The utility model has the advantages of structural design is reasonable, shielding property good and long service life.

Description

A kind of high-performance anti-nuclear explosion special cable of emp

Technical field

The utility model relates to field of cables, particularly relates to a kind of high-performance anti-nuclear explosion special cable of emp.

Background technology

Nuclear explosion is produced emp ripple, and to have amplitude big, frequency spectrum width, action time is short, scope is wide, inefficacy or the damage of cable transmission function can be caused equally, safe and reliable for ensureing cable transmission, it is necessary to cable to be carried out the shielding of the high frequency ripple in wide frequency range and low-frequency magnetic shielding, with the metallic substance of high conductivity and high permeability, cable shield is got up. Current existing electromagnetic pulse resistant cable can not reach high performance requirements on shielding construction is arranged He in selection, and shielding efficiency only reaches about 60dB, and shielding level is many, and volume is big, Heavy Weight, and the soft bending property of cable is poor.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of high-performance anti-nuclear explosion special cable of emp.

The utility model takes following technical scheme to realize: a kind of high-performance anti-nuclear explosion special cable of emp, it comprises cable body, described cable body comprises conductor, enhancement Layer, the first screen layer and oversheath, and described cable body inside is provided with multiple conductor; Described conductor external parcel one layer of enhancement Layer; And a layer insulating is set outside described enhancement Layer; Described insulation layer, enhancement Layer and conductor form cable core jointly; Described cable body inside is provided with multiple cable core; One layer of first screen layer is closely extruded outside described cable core; One layer of the 2nd screen layer is extruded outside described first screen layer; One layer of the 3rd screen layer is extruded outside described 2nd screen layer; One layer of the 4th screen layer is extruded outside described 3rd screen layer; One layer of oversheath is closely extruded outside described 4th screen layer.

Above-mentioned a kind of high-performance anti-nuclear explosion special cable of emp, described first screen layer compound copper-plastics band is overlapping wrapped and becomes.

Above-mentioned a kind of high-performance anti-nuclear explosion special cable of emp, described 2nd screen layer nickel plating copper wire weaves and becomes.

Above-mentioned a kind of high-performance anti-nuclear explosion special cable of emp, described 3rd screen layer is that alloy soft magnetic iron oxygen band is made.

The utility model has following useful effect in sum: the utility model has the advantages such as reasonable in design, advantages of good shielding performance and long service life, described first screen layer compound copper-plastics band is overlapping wrapped and becomes, shielding construction is simplified light, shielding thickness reduces, cable weight saving, is convenient to install and use.

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, cable body; 2, conductor; 3, enhancement Layer; 4, insulation layer; 5, the first screen layer; 6, the 2nd screen layer; 7, the 3rd screen layer; 8, the 4th screen layer; 9, oversheath.

Embodiment

As shown in Figure 1, a kind of high-performance anti-nuclear explosion special cable of emp, it comprises cable body 1, and described cable body 1 comprises conductor 2, enhancement Layer 3, first screen layer 5 and oversheath 9, and described cable body 1 inside is provided with multiple conductor 2; Described conductor 2 external parcel one layer of enhancement Layer 3; And a layer insulating 4 is set outside described enhancement Layer 3; Described insulation layer 4, enhancement Layer 3 and conductor 2 form cable core jointly; Described cable body 1 inside is provided with multiple cable core; One layer of first screen layer 5 is closely extruded outside described cable core; One layer of the 2nd screen layer 6 is extruded outside described first screen layer 5; One layer of the 3rd screen layer 7 is extruded outside described 2nd screen layer 6; One layer of the 4th screen layer 8 is extruded outside described 3rd screen layer 7; One layer of oversheath 9 is closely extruded outside described 4th screen layer.

Described conductor 2 external parcel one layer of enhancement Layer 3 can effectively protect conductor 2, effectively prevents conductor 2 because there is the situation of fracture by external force, effectively extends the work-ing life of conductor 2; Described first screen layer 5 compound copper-plastics band is overlapping wrapped and becomes, described 2nd screen layer 6 nickel plating copper wire weaves and becomes, described 3rd screen layer 7 is made for alloy soft magnetic iron oxygen band, not only making shielding construction simplify light, shielding thickness reduces, cable weight saving, it is convenient to install and use, and can effectively prevent external electromagnetic signal from cable body 1 is caused the situation of interference so that it is can also normally use under severe environment so that it is working process is more stable.

The above is embodiment of the present utility model, therefore all equivalences done according to the structure described in the utility model application range, feature and principle change or modify, and are included within the scope of the utility model patent application.
