Abstract
The utility model discloses a composite core cable and aims at improving high tensile strength of cores, greatly reducing the self weight of cables and raising the linear current carrying capacity greatly. The cable comprises a core and an aluminum conductor layer wrapping the outer surface of the core and is characterized in that: the core is constituted by a plurality of strands of basalt fiber bundles (11) and a modified thermoplastic resin layer (12) compositely; each basalt fiber bundle (11) extends along the core longitudinally; the modified thermoplastic resin layer (12) wraps the basalt fiber bundles (11) inside; and the modified thermoplastic resin layer and the basalt fiber bundles are concreted as a whole.
Description
Technical field
The utility model relates to power transmission cable, and particularly a kind of have a high-tensile compounded yarn cable.
Background technology
The overhead power transmission cable is that electric energy is held the carrier that is transported to receiving end from generating, and what generally adopt at present is the wire cored wire cable.This traditional wire cored wire cable by the round steel wire bar of (the Φ 6mm or the Φ 8mm) of certain diameter as heart yearn and many stranded the forming of aluminum steel, there is following deficiency: when cable exceeds the quata to decide design load (about 100 ℃), wire cored wire generates heat and extends, its expansion and contraction＞10～20%, sag of chain is big, and wire cored wire tensile strength is lower, and when serious ice and snow disaster occurring, cable is very easily broken; The reaction that produces electrolysis of wire cored wire energising back and aluminum steel or other parts, the influence use is received the order, and its line loss rate reaches 29%; The wire cored wire weatherability is poor, easily produces oxidation reaction layer, reduction of service life under solar ultraviolet radiation or rainwater etch.
The utility model content
Technical problem to be solved in the utility model provides a kind of compounded yarn cable, and its heart yearn has high-tensile, and the cable deadweight is alleviated significantly, and its line ampacity is greatly enhanced.
The technical scheme that its technical problem that solves the utility model adopts is: compounded yarn cable of the present utility model, comprise heart yearn and the aluminum conductor layer that is wrapped on its outer surface, it is characterized in that: described heart yearn is by some strands of basalt fibre bundles and the modified thermoplastic resin layer is compound constitutes, each basalt fibre bundle is along the heart yearn longitudinal extension, and the modified thermoplastic resin layer is wrapped in the basalt fibre bundle in it and fixedly is one.
The beneficial effects of the utility model are, have increased substantially the tensile strength of heart yearn, tensile strength 〉=2100MPa, and percentage elongation≤3.0% effectively solves the cable sagging problem; Compare with the steel reinforced aluminium conductor cable of same diameter, double current-carrying capacity can be provided, weight is 1/4 of steel core; Can under higher temperature, work temperature tolerance 〉=220 ℃; Heart yearn is anticorrosive, and does not have etching problem between bimetallic; Can effectively reduce the quantity of cable rack, or reduce the height of cable rack.
Description of drawings
This specification comprises as next width of cloth accompanying drawing:
Fig. 1 is the cross-section structure schematic diagram of the utility model compounded yarn cable.
Parts shown in the figure, toponym and pairing mark: basalt fibre bundle 11, modified thermoplastic resin layer 12, unlined aluminium lead 21, outer aluminum conductor 22.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, compounded yarn cable of the present utility model, comprise heart yearn and the aluminum conductor layer that is wrapped on its outer surface, described heart yearn constitutes by some strands of basalt fibre bundles 11 and modified thermoplastic resin layer 12 are compound, each basalt fibre bundle 11 is along the heart yearn longitudinal extension, and modified thermoplastic resin layer 12 is wrapped in basalt fibre bundle 11 in it and fixedly is one.The utility model solves the cable sagging problem effectively by having increased substantially heart yearn tensile strength, compares with the steel reinforced aluminium conductor cable of same diameter, and double current-carrying capacity can be provided.Compounded yarn can be worked under higher temperature, reaches as high as 400 degrees centigrade, and has good corrosion resistance, can not produce etching problem between bimetallic.Can effectively reduce the quantity of cable rack, or reduce the height of cable rack, thereby reduce the cost of power transmission engineering.
With reference to Fig. 1, the quantity on described basalt fibre bundle 11 edges is generally 3～6 strands, and each basalt fibre bundle 11 is twisted together into rope form.With the basalt fibre of diameter 6.8 μ m/1200tex, the basalt fibre bundle 11 that the process creel is combined into even tension, its line density should be 43000tex during production.Basalt fibre bundle 11 is through 48 special-purpose ingot disk braiding machines of modified thermoplastic resin dipping back quilt, lateral cross braiding uniformly is made into rope form with it, after unnecessary resin is removed in the process extruding, regulate sliver tension force once more and will send into the mould pultrusion and become composite bar, detect through oven dry at last, batch the basalt fibre compounded yarn.
With reference to Fig. 1, described aluminum conductor layer is made of unlined aluminium lead 21, the outer aluminum conductor 22 with the heart yearn concentric arrangement, and wherein unlined aluminium lead 21 is stranded on the outer surface of heart yearn, and 22 of outer aluminum conductors are stranded on the outer surface of unlined aluminium lead 21.For make between each aluminum steel, between the outer surface of internal layer aluminum steel 21 and compounded yarn, can fit tightly between internal layer aluminum steel 21 and the outer aluminum steel 22, the section of described internal layer aluminum steel 21, outer aluminum steel 22 is fan-like pattern.
Some principles of the above the utility model compounded yarn cable that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
