Description
Technical field
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, are important indicators.
Conductor cable is often to stress one of index Design, and gives up other indexs.
Utility model content
The purpose of this utility model is to strengthen cable there is provided low resistance lightweight, asked with solving at least one above-mentioned technology
Topic.
The technical problem that the utility model is solved can be realized using following technical scheme：
Low resistance lightweight, which strengthens, is provided with cable core in cable, including a sheath, the sheath, the cable core includes an insulating barrier
And it is arranged on the core 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 basalt fibre line is installed with the hollow copper wire.
During based on alternating current through wire, the Kelvin effect existed, resistance sizes are substantially determined by the surface area of wire
It is fixed.
In this patent, using hollow copper wire, that is, the usage amount of copper is reduced, 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.
Basalt fibre line, is a kind of intensity slightly below carbon fiber line, cost is but well below the industry system of carbon fiber line
Product.Intensity is far longer than copper, and density is far smaller than copper.
Therefore basalt fibre line is penetrated in hollow copper wire, relative to solid copper cash, with stronger mechanical strength,
And gravity is substantially reduced.
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
Measure the magnitude of current flowed through everywhere suitable.Avoid hot-spot.
The basalt fibre line external diameter (diameter) is 1mm-3mm.Avoid basalt fibre line meticulous, mechanical strength is not
It is enough, avoid basalt fibre line excessively thick again, lose flexibility.
In production, basalt fibre line is firstly generated, then by the wire drawing together with hot melt copper of basalt fibre line, bag is formed
Wrap up in the hollow copper wire of basalt fibre line.
The core includes at least three hollow copper wires and a steel wire, three hollow copper wires and 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, low resistance lightweight enhancing cable, including a sheath 1, sheath 1 is interior to be provided with cable core, and cable core includes an insulation
Layer 2 and the core being arranged in insulating barrier 2, core include a hollow copper wire 4.On the outer wall of hollow copper wire 4 alongst,
It is provided with least three grooves.A basalt fibre line 5 is installed with hollow copper wire 4.During based on alternating current through wire, exist
Kelvin effect, resistance sizes are substantially determined by the surface area of wire.
In this patent, using hollow copper wire 4, that is, the usage amount of copper is reduced, 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.Basalt fibre line 5, is a kind of intensity slightly below carbon fiber line, cost is but well below the industrial product of carbon fiber line.By force
Degree is far longer than copper, and density is far smaller than copper.Therefore basalt fibre line 5 is penetrated in hollow copper wire 4, relative to solid copper
Line, with stronger mechanical strength, and gravity is substantially reduced.The wall thickness of hollow copper wire 4 is 0.2mm-2mm, the depth of groove
For 0.1mm-2mm.To ensure to have compared with low 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 basalt fibre line 5 (diameter) is 1mm-3mm.Avoid the Black Warrior
Rock single 5 is meticulous, and mechanical strength not enough, avoids basalt fibre line 5 excessively thick, lose flexibility again.In production, firstly generate profound
Military rock single 5, then by the wire drawing together with hot melt copper of basalt fibre line 5, forms the hollow copper of parcel basalt fibre line 5
Line 4.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
Bar hollow copper wire 4 and a steel wire 3 twist and increase electric conductivity, and improve tensile strength.
General principle of the present utility model and principal character and advantage of the present 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 utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
