Abstract
The invention discloses a cable with good loss-prevention water-proof performance. The cable comprises a cable core. The cable core comprises at least two line cores, each line core is formed by a conductor and an insulation layer wrapped outside a conductor outer layer. The cable core comprises fillers among the line cores. A water-proof taped covering is arranged outside the cable core, a comprehensive water-proof layer is wrapped outside the water-proof taped covering, an armor layer made of a composite metal material is wrapped outside the comprehensive water-proof layer, and an outer sheath is wrapped outside the armor layer. The cable has the advantages that during installing and use, the armor layer can resist damage caused by hard object touching such as mechanical abrasion and biting of rats, the cable is wrapped by multiple layers of water-proof materials, damping probability of the cable line cores is greatly reduced, electric insulation performance of the cable is guaranteed, and the cable can work normally and stably in a damping changeable environment.
Description
Technical field
The present invention relates to a kind of cable.
Background technology
Nowadays along with the fast development of electric power and the communications industry, the use occasion of cable is more and more extensive, and settles the also complicated variation of place of cable.The environment moist, numerous and diverse such as harbour, harbour, hydroelectric station, reservoir, tunnel etc., cable also should have the function of good anti-mechanical damage except possessing the fire resistance characteristic in these cases.But existing cable often can not possess the functional characteristic of anti-mechanical damage and waterproof simultaneously when installing and using, cable laying is in above-mentioned place, because cable cover(ing) lacks good permeability resistance and mechanical bruise resistance, water is easy to penetrate into cable inside, insulating barrier to the parcel cable causes Latent destruction, thereby have influence on the useful life of cable, can directly cause the cable cisco unity malfunction when more serious.
Summary of the invention
The technical problem that the present invention solves is: a kind of cable that possesses good loss prevention water resistance is provided, guarantees normal stable use in moist, numerous and diverse laying environment.
Technical scheme provided by the invention is: a kind of cable, comprise cable core, comprise cable core, cable core comprises at least two cores, and core is by conductor and be wrapped in the outer field insulating barrier of conductor and consist of, and cable core also comprises the filler that is filled between each root core, the cable core outer wrapping lapping layer that blocks water, the lapping layer outer wrapping that blocks water Comprehensive Preventing water layer, the armour that a kind of composite material of Comprehensive Preventing water layer outer wrapping is made, armour outer wrapping oversheath.
Described filler is made of the many gasket for packings that block water, and the gasket for packing that blocks water is a kind of rope shape materials that is composited by polyester fiber, adhesive and rapid expanding water-absorbing resin.
The described lapping layer that blocks water is by wrapped the forming of a kind of nonwoven fabrics waterstop, and described a kind of nonwoven fabrics waterstop is composited by polyester non-woven fabric, adhesive and rapid expanding water-absorbing resin.
Described Comprehensive Preventing water layer comprises aluminum plastic composite belt longitudinal covering and polyolefin jacket layer.
The armour that described composite material is made is zinc-plated steel band.
Described oversheath is by a kind of or several compound the making in the thermoplasticss such as PC, PVC, PP, PE.
The beneficial effect that the present invention brings is: adopt armour in the technique scheme to make cable can stop well that the protection cable is installed and used in the process because mechanical wear and mouse such as bait at the hard thing and touch the damage that brings; The Comprehensive Preventing water layer can be blocked in the cable outside fully with water, and has the characteristic of anti-electromagnetic interference and anti-mechanical stretching; Even the Comprehensive Preventing water layer sustains damage, to the cable inner penetration, meet water and expand rapidly, stops water further to permeate the harm core by block water lapping layer and filler through the lapping layer that blocks water for outside water.The multilayer waterproof material that blocks water coats cable, and the probability that cable core is made moist reduces greatly, has guaranteed the electrical insulation properties of cable, makes the cable can normal stable work in the changeable environment of humidity.
Description of drawings
Fig. 1 is the sectional view of embodiments of the invention;
Among the figure: 1, conductor, 2, insulating barrier, 3, filler, 4, the lapping layer that blocks water, 51, the aluminum plastic composite belt longitudinal covering, 52, the polyolefin sheath, 6, armour, 7, oversheath.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
A kind of cable comprises cable core, and cable core comprises at least two cores, and present embodiment is explained as an example of the cable core that comprises 3 cores example.As shown in Figure 1, core is by conductor 1 and be wrapped in conductor 1 outer field insulating barrier 2 and consist of, and cable core also comprises the filler 3 that is filled between each root core, and filler 3 is made of the many gasket for packings that block water.The gasket for packing that blocks water is a kind of rope shape materials that is composited by polyester fiber, adhesive and rapid expanding water-absorbing resin, meets water and expands rapidly, can stop the further infiltration of water, and its diameter is 2.5～15mm.
The cable core outer wrapping lapping layer 4 that blocks water, the lapping layer 4 that blocks water is by wrapped the forming of a kind of nonwoven fabrics waterstop, and its thickness is 0.15～0.5mm.Described nonwoven fabrics waterstop is composited by polyester non-woven fabric, adhesive and rapid expanding water-absorbing resin, has similar water resistance characteristic to the above-mentioned gasket for packing that blocks water.
The lapping layer 4 outer wrapping Comprehensive Preventing water layers that block water, the Comprehensive Preventing water layer comprises aluminum plastic composite belt longitudinal covering 51 and polyolefin jacket layer 52.Because aluminium plastic composite material and polyolefine material can both waterproof, corrosion-resistant, also have good toughness and insulating properties, so the Comprehensive Preventing water layer is except can with the water resistance gear externally, also having the performance of good anti-electromagnetic interference and anti-mechanical stretching.
The armour 6 that a kind of composite material of Comprehensive Preventing water layer outer wrapping is made, described composite material is zinc-plated steel band, mainly prevents the destruction that cable brings because of the touching that is subject to hard thing and wearing and tearing in installation process.Armour 6 outer wrapping oversheaths 7, oversheath 7 has good physically encapsulation by a kind of or several compound the making in the thermoplasticss such as PC, PVC, PP, PE.
