Abstract
The utility model discloses a high-temperature-resistant coaxial cable for a downhole tunnel. The high-temperature-resistant coaxial cable comprises a coaxial wire cable core, nickel-plated copper wire braided shielding layer, an insulating layer and a jacket. The coaxial cable core comprises a central conductor, an armor layer and an external conductor. The high-temperature-resistant layer is disposed between the insulating layer and the jacket and comprises a plurality of high-temperature-resistant strips which are tightly arranged in an externally tangential manner. The insulating layer wraps a current guiding line. The jacket is a fluorescent jacket. The cable is good in conductive performance, capable of resisting dragging and preventing breaking, waterproof, capable of resisting dampness, low in smoke, free of halogen, environmental friendly, low in damage to human bodies and surroundings, capable of resisting high temperature, weather-proof, mainly applicable to the downhole tunnel, capable of resisting oil and acid, and capable giving out fluorescent light in dark environments to facilitate cable laying and maintenance.

At present, along with socioeconomic development, cable consumption increases rapidly, and the quality requirement of cable is also constantly improved.Such as in the exploitation work of coal mine, due to underworkings darkness, common cable almost be cannot see or is not seen, and causes the I&M work inconvenience of cable, and safe working is existed to a very large hidden danger.And for example common cable adopts PVC sheath more, and resistance to elevated temperatures is inadequate, once cable fire will discharge a large amount of dense smoke and toxic gas, and impact rescue.Only have many-sided requirement of symbol cable, just can better ensure the safe handling of cable.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide one have conduct electricity very well, shielding is strong, anti-ly pull, waterproof is moisture resistance, high temperature resistant, low smoke and zero halogen environmental protection, simultaneously, can send fluorescence, be convenient to the underworkings high-temperature-resisting coaxial cable of the advantages such as cable installation and maintenance.
The utility model takes following technical scheme to realize: a kind of underworkings high-temperature-resisting coaxial cable, it comprises coaxial core and is wrapped in successively nickel plating copper wire woven shield, insulating barrier, the sheath in coaxial core outside, described coaxial core is made up of center conductor, armour and outer conductor, between described insulating barrier and described sheath, be provided with high-temperature-resistant layer, described high-temperature-resistant layer is closely arranged and is formed by several high temperature resistant bands are mutually circumscribed, drainage thread of described insulating barrier internal package, described sheath is fluorescence sheath.
Described center conductor is to adopt the zinc-plated ultra-fine soft copper tow strand of 99.9999% anaerobic annealing, produce by the 6th kind of special soft copper conductor structure of standard (GB/T3956-2008), described outer conductor is by zinc-coated wire mesh grid, and outer aluminium foil forms, ground connection core of described outer conductor internal package.
Described ground connection core is by zinc-plated annealed copper silk outsourcing annealed wire, overlapping up and down, forms according to the stranded braiding to the right of 20/0.5 (root/square millimeter) ratio.
Described high temperature resistant band is to be composited by ceramic fireproof silicon rubber and the calendering of high temperature resistant alkali-free glass fiber cloth.
Described sheath is to be composited by alkali-free glass fiber cloth and the calendering of ceramic low-smoke halogen-free polyolefin material of adding fluorescer.
The utlity model has in sum following beneficial effect: this kind of cable conduction performance is good, resistance to towing, anti-broken string, waterproof moisture-proof, low smoke and zero halogen environmental protection, damage less to human body and surrounding environment, high temperature resistant weather-proof, wherein, the high-temperature-resistant layer of cable can bear the highest 1000 DEG C, hard housing armouring after burning plays a very good protection to circuit, ensure unimpeded in the situation that of fire of circuit, be mainly used in underworkings, oil resistant is acidproof, anti-oxidant, core is firm, shielding is high, shielding rejection coefficient has reached 96.75%, simultaneously, cable can send fluorescence in dark environment, be conducive to the orientation of identification cable, be convenient to laying and overhaul at shady place of cable.
