Description

A kind of improved cable
Technical field
It the utility model is related to a kind of improved cable.
Background technology
Power cable is the cable for transmitting and distributing electric energy, and power cable is usually used in Urban Underground power network, power station Lead line, industrial and mining enterprises' in-line power and mistake river sea submarine transmission line.In power circuit, cable proportion just gradually increases Add.
Power cable can be related to the arranged in parallel of a plurality of cable in placement process, and the generally use wire ferrule of the communications cable enters Row bundled fixed, it is on the one hand not attractive in appearance enough, on the other hand, after a plurality of cable bundle, when repairing certain cable therein very Hardly possible finds trend, wastes time and energy.
Utility model content
The purpose of this utility model is to provide the cable that a kind of resistivity is low, shield effectiveness is good.
The utility model adopts the following technical scheme that:
A kind of improved cable, it includes several the first conductors, cladding inner restrictive coating structure on the outside of several first conductors Into cable core, petroleum jelly is filled between the first conductor and inner restrictive coating;Inner restrictive coating has been orderly arranged outside each alkali-free glass fibre band Layer, metal sheath layer and external sheath layer.
Wherein, the metal sheath layer includes inner metal layer, outer metal level and connection inner metal layer and outer metal level Connect band, the inner metal layer, outer metal level and connect band are enclosed to form threading passage, and the is provided with the threading passage Two conductors, asbestos cord is filled between second conductor and threading passage.
Wherein, first wire of first conductor including middle part, the wrapped ceramic fire prevention on the outside of the first wire are resistance to Fiery composite tape layers and the wrapped mica belt on the outside of ceramic fireproof composite band.
Wherein, second conductor includes the second wire, the polyvinyl chloride insulation being arranged on the outside of the second wire at middle part Layer.
Further, the section of first wire is circle, and it is enclosed for fan-shaped copper cash by some sections and formed.
Further, the quantity of the copper cash is eight.
Further, the inner restrictive coating forms for PVC insulating tapes are wrapped.
Further, the external sheath layer is extruded for low smoke, zero halogen polyethylene and formed.
Further, the material of the inner metal layer, outer metal level and connect band is steel.
Further, the connect band is set along cable core, and quantity is four, and the connect band is by inner metal layer and outer metal Space uniform between layer is divided into four threading passages.
The beneficial effects of the utility model are:Enclose to form conductor by several fan-shaped copper wires, twisted compared with stranded copper wire Closing has lower resistivity, and electric conductivity is more preferable.Petroleum jelly, alkali-free glass fibre belt and metal sheath layer joint are made With effectively improving fireproofing of cable and security performance.Metal sheath layer is bilayer and is provided with threading passage, shielding electromagnetism effect Should, avoid impacting the communications cable in threading passage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 inner restrictive coating, 2 petroleum jellys, 3 alkali-free glass fibre belts, 4 external sheath layers, 5 inner metal layers, 6 outer metals Layer, 7 connect bands, 8 threading passages, 9 asbestos cords, 10 ceramic fireproof composite tape layers, 11 mica belts, 12 second wires, 13 polyvinyl chloride insulation layers, 14 copper cash.
Embodiment
With reference to shown in Fig. 1, a kind of improved cable, it includes several the first conductors, is wrapped on the outside of several first conductors Cover inner restrictive coating 1 and form cable core, petroleum jelly 2 is filled between the first conductor and inner restrictive coating 1;Inner restrictive coating 1 is orderly arranged outside each There are alkali-free glass fibre belt 3, metal sheath layer and external sheath layer 4.
The metal sheath layer includes inner metal layer 5, outer metal level 6 and the company of connection inner metal layer 5 and outer metal level 6 Tape splicing 7, the inner metal layer 5, outer metal level 6 and connect band 7 enclose to form threading passage 8, are set in the threading passage 8 There is the second conductor, asbestos cord 9 is filled between second conductor and threading passage 8.
The first wire, the wrapped ceramic fireproof on the outside of the first wire that first conductor includes middle part are compound Belt 10 and the wrapped mica belt 11 in the outside of ceramic fireproof composite band 10;The section of first wire is circle Shape, it is enclosed for fan-shaped copper cash 14 by some sections and formed.Preferably, the quantity of the copper cash 14 is eight.
Petroleum jelly can play a part of moistureproof and insulation, prevent the cable core moisture absorption from causing decreasing insulating.Steel wire fills armour Layer has excellent heat dispersion and mechanical performance.Alkali-free glass fibre band has temperature resistant grade height, good insulation preformance, anticorrosive The advantages that ability is strong.
The section of first wire is circle, and it is enclosed for fan-shaped copper cash 14 by some sections and formed.Preferably, The quantity of the copper cash 14 is 8, and the section of each copper cash 14 is 1/8th circles.By the selection to copper section, avoid The problem of resistivity that strands are brought is high.
Second conductor includes second wire 12 at middle part, is arranged on the polyvinyl chloride insulation layer in the outside of the second wire 12 13.Second wire 12 is that copper wire and iron wire are twisted.
The inner restrictive coating 1 forms for PVC insulating tapes are wrapped.The external sheath layer 4 for low smoke, zero halogen polyethylene extrudes and Into.
The material of the inner metal layer 5, outer metal level 6 and connect band 7 is steel.The connect band 7 is set along cable core, Quantity is four, and the space uniform between inner metal layer 5 and outer metal level 6 is divided into four threading passages by the connect band 7 8。
Metal sheath layer is double-decker, and the second conductor has been placed between two layers, and being connected band between the second conductor separates, It is separately positioned in different threading passages, threading passage is supplied to the environment of one shielding of the second conductor, can not only shield Cable core, while the galvanomagnetic-effect between the second conductor can be shielded.Second conductor acts not only as electric power cable use, also may be used Used as the communications cable.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations;Although with reference to foregoing reality Example is applied the utility model is described in detail, it will be understood by those within the art that:It still can be to preceding State the technical scheme described in embodiment to modify, or equivalent substitution is carried out to which part technical characteristic;And these are repaiied Change or replace, the essence of appropriate technical solution is departed from the spirit and scope of the utility model embodiment technical scheme.
