Description
Technical field
It the utility model is related to field of cables, and in particular to a kind of power 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 generally use wire ferrule bundle admittedly
It is fixed, it is on the one hand not attractive in appearance enough, it is difficult that searching is walked when repairing certain cable therein after a plurality of cable bundle on the other hand
To wasting time and energy.
Utility model content
The purpose of this utility model is to provide a kind of function admirable and beneficial to the power cable of line patrolling maintenance.
The utility model adopts the following technical scheme that：
A kind of power cable, it includes several conductors, and each conductor includes the wire, wrapped outside wire at middle part
The ceramic fireproof composite tape layers of side and wrapped the first mica belt on the outside of ceramic fireproof composite band；If
Cladding inner restrictive coating forms cable core on the outside of dry conductor, and petroleum jelly is filled between conductor and inner restrictive coating；On the outside of inner restrictive coating according to
Secondary wrapped second mica tape, alkali-free glass fibre band and armored steel wire layer, outermost are provided with external sheath layer.The outer shield
It is provided with the outside of jacket layer along the identification strip band in conductor direction, link slot and corresponding with link slot connects boss.
Further, the section of the 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 8.
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 link slot is that section is semicircle, and the connection boss is adapted with link slot.
Further, the link slot and connection boss are two, are disposed in the circumference of external sheath layer.
Further, the identification strip band is four and is arranged between link slot and connection boss.
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, multilayer mica tape and wrapped each layer synergy, effectively
Fireproofing of cable performance is improved, improves security performance.Outer layer is provided with link slot and connection boss, can be smoothed out with the fingers along each in wiring
The identification strip band of individual circuit, in addition surface, is more beneficial for overhauling and safeguards.
Brief description of the drawings
Fig. 1 is cross section structure schematic diagram of the present utility model.
Wherein, 1 ceramic fireproof composite tape layers, 2 first mica belts, 3 inner restrictive coatings, 4 petroleum jellys, 5 second clouds
Master tape, 6 alkali-free glass fibre bands, 7 armored steel wire layers, 8 external sheath layers, 9 identification strip bands, 10 link slots, 11 connection boss.
Embodiment
With reference to shown in Fig. 1, a kind of power cable, it includes several conductors, each wire of the conductor including middle part,
Wrapped ceramic fireproof composite tape layers 1 on the outside of wire and wrapped in the outside of ceramic fireproof composite band 1
First mica belt 2；Cladding inner restrictive coating 3 forms cable core on the outside of several conductors, and oil is filled between conductor and inner restrictive coating 3
Cream 4；The outside of inner restrictive coating 3 wrapped second mica tape 5, alkali-free glass fibre band 6 and armored steel wire layer 7 successively, outermost is set
It is equipped with external sheath layer 8；The outside of external sheath layer 8 is provided with along the identification strip band 9 in conductor direction, link slot 10 and with connecting
Connection boss 11 corresponding to access slot 10.
First mica tape and the second mica tape are three-in-one fluorophlogopite belt, can not only improve conductor and conductor
Between insulation effect, can more effectively improve fire resisting and the fire protecting performance of cable.Petroleum jelly can play moistureproof and insulation
Effect, prevents the mica moisture absorption from causing decreasing insulating.Armored steel wire layer has excellent heat dispersion and mechanical performance.Alkali-free
Glass fiber tape has the advantages that temperature resistant grade height, good insulation preformance, resistance to corrosion are strong.
The section of the wire is circle, and it is enclosed for fan-shaped copper cash 12 by some sections and formed.Preferably, it is described
The quantity of copper cash 12 is 8, and each copper section is 1/8th circles.By the selection to copper section, strands are avoided
The problem of resistivity brought is high.
The inner restrictive coating 3 forms for PVC insulating tapes are wrapped.The external sheath layer 8 for low smoke, zero halogen polyethylene extrudes and
Into.
The link slot 10 is that section is semicircle, and the connection boss 11 is adapted with link slot 10.The link slot
10 and connection boss 11 be two, be disposed in the circumference of external sheath layer 8.Cable can by link slot and connection boss
It to complete connection with cable adjacent thereto, can smooth out with the fingers along whole circuit, avoid circuit chaotic, broken down in a certain bar cable
When, maintenance personal is easily found faulty cable.
The identification strip band 9 is four and is arranged between link slot 10 and connection boss 11.Identification strip band is arranged on four
On individual direction, search and distinguish beneficial to maintainer.It with color and section is semicircular boss that the identification strip band, which is,.Institute
The radius for stating identification strip band is less than the connection boss.
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.
