Description
Technical field
The present invention relates to field of cables, specially a kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable.
Background technology
Number is, in view of operation safety problem, particularly to lay high ambient temperature, moist and safety to China's power cable greatly absolutely
It is required that the public building occasion such as nuclear power station higher, track traffic and tunnel, building room.In communal facility specific environment, due to
Food is more, and the growth for muroid and termite is highly beneficial, as long as there is the presence of muroid and termite, electric wire, cable will be received
To termite, the biological greatly infringement of muroid.After electric wire and cable jacket material is bitten destruction by mouse, termite, the table of cable
After layer is destroyed, cable is caused to intake or the moisture absorption, it is possible to cause electric leakage or decreasing insulating, not only make to lay place
Surrounding is powered, and the security incident for causing personnel to get an electric shock occurs, and the insulating barrier or screen layer of electric wire are damaged, and can influence electricity
Cable Electric Field Distribution, electromagnetic interference are aggravated, and cause signal transmission chaotic, or even cause the short circuit of cable, cause power failure, communicating interrupt
And the generation of the serious accident such as fire caused by serious short circuit accident.
The content of the invention
It is an object of the invention to provide a kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable, possess cable excellent resistance to
The performances such as high temperature, rat-and-ant proof, waterproof.
In order to realize foregoing invention purpose, the present invention use technical scheme for：A kind of high temperature resistant rat-and-ant proof waterproof copper core electricity
Power cable, including conductor, are coated with crosslinked polyetylene insulated layer and oxygen barrier layer and constitute core successively outside the conductor, it is described at least
Both threads core and packed layer mutually stranded composition cable core, the packed layer is heat-resistant fireproof rope, is coated successively outside the cable core
Have combination waterproof layer and flame-proof polyvinyl chloride sheath, the combination waterproof layer be followed successively by from inside to outside aluminium-plastic tape lapping layer,
Waterstop lapping layer and double-sided aluminum plastic belt lapping layer.
Compared with prior art, technique effect of the invention is：Ensure the insulation electrical performance and mechanical-physical of cable
Can be good, and with the performance such as high fire-retardance, ageing-resistant, waterproof, environmental protection, can effectively prevent mouse to bite and termite moth corrosion energy,
Prevent mouse ant cable is caused to damage；Even if cable jacket by mouse ant or by external force in the case where destroying, when also can be long
Between safely and reliably run.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
The present invention is described in further detail with reference to Fig. 1.
Coated successively outside a kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable, including conductor 1, the conductor 1 crosslinking
Polyethylene layer 2 and oxygen barrier layer 3 constitute core, at least both threads core and the mutually stranded composition cable core of packed layer 4, described
Packed layer 4 is heat-resistant fireproof rope, is coated with combination waterproof layer 5 and flame-proof polyvinyl chloride sheath 6 outside the cable core successively, described
Combination waterproof layer 5 is followed successively by aluminium-plastic tape lapping layer, waterstop lapping layer and double-sided aluminum plastic belt lapping layer from inside to outside.
In such scheme, conductor 1 can be tightly combined using 1 class, 2 class anaerobics annealing steel structure with many conductors, is conducive to
Electric fields uniform.Cable core conductor nominal section is in 2.5mm2-300mm2 Between, core is 1 core to 7 cores.The cable core conductor 1 of cable
Insulating barrier does insulating barrier 2 using crosslinked polyethylene, it is ensured that cable has heat resistance, excellent electrical insulation properties and mechanicalness
Energy, chemical resistance performance.Combination waterproof layer 5 is followed successively by aluminium-plastic tape lapping layer, waterstop lapping layer and two-sided from inside to outside
Aluminum plastic belt lapping layer, so makes cable have the performance such as excellent wear-resisting, waterproof, tear-resistant, cable is born mouse
Ant gnaws, and ensures that cable will not make moist.From the flame-proof polyvinyl chloride sheath 6 of termite-resistant rodent-resistant, further prevent mouse
Bite and termite moth erosion.At least both threads core is high temperature resistant with the mutually stranded composition cable core of packed layer 4, the packed layer 4
Flame-retardant rope, makes cable possess anti-flammability, heat resistance and rotproofness effect.The present invention be adapted to be used in nuclear power station, track traffic and
Under the conditions of the occasions such as tunnel, building room.
The oxygen barrier layer 3 is the dual-layer high-resistance combustion band of the outer cladding of conductor 1, it is ensured that cable integrally possess it is excellent fire-retardant and
Oxygen barrier property, extends the service life of cable.
