Technical field
The present invention relates to a kind of power cable.
Background technology
Power cable is a kind of cable for being used to transmitting and distributing electric energy, is had extensively in all trades and professions such as communication, civilian
Application, the power cable insulation material sold on open market uses common PVC, external intensity poor performance, when the big electricity of carrying
When stream, high-tension work, external insulation easily deforms, or even punctures, and insulating properties are affected, and works long hours
After may influence power transmission effect, or even occur security incident, particularly cable and be typically all embedded in soil, in road trimming or
The subteranean animal such as destruction easily by mechanical external forces such as excavators or mouse destroys when constructing again.
In the electric industry of conveying, power transmission cable is widely used, and at present, power cable has insulating properties and necessarily anticorrosive
Ability, can be prevented effectively from phase fault and ground fault, be widely used in power distribution network.Existing power cable is general
Using the structure of coated insulation layer outside cored wire, easily occur aging using insulating barrier for a long time, cause the insulating properties of cable to drop
It is low, occur the phenomenons, poor safety performance, the problem of service life of cable is short such as electric leakage, short circuit.
It is well known that cable tunnel, cable duct, cable interlayer, cable shaft etc. are power cable very close quarterses, electricity
Cable, which is overlapped mutually, to press together, because the environment temperature that the current-carrying capacity of power cable is run with cable has a great impact, electricity
Cable can generate heat under the big electric current operating condition of high load capacity, so the when temperature that superposition presses together is often higher, this is not
But the current-carrying capacity of power cable is significantly impacted, while there is also the hidden danger that fire occurs for cable, having had a strong impact on power cable
Safe and stable operation；In addition, the cable for the insulating protective layer that come off to some older corrosions is because its is cross-laminated together, also without
Method carries out power failure rectification.

Experimental example
From the power cable and common power cable of the present invention, it is divided into experimental group and common group, observes two groups of electric power
Cable uses the situation after six months.
Comparing result see the table below：
As can be seen here, power cable intensity of the invention is high, anti-deformation ability is strong and degree of safety is high, with common electric power electricity
Cable is compared, and is obviously improved in performance.
The beneficial effects of the invention are as follows：The power cable designing is simple, simple to operate by being provided with spacer clip, improves
Transmission of electricity security；By being provided with armor, the intensity and anti-deformation ability of cable are improved；By being set in insulating barrier
There is the reinforcement of one or more, further increase the intensity and anti-deformation ability of cable；The setting of flame-retardant layer can prevent cable
Catching fire, improves the security of cable.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, should all cover within the scope of the present invention.
