Description
Technical field
The utility model belongs to technical field of electric wires and cables, is related to a kind of copper with flexible carbon fiber complex core and copper is closed
Golden carrier cable.
Background technology
Twisted wire used by electric railway is mainly copper and copper-alloy stranded conductor and its Related product all the time.This load
Rope twisted wire itself is present from great, and unsuitable large span is maked somebody a mere figurehead；Between environmental corrosion, copper and copper alloy, corrosion is difficult to avoid that；To copper and
The shortcomings of copper alloy demand is big.With the development of electric railway, develop a kind of advanced composite material (ACM) core copper and copper alloy holds
Power rope twisted wire, i.e. carbon fiber rod core copper and copper-alloy stranded conductor.This novel strand compared with conventional twisted wire, with lightweight, anti-
The advantages of tensile strength height, little linear expansion coefficient, saving copper and Cu alloy material, but still suffer from problems with：
One is that existing carbon fiber rod core has that fatigue performance is poor, somewhere defect occurs easily and causes showing for wire fracture
As；Two is that circular copper and copper-alloy stranded conductor are loosely organized, and current-carrying capacity is less.
Utility model content
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided a kind of to have flexible carbon fiber multiple
The copper and copper alloy carrier cable of core is closed, the fatigue resistance of the twisted wire is strong, and current-carrying capacity is larger.
For achieving the above object, the utility model is employed the following technical solutions：
A kind of copper with flexible carbon fiber complex core and copper alloy carrier cable, including the flexibility for setting gradually from inside to outside
Carbon fiber complex core, copper and copper alloy layer and copper and copper-alloy stranded conductor layer；The flexible carbon fiber complex core is by some carbon fibres
Dimension sticklac is closed and is formed；The copper and copper alloy layer are by around the multiple copper and copper alloy wire structures being wrapped on the outside of flexible carbon fiber complex core
It is made up of into, described copper and copper-alloy stranded conductor layer the multiple copper and copper alloy wires on the outside of copper and copper alloy layer is wrapped in.
The flexible carbon fiber complex core is formed by seven carbon fiber rods are stranded.
Seven carbon fiber rods are fine by a carbon fiber rod for being located at center and around the carbon of center
Six roots of sensation carbon fiber rod composition around dimension rod.
The twisting pitch of the flexible carbon fiber complex core is 14-20 times of flexible carbon fiber complex core diameter.
The cross section of the copper and copper alloy wire is that trapezoidal, trapezoidal upper bottom is arranged near flexibility carbon fiber complex core.
The cross section of the copper and copper alloy layer and copper and copper-alloy stranded conductor layer is cirque structure.
The utility model has the advantages that：
Carrier cable of the present utility model includes that flexible carbon fiber complex core, trapezoidal copper and copper alloy layer and copper and copper alloy are twisted
Line layer, wherein flexible carbon fiber complex core are made up of some carbon fiber rods, therefore the endurance of the flexible carbon fiber complex core
Performance is good compared with individual carbon fibers rod, causes the limitation of wire fracture so as to effectively solving single structure optional position defect.
Further, new carrier cable adopts flexible carbon fiber complex core, with section compared with copper and copper alloy carrier cable weight
10%～50% is reduced, tensile strength improves 30%～150%.
Further, the periphery of flexible carbon fiber complex core is provided with trapezoidal copper and copper alloy layer, increases contact area, improves and carries
Flow.
Further, the cross section of the trapezoidal copper and copper alloy layer is cirque structure so that the table of overhead power transmission cable
Face is smooth, effectively increases anti-ice-snow performance, and surface is difficult to adhere to dust, effectively can reduce corona discharge generation noise and
Line loss.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 it is carbon fiber rod, 2 be flexible carbon fiber complex core, 3 be copper and copper alloy layer, 4 is that copper and copper alloy are twisted
Line layer.
Specific embodiment
Below by embodiment and accompanying drawing is combined, the utility model is described in further detail.Embodiment of the present utility model
It is only used for explaining the utility model, is not intended as to restriction of the present utility model.
With reference to Fig. 1, a kind of copper with flexible carbon fiber complex core of the utility model and copper alloy carrier cable, including flexibility
Carbon fiber complex core 2, copper and copper alloy layer 3 and copper and copper-alloy stranded conductor layer 4, flexible carbon fiber complex core 2, copper and copper alloy layer
3 and copper and copper-alloy stranded conductor layer 4 be sequentially distributed from inside to outside.
Flexible carbon fiber complex core 2 is formed by some 1 gluings of carbon fiber rod；The strand of the flexible carbon fiber complex core 2
