Description
Technical field
The present invention relates to field of cables, more particularly to a kind of Novel cold-resistant high-strength pulling-resisting cable.
Background technique
With the development of power industry, the requirement to cable is higher and higher, for the work for adapting to part low temperature snowy district
Condition, industry propose the requirement such as cold-resistant, high-tensile to cable.Ice and snow falls on overhead cable oneself for increasing cable
Weight, the tensile stress that cable is born increase, will lead to cable when serious and be broken.Common cable is low under the conditions of extremely cold simultaneously
The mechanical property of temperature drop low metal conductor, it is difficult to guarantee that cable works normally under cryogenic, cable be broken a possibility that increase
Add.
Summary of the invention
The technical issues of solution: it is directed to above situation, to overcome prior art defect, the invention aims to provide one
The cold-resistant high-strength pulling-resisting cable of kind is solved the problems, such as in the easy accumulated snow fracture of low temperature snowy district large span aerial cable.
Technical solution: a kind of cold-resistant high-strength pulling-resisting cable, including center core, thermally conductive insulating layer and conductor, it is described thermally conductive
Insulating layer is wrapped in center line wicking surface, and the conductor includes 20 ~ 30 strands of conducting wires, and wire stranding is in heat conductive insulating layer surface,
The grid-shaped annulus of the radial section of the thermally conductive insulating layer.
The center core is single nanometer steel, as carrying and heater.
The heat conductive insulating layer material is natural rubber.
The conductor material is aluminum steel, and aluminum steel has good conductivity, the mechanical property of high-strength light and good leads
It is hot.
It further include the independent current source with remote power control device, the independent current source is set to and cold-resistant high-strength pulling-resisting cable
On the electric pole of connection, and independent current source is electrically connected with center core.
The utility model has the advantages that the present invention resists cold, high-strength pulling-resisting cable is wrapped in the nanometer steel center core of cable innermost layer greatly
The tensile strength for improving cable reduces the risk of aerial cable fracture；And it can will make to receive by changing center line core radius
Meter Gang has reasonable resistivity, and the tailor-made cable is used between the electric pole of frequent accumulated snow circuit section and center core is connected
It is powered on an independent power supply to center core, electric energy is converted into the ice and snow that Thermal energy melts are deposited on cable, according to ring
Border temperature and the snowfall being deposited on cable remotely change the calorific value of power-on voltage control centre core.The heat of generation can delay
Slowly the equably outer ice dissolution that will be deposited on cable of conducting cable, mitigates the weight of cable, reduces the tensile stress of cable, together
When the heat that generates improve the temperature of cable itself, improve the mechanical property of center core and conductor, extend cable service life,
The probability that reduction accident occurs.Meanwhile there is good insulation characterisitic to make for the thermally conductive insulating layer isolation of cold-resistant high-strength pulling-resisting cable
The energization environment for obtaining center core and conductor is not interfere with each other, the grid-shaped circular ring structure of the radial section as made from natural rubber
But also itself having preferably elasticity, cable self weight is reduced, the fracture of rubber insulation is prevented, is independently closed not between grid
It is interconnected, prevents rainwater from penetrating into cable short circuit occurred inside, while the heat generated that also center core can be powered conducts
It goes out.This construction of cable is simple, has good ductility, and tensile strength is high, the suitable more ice and snow areas of low temperature easy to maintain
Overhead transmission line.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention
In figure: 1, center core, 2, thermally conductive insulating layer, 3, conductor.
Specific embodiment
As shown in Figure 1, the present invention is a kind of cold-resistant high-strength pulling-resisting cable, it includes center core 1, and thermally conductive insulating layer 2 is led
Body 3.Innermost layer is the high center core 1 of tensile strength, and center core 1 is fully wrapped around by thermally conductive insulating layer 2, conductor 3 include 20 ~
30 strands of conducting wires, and wire stranding is in 2 surface of thermally conductive insulating layer, the grid-shaped annulus of the radial section of thermally conductive insulating layer 2.
Above-mentioned cable may also include the independent current source with remote power control device, and independent current source is set to and high-strength resist of resisting cold
On the electric pole for drawing cable connection, and independent current source is electrically connected with center core 1.
The center core 1 uses single nanometer steel, bears the case where tensile stress increases in accumulated snow deposition aerial cable
Under greatly improve the tensile strength of cable, reduce the wind that the dangerous situations such as during power Transmission cable fracture occur
Danger, and can will make nanometer steel that there is reasonable resistivity by changing center line core radius.When cable has sleet accumulation, people
It is powered for ground independent current source to center core 1, electric current is transformed into thermal energy, the heat of generation by electric energy when center core 1
The ice dissolution being deposited on cable can be mitigated the weight of cable by amount, reduce the tensile stress in aerial cable.It simultaneously can root
According to environment temperature and the snowfall being deposited on cable, the long-range calorific value for changing power-on voltage control cable and temperature reach long-range
