In power cable field, particularly for the electric wire with information spreading function, be easy in the course of the work be subject to extraneous interference, also to producing electromagnetic radiation around, this has certain influence to the electrical performance of cable, usually all needs the outside clad metal screen at core; Meanwhile, the high temperature of the operational environment of cable conductor, also has a significant impact the current capacity of cable, and this is usually at the restrictive coating that the outside coated employing fire resistant flame retardant material of cable core is made.
But arrange multiple functional layer outside cable core, the construction of cable can be caused complicated, and manufacture process is complicated, increases material cost, and causes the weight of final cable to increase, be not easy to actual laying and the use of cable.
Utility model content
In order to solve the technical problem existed in background technology, the utility model proposes a kind of environmental-protection flame-retardant Anti-interference cable, its structure be simple, advantages of good shielding performance, good flame retardation effect.
A kind of environmental-protection flame-retardant Anti-interference cable that the utility model proposes, comprises cable core, is coated on the lapping layer of described cable core outside, is coated on the flame-retardant layer of lapping layer outside, is coated on the restrictive coating of flame-retardant layer outside; Described cable core forms by multiple conducting wires is stranded, wire comprises the conductor being positioned at middle part and the insulating barrier being coated on conductor outside, conductor forms by many tinned copper wires are stranded, the inner surface of flame-retardant layer is provided with multiple first grooves extended vertically, the first metal coating is provided with in described first groove, restrictive coating inner surface is provided with multiple second grooves extended vertically, is provided with the second metal coating in described second groove, and restrictive coating adopts low-smoke halogen-free polyolefin material to make.
Preferably, described first groove is uniformly distributed at the inner surface of flame-retardant layer.
Preferably, described second groove is uniformly distributed at the inner surface of restrictive coating.
Preferably, the first metal coating and the second metal coating adopt different metal material to make.
Preferably, the first groove and the second groove location are interlocked.
Preferably, described cable core adopts that multiple conducting wires is regular strandedly to be formed.
In the utility model, the environmental-protection flame-retardant Anti-interference cable proposed, cable core outside is coated lapping layer, flame-retardant layer and restrictive coating successively, the inner surface of flame-retardant layer and restrictive coating is respectively equipped with the first groove and the second groove, be provided with metal coating in first groove and the second groove, restrictive coating adopts low-smoke halogen-free polyolefin material to make.In said structure arrangement, on the one hand, the metal coating in the first groove and the second groove can play the effect of screen, prevent external electromagnetic wave interference, on the other hand, metal coating embeds in flame-retardant layer and restrictive coating, simplify cable core internal structure, reduce cable material cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of environmental-protection flame-retardant Anti-interference cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of environmental-protection flame-retardant Anti-interference cable that the utility model proposes.
With reference to Fig. 1, a kind of environmental-protection flame-retardant Anti-interference cable that the utility model proposes, comprises cable core, lapping layer 2, flame-retardant layer 3, restrictive coating 4;
Above-mentioned cable core strandedly to form by seven wires 1 are regular, this stranded mode is layout type the most stable, external force be difficult to change between wire 1 in conjunction with layout, wire 1 comprises the conductor 11 being positioned at middle part, conductor 11 forms by many tinned copper wires are stranded, and tinned copper wire ensure that the softness of cable, and makes conductor corrosion-resistant, the outside coated insulation layer 12 of conductor 11, ensures mutually insulated between conductor 11;
Lapping layer 2 is wrapped outside at above-mentioned cable core, seven wires 1 are strapped in together tightly, it is outside that flame-retardant layer 3 is coated on lapping layer 2, which ensure that the fire resistance of cable, the inner surface of flame-retardant layer 3 is provided with multiple first grooves extended vertically, this first groove is uniformly distributed at the inner surface of flame-retardant layer 3, aluminum metal coating 30 is provided with in first groove, it is outside that restrictive coating 4 is coated on flame-retardant layer 3, it adopts low-smoke halogen-free polyolefin material to make, ensure nontoxic in cable fire and environmentally safe, the inner surface of restrictive coating 4 is provided with multiple second grooves extended vertically, this second groove is uniformly distributed at the inner surface of restrictive coating 4, copper metal coating 40 is provided with in second groove, first groove and the second groove location are interlocked.
In the present embodiment, the environmental-protection flame-retardant Anti-interference cable proposed, cable core outside is coated lapping layer, flame-retardant layer and restrictive coating successively, the inner surface of flame-retardant layer and restrictive coating is respectively equipped with the first groove and the second groove, be provided with metal coating in first groove and the second groove, restrictive coating adopts low-smoke halogen-free polyolefin material to make.In said structure arrangement, on the one hand, the metal coating in the first groove and the second groove can play the effect of screen, prevent external electromagnetic wave interference, on the other hand, metal coating embeds in flame-retardant layer and restrictive coating, simplify cable core internal structure, reduce cable material cost.
In concrete structure design, this first groove is uniformly distributed at the inner surface of flame-retardant layer 3, be provided with aluminum metal coating 30, second groove in first groove to be uniformly distributed at the inner surface of restrictive coating 4, in the second groove, be provided with copper metal coating 40, first groove and the second groove location are interlocked, the radiation produced in cable core work, is caught by aluminum metal coating 30 and copper metal coating 40, thus cannot externally environmental radiation, realize the complementation of shield ranges, the enhancing of shield effectiveness; Equally, outside Electromagnetic Interference also cannot enter cable core; Meanwhile, aluminum metal coating 30 and copper metal coating 40 extend in wire, therefore, greatly limit the eddy current of inducting produced in metal coating, something which increases the current capacity of electric wire.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
