Abstract
The utility model provides a kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable, including conductor, crosslinked polyetylene insulated layer is coated with outside the conductor successively and oxygen barrier layer forms core, at least two cores and the mutually twisted composition cable core of packed layer, the packed layer is heat-resistant fireproof rope, combination waterproof layer and flame-proof polyvinyl chloride sheath are coated with outside the cable core successively, the combination waterproof layer is followed successively by aluminium-plastic tape lapping layer, waterstop lapping layer and double-sided aluminum plastic belt lapping layer from inside to outside.Ensure that insulation electrical performance and the mechanical and physical performance of cable are good, and with the performance such as high fire-retardance, ageing-resistant, waterproof, environmental protection, can effectively prevent mouse and bite and termite moth corrosion energy, prevent mouse ant and cable is caused to damage；Even if cable jacket in the case where being destroyed by mouse ant or by external force, also can safely and reliably be run for a long time.
Description
Technical field
Field of cables is the utility model is related to, specially a kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable.
Background technology
Number is in view of problem safe for operation to China's power cable greatly absolutely, particularly lays high ambient temperature, humidity and safety
It is required that the public building occasion such as higher nuclear power station, 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 by
To termite, the greatly infringement of muroid biology.After electric wire and cable jacket material is bitten destruction by mouse, termite, the table of cable
After layer is destroyed, cable water inlet or the moisture absorption are caused, it is possible to cause electric leakage or decreasing insulating, not only make laying place
Surrounding is powered, and the security incident for causing personnel to get an electric shock occurs, and the insulating barrier of electric wire or screen layer are damaged, and can influence electricity
Cable Electric Field Distribution, electromagnetic interference aggravate, 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.
Utility model content
The purpose of this utility model is to provide a kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable, possesses cable excellent
High temperature resistant, rat-and-ant proof, the performance such as waterproof.
In order to realize above-mentioned purpose of utility model, the utility model use technical scheme for：A kind of high temperature resistant rat-and-ant proof is prevented
Water Copper core power cable, including conductor, the conductor is coated with crosslinked polyetylene insulated layer successively outside and oxygen barrier layer forms core,
At least both threads core and packed layer are mutually twisted to form cable core, and the packed layer is heat-resistant fireproof rope, outside the cable core
Combination waterproof layer and flame-proof polyvinyl chloride sheath are coated with successively, and the combination waterproof layer is followed successively by aluminium-plastic tape from inside to outside
Lapping layer, waterstop lapping layer and double-sided aluminum plastic belt lapping layer.
Compared with prior art, technique effect of the present utility model is：Ensure the insulation electrical performance of cable and mechanical thing
Rationality can be good, and with the performance such as high fire-retardance, ageing-resistant, waterproof, environmental protection, can effectively prevent mouse and bite and termite moth corrosion
Can, prevent mouse ant and cable is caused to damage；Even if cable jacket in the case where being destroyed by mouse ant or by external force, can also be grown
Time is safely and reliably run.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to Fig. 1.
A kind of high temperature resistant rat-and-ant proof waterproof Copper core power cable, including conductor 1, the conductor 1 coat crosslinking successively outside
Polyethylene layer 2 and oxygen barrier layer 3 form core, at least both threads core and the mutually twisted 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 use 1 class, 2 class anaerobics annealing steel structure, be tightly combined, be advantageous to more conductors
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, ensures 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 make cable that there is 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 loses.At least both threads core and the mutually twisted composition cable core of packed layer 4, the packed layer 4 is high temperature resistant
Flame-retardant rope, cable is set to possess anti-flammability, heat resistance and rotproofness effect.The utility model is adapted to be used in nuclear power station, track friendship
Under the conditions of the occasions such as logical and tunnel, building room.
The oxygen barrier layer 3 fires band for the dual-layer high-resistance of the outer cladding of conductor 1, ensure cable integrally possess it is excellent fire-retardant and
Oxygen barrier property, extend the service life of cable.
