Abstract
The invention discloses a waterproof fluorescent cable for an underground roadway. The waterproof fluorescent cable for the underground roadway comprises main cable cores, a nylon non-woven fabric taped covering layer, a silicone rubber insulation layer, a nickel plated copper braid shielding layer and a fluorescent sheath, wherein the main cable cores are wrapped in the nylon non-woven fabric taped covering layer, the silicone rubber insulation layer, the nickel plated copper braid shielding layer and the fluorescent sheath sequentially, the three sets of main cable cores are evenly wrapped in the nylon non-woven fabric taped covering layer in an extruding mode, a grounding wire core is arranged in the silicone rubber insulation layer, a waterproof layer is arranged between the nickel plated copper braid shielding layer and the fluorescence sheath, and the waterproof layer is composed of a waterproof outer layer, a waterproof inner layer and a water absorbing layer. The cable is good in conductive performance, resistant to dragging, winding, breakage, weather and high temperature, the cable is mainly applied to underground roadways, the cable is waterproof, resistant to moisture and high in shielding performance, meanwhile, the cable can give out fluorescent light, the position of the cable can be recognized easily, and the cable can be laid and maintained easily in a dark place.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of underworkings waterproof fluorescence cable.
Background technology
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, because operational environment is moist for a long time, traditional cable cannot meet the waterproof requirement of real work.As long as meet the requirements, just can meet the actual service condition 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 one and there is fire-retardant, high temperature resistant, waterproof oil resistant, anti-interference and can send fluorescence, utilize lay, the underworkings waterproof fluorescence cable of the advantages such as maintenance.
The present invention takes following technical scheme to realize: waterproof fluorescence cable for a kind of underworkings, it comprises master core and is wrapped in successively the nylon nonwoven fabrics lapping layer in master core outside, silicone rubber insulation layer, nickel plating copper wire woven shield, fluorescence sheath, described master core is three groups, evenly be extruded in described nylon nonwoven fabrics lapping layer inside, a ground connection core is also wrapped up in described silicone rubber insulation layer inside, between described nickel plating copper wire woven shield and described fluorescence sheath, be provided with watertight composition, described watertight composition is by waterproof outer layer, three layers of composition of waterproof internal layer and water accepting layer.
Described master core is made up of copper conductor and the fluorubber insulating barrier, the aluminium foil braid that are wrapped in outside copper conductor, described copper conductor is to adopt the zinc-plated ultra-fine soft copper tow strand of 99.9999% anaerobic annealing, produces by the 6th kind of special soft copper conductor structure of standard (GB/T3956-2008).
Described fluorescence sheath is to be composited by alkali-free glass fiber cloth and the calendering of ceramic pvc material of adding fluorescer.
Described ground connection core is to be formed by the upper and lower overlapping stranded braiding to the right of annealed copper aluminum-alloy wire of electroplate, and described earth connection core diameter is 0.75 millimeter.
The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, resistance to towing, resistance to coiling, anti-broken string, weather-proof high temperature resistant, be mainly used in underworkings, waterproof is moisture resistance, shielding is high, anti-vibration, meanwhile, fluorescence sheath 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.
