Abstract
The invention discloses a waterproof and double-shielded coaxial cable. The waterproof and double-shielded coaxial cable comprises a coaxial wire core, a nickel-plated aluminum wire braided shielding layer, an insulating layer and a sheath, wherein the nickel-plated aluminum wire braided shielding layer, the insulating layer and the sheath sequentially wrap the coaxial wire core. The coaxial wire core is composed of an inner conductor, a tinned copper wire braided shielding layer and an outer conductor. A waterproof layer is arranged between the EPR insulating layer and the sheath in a wrapping mode and formed by distributing a plurality of waterproof belts closely in an externally-tangent mode. The sheath is a fluorescent sheath. The cable is good in conductivity, resistant to high temperature, resistant to water and moisture, low in smoke, free of halogen, friendly to environment, small in damage to the human body and the ambient environment, high in shielding performance, resistant to dragging, especially suitable for underground roadways, resistant to oil and acid and resistant to oxidation, and the wire core is firm. Meanwhile, the cable can emit fluorescent light, so that installation and maintenance in darkness are convenient.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of waterproof double shielded coaxial cable.
Background technology
At present, existing cable also exists deficiency, and such as in night or the situation such as operational environment light is dark, common cable almost be cannot see or do not seen, and causes the maintenance of cable and the inconvenience of installation.And for example existing cable is generally that surface cover has PVC sheath outside cable, and resistance to elevated temperatures is not enough, once and burning will discharge a large amount of dense smoke and toxic gas, strengthen rescue difficulty.Yet in fields such as computer, communication, electric power, metallurgy, chemical petroleums, very high to the quality requirement of cable.Not only require cable to possess to conduct electricity very well, anti-ly pull, core is firm, many-sided advantage such as high temperature resistant, anti-oxidant, anti-interference, and, once cable fire can not discharge a large amount of dense smoke and toxic gas as prior cable, impact rescue.Only have many-sided requirement of symbol cable, just can better guarantee the safe handling of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of have conduct electricity very well, shielding is strong, anti-ly pull, waterproof is anti-oxidant, high temperature resistant, low smoke and zero halogen environmental protection, can send fluorescence, be convenient to the waterproof double shielded coaxial cable of the advantages such as cable installation and maintenance simultaneously.
The present invention takes following technical scheme to realize: a kind of waterproof double shielded coaxial cable, nickel plating aluminium wire woven shield, insulating barrier, sheath that it comprises coaxial core and is wrapped in successively coaxial core outside, described coaxial core is comprised of inner wire, tinned copper wire woven shield and outer conductor, between described insulating barrier and described sheath, wrap up watertight composition, described watertight composition is closely arranged and is formed by several water blocking tapes are mutually circumscribed, and described sheath is fluorescence sheath.
Described inner wire is the outer stranded cable core of coppered wire of zinc-plated aluminium wire, and described outer conductor is by zinc-coated wire mesh grid, and outer aluminium foil forms.
Described water blocking tape is that the crosslinked macromolecule water uptake cotton material that adds coal particle, waterproofing unction of the non-hydroscopicity polyvinyl chloride of modification forms.
Described insulating barrier is to consist of high density annealed wire armouring polytetrafluoroethylmaterial material.
Described fluorescence sheath is to consist of the low-smoke halogen-free polyolefin material that adds fluorescer, anti-ointment, expanded perlite.
The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, high temperature resistant, waterproof moisture-proof, low smoke and zero halogen environmental protection, less to human body and surrounding environment damage, anti-pulling, is mainly used in the fields such as computer, communication, electric power, metallurgy, chemical petroleum, be particularly useful for underworkings, oil resistant is acidproof, anti-oxidant, and core is firm, shielding is high, shielding rejection coefficient has reached 97.45%, and meanwhile, cable can send fluorescence, be convenient in dark surrounds accurately location, be convenient to the installation of cable and maintenance etc.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, inner wire; 2, tinned copper wire woven shield; 3, outer conductor; 4, nickel plating aluminium wire woven shield; 5, insulating barrier; 6, watertight composition; 7, sheath.
Embodiment
As shown in Figure 1, the present invention takes following technical scheme to realize: a kind of waterproof double shielded coaxial cable, nickel plating aluminium wire woven shield 4, insulating barrier 5, sheath 7 that it comprises coaxial core and is wrapped in successively coaxial core outside, described coaxial core is comprised of inner wire 1, tinned copper wire woven shield 2 and outer conductor 3, between described insulating barrier 5 and described sheath 7, wrap up watertight composition 6, described watertight composition 6 is closely arranged and is formed by several water blocking tapes are mutually circumscribed, and described sheath is fluorescence sheath.
Described inner wire 1 is the outer stranded cable core of coppered wire of zinc-plated aluminium wire, and described outer conductor 3 is by zinc-coated wire mesh grid, and outer aluminium foil forms.
Described water blocking tape is that the crosslinked macromolecule water uptake cotton material that adds coal particle, waterproofing unction of the non-hydroscopicity polyvinyl chloride of modification forms, and has higher water resistance.
Described insulating barrier 5 is to consist of high density annealed wire armouring polytetrafluoroethylmaterial material.
Described fluorescence sheath is to consist of the low-smoke halogen-free polyolefin material that adds fluorescer, anti-ointment, expanded perlite, cable can send fluorescence in night or the dark environment of light, be convenient in dark surrounds accurately location, be convenient to the installation of cable and maintenance etc.
Permission bending radius of the present invention is the outside diameter of cable 10 times; This cable permission work maximum temperature is 150 ℃; The shielding rejection coefficient of this cable has reached 97.45%.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
