Abstract
The invention discloses a heatproof flexible cable which mainly comprises nickel cable cores, a filling layer, an aluminum strip package wrapping layer, a sheath layer and copper cable cores. Three sets of nickel cable cores are extruded in the filling layer in an abreast mode, each nickel cable core comprises a nickel conductor, an insulation layer and an aluminum strip shielding layer, and the aluminum strip wrapping layer is wrapped on the filling layer. The heatproof flexible cable is widely applied to iron and steel plants, copper smelting plants, continuous casting machines and power or control lines of thermal power plants. The heatproof flexible cable has excellent performance of resistance to high temperature and radiation and further has the advantages of being resistant to electromagnetic interference and good in shielding performance.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of heat-resisting flexible cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the field such as power or control circuit of steel plant, copper smelting plant, conticaster and thermal power plant turbine-boiler, the requirement of the useful life to cable, anti-electromagnetic interference, shielding properties and resisting radiation interference aspect of performance is all high especially, only meets the requirements, and could improve in these fields the fail safe while manufacturing.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of high temperature resistant radiance, the heat-resisting flexible cable of advantages of good shielding performance.
The present invention takes following technical scheme to realize: a kind of heat-resisting flexible cable, it mainly comprises nickel cable core, packed layer, aluminium strip belting layer, restrictive coating and copper cable core, described packed layer inside is extruded with three groups of nickel cable cores side by side, described nickel cable core is followed successively by nickel conductor, insulating barrier and aluminium strip screen from inside to outside, and described packed layer is wrapped with one deck aluminium strip belting layer.
Described copper cable core is two, is arranged on uniformly in described packed layer, and every cable core is all made up of copper conductor and chain armour.
In described restrictive coating, be extruded with a copper body heating wire.
The present invention has following beneficial effect in sum: the present invention is widely used in power or the control circuit of steel plant, copper smelting plant, conticaster and thermal power plant turbine-boiler, there is good high temperature resistant radiance, and it is strong to have anti-electromagnetic interference, the advantage of advantages of good shielding performance.
Brief description of the drawings
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, nickel conductor; 2, insulating barrier; 3, aluminium strip screen; 4, packed layer; 5, aluminium strip belting layer; 6, restrictive coating; 7, copper cable core; 8, copper body heating wire.
Embodiment
As shown in Figure 1, a kind of heat-resisting flexible cable, it mainly comprises nickel cable core, packed layer 4, aluminium strip belting layer 5, restrictive coating 6 and copper cable core 7, described packed layer 4 inside are extruded with three groups of nickel cable cores side by side, described nickel cable core is followed successively by nickel conductor 1, insulating barrier 2 and aluminium strip screen 3 from inside to outside, and described packed layer 4 is wrapped with one deck aluminium strip belting layer 5.
In embodiment: described copper cable core 7 is two, be arranged on uniformly in described packed layer 4, every cable core is all made up of copper conductor and chain armour.
In described restrictive coating 6, be extruded with a copper body heating wire 8.
This cable permission bending radius is not less than 20 times of the outside diameter of cable, and flexibility is strong.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
