Abstract
The utility model relates to a special chemical electric cable, which comprises a cable core, an inner sheath and an outer sheath. The special chemical electric cable is characterized in that the cable core is formed through stranding a plurality of insulation wire cores of bearing loads and surrounding bearing loads, wherein the insulation wire cores comprise insulation conductors coated with polyfluortetraethylene on the outer wall; the bearing loads adopt steel strand structure; and sheathing layers are extruded outside the bearing loads. The special chemical electric cable has the advantages of reasonable and simple structure, low cost, high tensile strength, good anti-corrosion effect, strong capability of environment adaptability, reliable operation, favorable shielding property and safety and usability of the electric cable at the same time, and can be extensively applied to installation of transmission lines in special environments in the major engineering construction of petrochemical industry, medicine, iron steel, and the like.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of chemical industry special cable.
Background technology
At present chemical industry adopts copper conductor, screen with cable more, and cost height, cable tensile strength are poor, corrosion-resistant, and especially cable in use any problem can not occur, and the single construction of cable can't meet the demands.
Summary of the invention
The purpose of this utility model be exactly for solve present chemical industry with cable expensive and problems such as tensile strength is poor, anticorrosion, provide a kind of and have simple in structurely, easy to use, can effectively reduce cable cost and tensile strength, anticorrosion cable.
For achieving the above object, the utility model adopts following technical scheme:
A kind of chemical industry special cable, this cable comprise cable core, interior oversheath, it is characterized in that forming cable core by the carrying lotus with around many eradications edge core stranding of carrying lotus; Wherein, insulated wire cores is made of the conductor that outer wall coats teflon insulation, and the carrying lotus adopts strand structure to make, and the carrying lotus extrudes restrictive coating outward.
Above-mentioned cable core places in the obturator, the outer wrapped lapping layer of obturator; Lapping layer extrudes in inner sheath after coating the aluminum plastic composite belt longitudinal covering outward; Wrapped armour in the middle of inner sheath and the oversheath.Aluminum plastic composite belt longitudinal holds outside the covering, is the thermoplastic welding, and no seam can strengthen shielding and water-proof function.
The polytetrafluoroethylene restrictive coating that the interior oversheath of the polyamides material that the utility model uses and carrying lotus extrude outward, the protective action of existing sheath has in the past strengthened the Corrosion Protection of cable again, makes the environment for use of cable more extensive.
Above-mentioned conductor is that heterogeneous double-level-metal drawing forms, and preferred internal layer is an aluminium conductor, the outer copper conductor that adopts, and two-layer conductor organically combines and guarantees the electric energy of cable, has saved the copper resource, has reduced cost.
Above-mentioned carrying lotus strand structure is made, and preferably three above insulated wire cores improve the tensile strength of whole cable around stranding together.Obturator adopts non-absorbent material to fill and gets final product.
The beneficial effects of the utility model are compared with the prior art: the utility model construction of cable is rationally simple, and cost is low, the tensile strength height, and anticorrosion ability is good, and accommodative ability of environment is strong, reliable operation; Cable has good shielding properties, is suitable for safety simultaneously, and the transmission line that can be widely used under the particular surroundings in the large-engineerings construction such as petrochemical industry, medicine, iron and steel is installed.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1. conductor 2. carries lotuses 3. insulation 4 obturators 5. lapping layers 6. aluminum plastic composite belt longitudinal coverings 7. inner sheaths 8. armours 9 oversheaths 10 restrictive coatings.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Shown in Figure 1, the utility model cable is formed cable core by carrying lotus 2 with around many eradications edge core stranding of carrying lotus 2; Wherein, insulated wire cores is made of the conductor 1 that outer wall coats teflon insulation 3, carrying lotus 2 adopts strand structure to make, the carrying lotus extrudes polytetrafluoroethylene restrictive coating 10 outward, conductor 1 is drawn by aluminium and copper double-level-metal and forms, aluminium conductor places copper conductor inside, and is the center of every eradication edge core; Cable core places in the obturator 4, obturator 4 outer wrapped successively from inside to outside lapping layers 5, after constituting aluminum plastic composite belt longitudinal covering 6, vertical alclad plastic composite strip extrudes in polyamides inner sheath 7 armour 8 of wrapped steel band braiding in the middle of polyamides inner sheath 7 and polyamides oversheath 9.
Claims (5)
