Abstract
The utility model discloses a waterproof cable. The waterproof cable comprises a cable core, filled layers, beltings, an inner sheath and an outer sheath; the cable further comprises a comprehensive waterproof layer structurally; the cable core is formed through twisting a plurality of insulation wires; each insulation wire is formed by a conductor with a compression structure and an insulation layer extruded outside the conductor; gaps among the insulation wires are filled with the filled layers; the outer surfaces of the insulation wires and the filled layers are coated with the beltings; a layer of halogen-free flame-retardant inner sheath is extruded on the outer surfaces of the beltings; the comprehensive waterproof layer is arranged outside the inner sheath; and a layer of outer sheath is extruded on the outer surface of the comprehensive waterproof layer. The utility model designed by adopting the scheme effectively ensures longitudinal water resistance of the conductor and restrains the water tree from generating; meanwhile, the outer sheath of the cable is made of polyolefin material, thereby effectively avoiding penetration of moisture toward the interior of the cable.
Description
Technical field:
The utility model relates to a kind of cable technology, particularly a kind of cable with water-proof function.
Background technology:
Nowadays along with the continuous development of science and technology; very wide of various electric power, transmission of Information network; the purposes of cable is very big also; be applied in places such as harbour, harbour, hydroelectric station, water power, reservoir, tunnel widely; environment complexity very; usually can touch water, even just at underwater work, this is just to the waterproof requirement height very of cable.
The cable that uses generally is made of conductor, insulation, shielding, sheath etc. now, and it is very weak in water resistance, and useful life is short, and in use, needs overhauling of timing, and so not only waste of manpower increases cost, also has very big potential safety hazard simultaneously.
The utility model content:
The utility model is for solving cable when underwater work, and is fragile, the life-span short, the problem of potential safety hazard occurs easily and adopt a kind of simple in structurely, is easy to the water-proof cable of processing and manufacturing.
The utility model can be achieved through the following technical solutions:
Water-proof cable, this cable is made up of cable core, packed layer, band, inner sheath and oversheath; The described construction of cable also comprises one deck comprehensive waterproof layer, described cable core forms by the complex root insulated wire cores is stranded, insulated wire cores is pressed the conductor of structure by employing and is extruded in the outer insulating barrier of conductor and forms, the outer wrapped one deck waterstop of conductor between described conductor and the insulating barrier, fill by packed layer in the space between the described insulated wire cores; On the outer surface of insulated wire cores and packed layer, coat with band; Described one deck halogen-free flameproof inner sheath that extrudes on bag band outer surface, inner sheath is provided with the comprehensive waterproof layer outward, has extruded one deck oversheath on the outer surface of this comprehensive waterproof layer.
The outer wrapped one deck waterstop of described conductor.
Described insulated wire cores has been added material water-proof material when stranded.
The insulating barrier of described insulating barrier for adopting advanced waterproof tree material to make.
Described packed layer, band are for adopting the packed layer and the band of high-quality waterproof material.
The oversheath of described oversheath for adopting the TPO material to make.
The beneficial effects of the utility model by above conceptual design are: 1, the outer waterstop that is provided with of conductor has effectively guaranteed vertically blocking water of conductor; 2, insulating barrier has adopted advanced waterproof tree material, has effectively suppressed the production of water tree, has guaranteed the useful life of insulating barrier; 3, cable jacket adopts the TPO material, has effectively avoided the infiltration of moisture to cable inside.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The utility model is for solving cable when underwater work, and is fragile, the life-span short, the problem of potential safety hazard occurs easily and adopt as shown in Figure 1 the utility model.
The water-proof cable that provides for the utility model with reference to Fig. 1, this cable is made up of cable core, packed layer, band, waterproof synthetic layer, inner sheath, armouring and oversheath, cable core forms by the complex root insulated wire cores is stranded, insulated wire cores is made up of conductor 1 insulating barrier 3 outer with being extruded in conductor, insulating barrier 3 has adopted advanced waterproof tree material, effectively suppress the production of water tree, guaranteed the useful life of insulating barrier 3.The outer also wrapped one deck waterstop 2 of conductor 1 simultaneously, waterstop 2 is arranged between insulating barrier 3 and the conductor 1, and the while insulated wire cores has been added material water-proof material when stranded, effectively guaranteed vertically blocking water of conductor 1.
Coated one deck band 5 outside the filler 4 that insulated wire cores and employing quality material are made, band 5 has also adopted the waterproof material of high-quality to make, and has effectively blocked the passage of moisture diffusion.On band 5 outer surfaces, extrude one deck halogen-free flameproof inner sheath 6, also be provided with one deck comprehensive waterproof layer 7 outside the inner sheath 6 and (once concrete structure, the material of comprehensive waterproof layer please be described, be arranged on which layer), for having set up firm waterproof barrier one in the core of cable.Also extruded simultaneously one deck oversheath 8 on the outer surface of comprehensive waterproof layer 7, this oversheath 8 adopts the TPO material to make, and can effectively avoid moisture to the cable internal penetration.
The utility model has adopted multiple waterproof technology; all be provided with corresponding water-proof protection device in each of cable layer structure; make cable can adapt to various complex environments such as harbour, harbour, hydroelectric station, reservoir, tunnel; not only can contact water and carry out operation, and can be placed directly in the water and move.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
