Description
Technical field
It the utility model is related to technical field of electric power, more particularly to cable.
Background technology
Conductor cable is one of most long article used in industry.Tensile strength, bending resistance, the conduction of conductor cable
Ability, weight, it is important indicator.
Conductor cable often stresses one of index Design, and gives up other indexs.
Particularly flexible cable, in the industry with common requirements.The cable of many equipment and equipment connects, and is all desirable
Flexible cable.Such as elevator, driving, movable transformer station, movable electric appliance cabinet, and other split type industrial equipments.
But existing flexible cable, pliability and tensile resistance are mostly insufficient.
Utility model content
The purpose of this utility model is, there is provided graphite fibre strengthens flexible cable, to solve above-mentioned at least one technology
Problem.
The technical problem that the utility model solves can be realized using following technical scheme：
Graphite fibre strengthens flexible cable, including a sheath, and cable core is provided with the sheath, and the cable core includes an insulation
Layer and the core being arranged in insulating barrier, it is characterised in that
The core includes a hollow copper wire；
On the hollow copper wire outer wall alongst, at least three grooves are provided with；
A graphite fibre line is installed with the hollow copper wire.
During based on alternating current through wire, existing Kelvin effect, resistance sizes are substantially determined by the surface area of wire
It is fixed.
In this patent, using hollow copper wire, that is, reduce the usage amount of copper, turn avoid the increase of resistance.It ensure that and lead
Electrical property.
Graphite fibre line also allows have certain conductive capability.Resistance can suitably be reduced.
In above-mentioned design, by setting at least three grooves, the surface area of copper cash is added, and then reduce further electricity
Resistance.
Graphite fibre line, intensity are far longer than copper, and density is far smaller than copper.
Therefore graphite fibre line is penetrated in hollow copper wire, relative to solid copper cash, there is stronger mechanical strength, and
And gravity substantially reduces.
The wall thickness of the hollow copper wire is 0.2mm-2mm, and the depth of the groove is 0.1mm-2mm.
To ensure to have compared with low resistance.
The quantity of the groove is 4-10 bars, is evenly spaced in hollow copper wire outer wall.Resistance is reduced, and uses up hollow copper wire
It is suitable to measure the magnitude of current flowed through everywhere.Avoid hot-spot.
The graphite fibre line external diameter (diameter) is 1mm-3mm.Avoid that graphite fibre line is meticulous, and mechanical strength is inadequate,
Avoid graphite fibre line excessively thick again, lose flexibility.
In production, graphite fibre line is firstly generated, then by the wire drawing together with hot melt copper of graphite fibre line, forms parcel stone
The hollow copper wire of black single.
The core includes at least three hollow copper wires and a steel wire, three hollow copper wires and a steel wire twist and.It is logical
Cross three hollow copper wires and a steel wire twists and increases electric conductivity, and improve tensile strength.
Brief description of the drawings
Fig. 1 is the structural representation of cross section of the present utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Referring to Fig. 1, graphite fibre enhancing flexible cable, including a sheath 1, sheath 1 is interior to be provided with cable core, and it is exhausted that cable core includes one
Edge layer 2 and the core being arranged in insulating barrier 2, core include a hollow copper wire 4.Along length side on the outer wall of hollow copper wire 4
To being provided with least three grooves.A graphite fibre line 5 is installed with hollow copper wire 4.During based on alternating current through wire, exist
Kelvin effect, resistance sizes substantially determined by the surface area of wire.
In this patent, using hollow copper wire 4, that is, reduce the usage amount of copper, turn avoid the increase of resistance.It ensure that and lead
Electrical property.In above-mentioned design, by setting at least three grooves, the surface area of copper cash is added, and then reduce further electricity
Resistance.Graphite fibre line 5, it is that a kind of intensity is slightly below carbon fiber line, cost is but well below the industrial product of carbon fiber line.Intensity
It is far longer than copper, density is far smaller than copper.Therefore graphite fibre line 5 is penetrated in hollow copper wire 4, relative to solid copper cash,
With stronger mechanical strength, and gravity substantially reduces.The wall thickness of hollow copper wire 4 is 0.2mm-2mm, and the depth of groove is
0.1mm-2mm.To ensure to have compared with low resistance.Graphite fibre line also allows have certain conductive capability.Can suitably it reduce
Resistance.
The quantity of groove is 4-10 bars, is evenly spaced in the outer wall of hollow copper wire 4.Resistance is reduced, and hollow copper wire 4 is tried one's best
The magnitude of current flowed through everywhere is suitable.Avoid hot-spot.The external diameter of graphite fibre line 5 (diameter) is 1mm-3mm.Avoid graphite fine
Dimension line 5 is meticulous, and mechanical strength is inadequate, avoids graphite fibre line 5 excessively thick again, loses flexibility.In production, graphite fibre is firstly generated
Line 5, then by the wire drawing together with hot melt copper of graphite fibre line 5, form the hollow copper wire 4 for wrapping up graphite fibre line 5.Core includes
At least three hollow copper wires 4 and a steel wire 3, three hollow copper wires 4 and steel wire 3 twist and.Pass through three Hes of hollow copper wire 4
One steel wire 3 twists and increases electric conductivity, and improve tensile strength.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
