Abstract
The utility model proposes a kind of double shield controlling cable, it is characterised in that including：Center conductor and the band being coated on successively outside the center conductor, copper strips, bed course, steel-tape armouring and oversheath, the steel-tape armouring is provided with some copper wires between the inboard outside bed course, it is inboard with bed course outside and longitudinally disposed along length of cable that the copper wire is close to the steel-tape armouring, the center conductor includes the bundle conductor being made up of a plurality of wire, and the wire includes copper conductor and the insulating barrier being coated on outside copper conductor.The electric property of the utility model cable is in addition to all electric properties for meeting conventional control cable; mainly prominent performance is that the anti-forceful electric power of double shield does the protective effect of sorrow performance and steel-tape armouring to cable; enable cable to resist certain pressure and pulling force, have good protective effect to cable in the place such as the tunnel laid, cable duct, soil, many gravels, inflammable, perishable.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, and in particular to a kind of double shield controlling cable.
Background technology
It is 450V/750V and following control, monitoring loop and protection circuit that controlling cable, which is used for ac rated voltage U0/U,
Etc. occasion, these occasions often face the use environment of complexity, and are disturbed with forceful electric power.Existing control cable product standard
And have shield type and armouring kind control cable in specification, under use environment increasingly complicated and changeable, the screen of existing cable product
Cover effect and cable intensity needs further reinforcement, existing in the market there are no the screened cable knot that shielding and armouring are combined
Structure.
Utility model content
To overcome the defect in the presence of prior art, the utility model proposes a kind of double shield controlling cable, its is specific
Technology contents are as follows：
A kind of double shield controlling cable, it includes：Center conductor and the band being coated on successively outside the center conductor, copper
Band, bed course, steel-tape armouring and oversheath, the steel-tape armouring are provided with some copper wires, the copper between the inboard outside bed course
Silk be close to the steel-tape armouring it is inboard with it is on the outside of bed course and longitudinally disposed along length of cable, the center conductor by a plurality of including being led
The bundle conductor of line composition, the wire includes copper conductor and the insulating barrier being coated on outside copper conductor.
In one or more embodiments of the present utility model, 3 to 61, the wire.
In one or more embodiments of the present utility model, the conductor cross-section is rounded, and it includes a center conductor
Tightly surround some peripheral wires of the center conductor.
In one or more embodiments of the present utility model, the copper wire is at least 4, in circumferential uniform arrangement.
In one or more embodiments of the present utility model, the oversheath and insulating barrier are PVC.
The beneficial effects of the utility model are：
The electric property of cable is in addition to all electric properties for meeting conventional control cable, and mainly prominent performance is double
Shield anti-forceful electric power and do the protective effect of sorrow performance and steel-tape armouring to cable, be specifically, inside and outside nested copper strips and steel-tape armouring
Double shield effect is realized, it is ad hoc in respect of four cooperation steel-tape armourings in this patent simultaneously as the electric conductivity of steel band is poor
Copper wire, to strengthen the conduction property of steel band shielding so that the shielding properties of steel band is greatly reinforced.In addition, steel-tape armouring is another
Function just protects cable so that cable can resist certain pressure and pulling force, in the tunnel laid, cable duct, soil, many gravels
The place such as stone, inflammable, perishable has good protective effect to cable, and allowing cable can apply to exist forceful electric power and do sorrow and cable makes
With the place that environment is complicated.
Brief description of the drawings
Fig. 1 is the structural representation of double shield controlling cable of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1, application scheme is further described：
A kind of double shield controlling cable, it includes：Center conductor and the band 6 being coated on successively outside the center conductor,
Provided with four in circumferentially between copper strips 5, bed course 4, steel-tape armouring 2 and oversheath 1, the inboard outside bed course 4 of the steel-tape armouring 2
The copper wire 3 uniformly arranged, it is inboard with being set along length of cable on the outside of bed course 4 and longitudinally that the copper wire 3 is close to the steel-tape armouring 2
Put, the center conductor includes the bundle conductor being made up of a plurality of wire, the wire includes copper conductor 8 and is coated on copper conductor 8
Outer insulating barrier 7；The oversheath 2 and insulating barrier 7 are PVC.In the present embodiment, the wire has seven, and the wire is cut
Face is rounded, and it includes a center conductor and six peripheral wires for tightly surrounding the center conductor；Wire of the present utility model
Bar number can be 7,37,61 etc., depending on implementation demand.
Inside and outside nested copper strips 5 and steel-tape armouring 2 realize double shield effect, simultaneously as the electric conductivity of steel band is poor,
The ad hoc copper wire 3 in respect of four cooperation steel-tape armourings 2 in this patent, to strengthen the conduction property of steel band shielding so that steel band
Shielding properties is greatly reinforced.In addition, another function of steel-tape armouring 2 just protects cable so that cable can resist certain pressure
And pulling force, there is protection well to make to cable in the place such as the tunnel laid, cable duct, soil, many gravels, inflammable, perishable
With allowing cable to can apply to exist forceful electric power and do sorrow and the complicated place of cable use environment.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Deduce, replace with, technology that is approximate or making based on this, improving etc., it is regarded as the protection domain of this patent.
