wires. Aluminum wires on the aluminum wire layer are wrapped round the stranded aluminum wire layer along the radial direction of the circular wires in a circumferential manner. The inner layer of the stranded type line diameter-expanded wire is a twisted aluminum wire beam. The stranded type line diameter-expanded wire has stable supporting structure and good diameter expanding effect and has advantages of large external diameter and a bright and clean surface. The stranded type line diameter-expanded wire has advantages of reducing corona loss, reducing field intensity on line surface, radio interference, and acoustic noise, and having large current-carrying capacity.
Description
Technical field
The utility model relates to a kind of bundle strand shape molded lines expanded conductor.
Background technology
Global electric power transfer all is based on overhead transmission line, and aerial condutor is by the single cord of electric current or the twisted wire formed of the multi cord of mutually insulated not, is the necessary carrier from electric energy generating end to receiving end.China's overhead transmission line is based on steel reinforced aluminium conductor (ACSR), and its applicating history is above 100 years in the world.Traditional steel reinforced aluminium conductor transmission line capability be restricted and line loss bigger, explore new lead line style, efficient electric energy transmitting is various countries electric power scientific worker's continuous pursuit.
Transmission line adopts ultra high voltage, superhigh pressure to become the development trend that electric power is carried at a distance at present.Along with the lifting of electric pressure, aspect electric property, need consider corona characteristic and the resistance characteristic problem of lead.Corona is that electric potential gradient surpasses the free a kind of electric discharge phenomena that cause of lead ambient air after certain critical value.The operation of ultra high voltage, extra high voltage network is easy to generate corona, not only consumes a large amount of energy, and derivative radio interference and audible noise have a strong impact on biological environment.The general external diameter and the smooth finish surface that increase lead of adopting solves in the world.
The utility model content
The utility model purpose is to provide a kind of bundle strand shape molded lines expanded conductor at the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: a kind of bundle strand shape molded lines expanded conductor, comprise outermost aluminium molded lines layer, the bundle strand aluminum steel layer in intermediate layer and the steel core of nexine, described steel core is made of many steel wires, described bundle strand aluminum steel layer is by many stranded the forming of round wire, and the aluminium molded lines on the described aluminium molded lines layer radially is circle-shaped encirclement along described round wire and is arranged in bundle strand aluminum steel layer outside.
Preferably, described aluminium molded lines layer, bundle strand aluminum steel layer and steel core concentric-ring pattern are stranded.
Preferably, described aluminium molded lines layer is 1 layer, and adjacent layer strand is on the contrary, and outermost layer twists to being dextrad.
Preferably, described bundle strand aluminum steel layer also is provided with the clearance layer of one deck, and the adjacent layer strand is on the contrary.
Preferably, the contact-making surface of adjacent described aluminium molded lines is plane or zigzag face.
Preferably, described aluminium molded lines is Z-shaped aluminium molded lines or T type aluminium molded lines.
The beneficial effects of the utility model: the utility model bundle strand shape molded lines expanded conductor internal layer is the aluminum steel bundle of bundle after stranded, and supporting construction is stable, and hole enlargement is effective; Outermost layer aluminium molded lines is Z-shaped or the T type, and lay configuration is tight, the surface smoothness height; Advantages such as the advantage that has possessed big external diameter and smooth finish surface simultaneously has the corona loss of reduction, reduces circuit surface electric field intensity, radio interference and audible noise, and ampacity is big.Guaranteeing to reduce the aluminum conductor cross section under the desired wire diameter situation of corona, thereby reducing the lead total amount, reducing construction weight, reducing tower bar load, reducing advantages such as circuit cost greatly.
