Description
Technical field
The utility model relates to a kind of wire and cables, and in particular to a kind of abnormally-structured wire and cable.
Background technique
Common aluminum steel shape is respectively round wires and special-shaped wire in current power transmission route.Wherein, round wires are usually used in all kinds of electricity
Cable and steel-cored aluminium strand, production and processing is simple, but gap is larger between round wires, filling rate is small, therefore with the current-carrying capacity under outer diameter
Low, anti-ice cover ability and corrosion resistance are poor；Special-shaped wire shares Z-type, S type, trapezoidal and arch, is usually used in extraordinary conducting wire, same
Layer uses the identical aluminum steel of shape, and gap is small between aluminum steel, conducting wire filling rate is high, and power transmission efficiency is high, but aluminum steel production, processing are more
It is at high cost.
Contact area is maximum between Z-type and S type single line in special-shaped wire, it is close to be engaged, and self-damping performance is best, but produces
Complex procedures when technical process control is more difficult, processing monofilament turns over, breaks, therefore most Special wire are equal both at home and abroad
Using trapezoidal and bow-shaped structural aluminum steel.Trapezoidal and arcuate line in special-shaped wire is only close to compression mould although process control is easier to
It is compacted conducting wire aluminium layer, being also easy to produce interlayer slip between when crimping lead wire each aluminium layer causes to throw stock；In process core wire and internal layer aluminum steel
When having the conducting wire of gap or soft filler, since aluminum steel occurs slightly to slide in process, easily there is " snakelike " surface, influence to lead
Line mass.
Summary of the invention
Purpose of the utility model is to solve above-mentioned technical deficiency, provide a kind of reasonable in design abnormally-structured
Wire and cable, existing " Z " the type aluminum steel same layer aluminum steel of the electric wire cable of the structure is engaged close advantage, also has trapezoidal aluminum steel easy
The advantage of production, processing, and have that special-shaped aluminum steel gap is small, conducting wire filling rate is high, the general advantage of power transmission efficiency height etc..
Technical solution of the present invention: in order to achieve the above object, the present invention takes following technical scheme:
A kind of abnormally-structured wire and cable, it includes: outer contact and internal bearing member, and the outer contact is
2 layers or more, innermost conductor is mutually twisted process and is formed using convex conducting wire and concave conducting wire；
The inside bearing member is steel core or composite core；
Grease is filled between the steel core and outer contact；
The composite core is one of carbon fiber, glass fibre, basalt fibre or aramid fiber or a variety of
With the composite core of resin pultrusion.
Preferably, the abnormally-structured wire and cable of above-described one kind, the outer contact be 2 layers, 2
The thickness of layer conductor is identical or different；2 layers of conductor are all made of convex conducting wire and concave conducting wire is mutually twisted process and forms.
Preferably, the abnormally-structured wire and cable of above-described one kind, the outer layer more than second layer
Conductor is that convex conducting wire and concave conducting wire are mutually twisted process and form or formed using ladder track or round wires process.
Preferably, the abnormally-structured wire and cable of above-described one kind, the composite core are single rod
Or more sticks；Composite core outer layer is by glass fibre or glass fibre establishment net package.
The utility model has the advantages that abnormally-structured wire and cable provided by the utility model has the advantage that
Abnormally-structured wire and cable provided by the utility model, reasonable in design, convex conducting wire and concave conducting wire phase
Mutually occlusion is close, and existing " Z " the type aluminum steel same layer aluminum steel of the electric wire cable of the structure is engaged close advantage, also has trapezoidal aluminum steel easy
Production, easy processing advantage, and have that special-shaped aluminum steel gap is small, conducting wire filling rate is high, self-damping is functional, power transmission efficiency
The advantages that high, is worthy of popularization.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the abnormally-structured wire and cable of one kind provided by the utility model.
Fig. 2 is the cross section structure schematic diagram of the abnormally-structured wire and cable of another kind provided by the utility model.
Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
Embodiment 1
As shown in Figure 1, a kind of abnormally-structured wire and cable, it includes: the bearing member 1 of outer contact 2 and inside, described
Outer contact 2 be 2 layers, 2 layers of conductor are all made of convex conducting wire 3 and concave conducting wire 4 is mutually twisted process and forms；
The bearing member (1) of the inside is steel core；Grease 5 is filled between the steel core and outer contact 2；
Grease 5 is filled between steel core and outer contact, can be prevented steam from entering, be slowed down corrosive wear, can also enhance steel core
Property free to slide.
Embodiment 2
As shown in Fig. 2, a kind of abnormally-structured wire and cable, it includes: the bearing member 1 of outer contact 2 and inside, described
Outer contact 2 be 2 layers, 2 layers of conductor are all made of convex conducting wire 3 and concave conducting wire 4 is mutually twisted process and forms；
The bearing member 1 of the inside is one of carbon fiber, glass fibre, basalt fibre or aramid fiber or more
The composite core of kind and resin pultrusion.
Above-described abnormally-structured wire and cable is mutually twisted using convex conducting wire 3 and concave conducting wire 4, is stranding into and is led
The internal layer of line will not cause longitudinal slight slide of each aluminum steel of internal layer " snakelike " occur in turn because of gap biggish between steel core and aluminium layer
Surface, surface more rounding, wire quality are superior.
When setting up conducting wire, steel core or carbon fiber composite material core and outer contact 2 generate Relative sliding, by steel core or compound
Material cores bear whole pulling force, therefore heat-resistant aluminium alloy material can be used in aluminium layer, has biography compared with traditional steel-cored aluminium strand conducting wire
Defeated twice or more capacity, practicability are stronger.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities
The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention
Monotropic type, these simple variants all belong to the scope of protection of the present invention.
