Description
Technical field
The utility model belongs to lead technology field used for transmission line, is specifically related to a kind of dredging around expanding compound reinforced core aluminium stranded conductor.
Background technology
Wire used for transmission line usually adopts steel reinforced aluminium conductor, steel core aluminum alloy stranded wire or adopts aluminum-cladding stranded wire, and its structure is aluminum steel, aluminium alloy wire or aluminium-clad steel wire at outer stranded one deck of steel stranded core or more.If this wire is in ultra-high-tension power transmission line or high altitude localities circuit, because the electric field strength on its surface is high, withstands corona poor performance, easily make outer layer line produce to burn, corona discharge is also with high-frequency noise, radio interference simultaneously, so adopt expanded conductor can alleviate this phenomenon to a great extent.
Chinese patent Authorization Notice No. CN2672807Y recommends to be had " dredging around protecting footpath steel reinforced aluminium conductor ", it is at the outer closing lay aluminum-wire layer of steel stranded core, and arrange between steel core and aluminum-wire layer and dredge around expanding aluminum-wire layer, this patent formula can expand the external diameter of wire, reduce the electric field strength of conductive line surfaces, avoid corona to amplify, reduce wireless interference.But there is following shortcoming: one is owing to have employed steel stranded core, thus make wire heavy, increase erection difficulty; Two be due to be positioned at steel stranded core (custom claim heart yearn) and dredge easy production electrochemical corrosion between expanding aluminum-wire layer and magnetic loss seriously, thus easily affect wire intensity and useful life." filling expanding steel-cored aluminium twisted wire " that Authorization Notice No. CN201383358Y provides is for CN2672807Y, in expanding aluminum-wire layer, polyethylene packing has been set up thin, this patent formula has positive effect for improving steel stranded core and dredging structural stability between expanding aluminum-wire layer, but is still not enough to the described shortcoming making up CN2672807Y.
For above-mentioned prior art, be necessary rational modification in addition, the applicant has done useful design for this reason, and defines technical scheme described below.
Summary of the invention
Task of the present utility model is to provide a kind of and contributes to remarkable weight reduction and use convenient construction unwrapping wire, be conducive to significantly improving intensity and use and increase the service life, be of value to and avoid at heart yearn and dredge and between expanding aluminum-wire layer, produce electrochemical corrosion and use and reduces the thin around expanding compound reinforced core aluminium stranded conductor of magnetic loss.
Task of the present utility model has been come like this, a kind of thin around expanding compound reinforced core aluminium stranded conductor, comprise heart yearn, outer closing lay aluminum-wire layer and dredging around expanding aluminum-wire layer between heart yearn and outer closing lay aluminum-wire layer, be characterised in that: described heart yearn is carbon fiber complex core or basalt fibre composite core.
In a specific embodiment of the present utility model, described carbon fiber complex core or basalt fibre composite core are the carbon fiber complex core of simple solid or the basalt fibre composite core of simple solid.
In another specific embodiment of the present utility model, described dredge around the number of plies of protecting footpath aluminum-wire layer be one deck or more.
In another specific embodiment of the present utility model, the number of plies of described outer closing lay aluminum-wire layer is one deck or more.
In another specific embodiment of the present utility model, when the number of plies of described outer closing lay aluminum-wire layer is two-layer or more, the difference of the aluminum steel radical between the outer and adjacent two layers of internal layer is the six roots of sensation.
The technical scheme that the utility model provides due to using carbon fiber complex core or basalt fibre composite core as the heart yearn playing supporting and gain in strength, thus can significantly weight reduction, be extremely conducive to the construction line-putting; Because carbon fiber complex core or basalt fibre composite core have excellent intensity, the useful life of wire thus can be ensured; Due to by dredging the external diameter expanding wire around expanding aluminum-wire layer, thus greatly can reduce the electric field strength of conductive line surfaces, avoiding corona discharge and reducing wireless interference; Owing to have employed carbon fiber complex core or basalt fibre composite core, thus can avoid heart yearn and dredge electrochemical corrosion between expanding aluminum-wire layer and reduce magnetic loss; Total quality due to heart yearn is light and tensile strength is excellent and vibrationproof performance is good, thus can reduce the height of electric pole or steel tower, increases circuit archives distance and use conservation of power and implement resource.
