Abstract

The invention discloses a dragging-prevention fluorescent cable comprising main wire cores, a semi-conductive wrapping-winding layer, a nickel-plated aluminum wire braid armored layer and a fluorescent sheath. A grounding wire core is arranged in the center inside the semi-conductive wrapping-winding layer. The three main wire cores are arranged and respectively tangent to the grounding wire core. A reinforcement part is arranged between every two main wire cores, and the space between the nickel-plated aluminum wire braid armored layer and the fluorescent sheath is wrapped by a metal layer. The cable is good in electric conduction, resistant to static, dragging, oil, acid and moisture and waterproof, is mainly applied to the fields of power generation, metallurgy, chemical engineering, petroleum and others and particularly suitable for underworkings, resistant to oxidation, firm in wire core, low in smoke, free of halogen, convenient to install and maintain and environmentally friendly and can emit fluorescent light.

Description

A kind of anti-fluorescence cable that pulls

Technical field

The present invention relates to field of cables, relate in particular to a kind of anti-fluorescence cable that pulls.

Background technology

At present, along with the increase of cable consumption, also more and more higher to the quality requirement of cable.The cable using in the fields such as computer, communication, generating, chemical petroleum, to the insulation property of cable, anti-interference, fire-retardant, high temperature resistant, resistance to oxidation, the aspect quality requirements such as waterproof oil resistant are all very high.But existing cable also exists deficiency, such as in night or the situation such as operational environment light is dark, common cable almost be cannot see or is 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, resistance to elevated temperatures deficiency, once and burning will discharge a large amount of dense smoke and toxic gas, strengthen rescue difficulty.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 possess fire-retardantly, high temperature resistant, anti-pulling, insulate anti-interference, and waterproof oil resistant can send fluorescence simultaneously, is convenient to the anti-fluorescence cable that pulls of the advantages such as installation and repairing.

The present invention takes following technical scheme to realize: a kind of anti-fluorescence cable that pulls, the semiconductive that it comprises master core and is wrapped in successively master core outside holds layer, nickel plating aluminium wire braiding armour, fluorescence sheath, described semiconductive holds a layer inside center and is provided with ground connection core, described master core is three groups, circumscribed with described ground connection core respectively, described master core is provided with reinforcement between any two, coated metal layer between described nickel plating aluminium wire braiding armour and described fluorescence sheath.

Described master core is made up of the conductor wire core of multiply nickel plating aluminium wire outsourcing annealed wire, stack stranded braiding to the right up and down and the tinned copper wire woven shield, the fluoroplastic insulation layer that are wrapped in conductor wire core outside, and heater wire is also wrapped up in described fluoroplastic insulation layer inside.

Described heater wire is to be formed by the zinc-plated ultra-fine copper wire outsourcing aluminium foil braiding of anaerobic annealing.

Described metal level is to be made up of high density annealed wire armouring polytetrafluoroethylmaterial material.

Described fluorescence sheath is to be made up of interpolation antioxidant, waterproofing unction, organosilyl low smoke and zero halogen fluorescence polyolefin fire proofing.

The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, and antistatic is high temperature resistant, anti-pulling, oil resistant is acidproof, waterproof moisture-proof, be mainly used in the fields such as generating, metallurgy, chemical petroleum, be particularly useful for underworkings, anti-oxidant, core is firm, and low smoke and zero halogen environmental protection damages less to human body and surrounding environment, simultaneously, cable can send fluorescence, is convenient to accurately locate in dark surrounds, is convenient to installation and the maintenance etc. of cable.

Embodiment

As shown in Figure 1, a kind of anti-fluorescence cable that pulls, the semiconductive that it comprises master core 1 and is wrapped in successively master core 1 outside holds layer 3, nickel plating aluminium wire braiding armour 4, fluorescence sheath 8, described semiconductive holds layer 3 inside center and is provided with ground connection core 6, described master core 1 is three groups, circumscribed with described ground connection core 6 respectively, described master core 1 is provided with reinforcement 2 between any two, coated metal layer 5 between described nickel plating aluminium wire braiding armour 4 and described fluorescence sheath 8.

Described master core 1 is made up of the conductor wire core of multiply nickel plating aluminium wire outsourcing annealed wire, stack stranded braiding to the right up and down and the tinned copper wire woven shield, the fluoroplastic insulation layer that are wrapped in conductor wire core outside, and heater wire 7 is also wrapped up in described fluoroplastic insulation layer inside.

Described heater wire 7 is to be formed by the zinc-plated ultra-fine copper wire outsourcing aluminium foil braiding of anaerobic annealing.

Described metal level 5 is to be made up of high density annealed wire armouring polytetrafluoroethylmaterial material, can effectively prevent that cable is pulling mechanical damage causing in process etc.

Described fluorescence sheath 8 is to be made up of interpolation antioxidant, waterproofing unction, organosilyl low smoke and zero halogen fluorescence polyolefin fire proofing, and cable can send fluorescence, is convenient to accurately locate in dark surrounds, is convenient to installation and the maintenance etc. of cable.

The permission bending radius of this cable is the outside diameter of cable 15 times; Allowing cable maximum operating temperature is 150 DEG C; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.

The above is the embodiment of the present 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.
