Abstract
The utility model discloses a magnetostatic shielding power cable, which comprises a cable core, wherein the cable core is formed by twisting a plurality of insulated wire cores; each insulated wire core is formed by a conductor and an insulating layer extruded outside the conductor; the gap of the cable core is provided with filling ropes, an inner lining layer is wrapped outside the cable core, and an outer sheath is extruded on the outermost layer of the cable core; and a steel-tape armoring layer with the thickness of 0.1-0.2mm is coated between the inner lining layer and the outer sheath, and two flat copper wires with the thickness of 0.8mm are parallelly arranged in the steel-tape armoring layer. According to the magnetostatic shielding power cable, the steel tape and the flat copper wires are adopted for magnetostatic shielding, with regard to the transmission of low-frequency cables, the shielding effect is good since the magnetic permeability of steel materials is high, so that the magnetic flow generated by the cable is limited inside the strong magnetic shielding body; and compared with the copper-wire shielding cable in the prior art, the magnetostatic shielding power cable has the advantages of high production speed and low cost, and has certain external pressure resistance.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of magnetic shielding power cable.
Background technology
In the equipment such as electronic message unit or home appliance, exist the frequency converter be arranged in this equipment etc. to become the generation source of Electromagnetic Interference, the Electromagnetic Interference that this generation source produces is carried out radiation by cable, thereby the miscellaneous equipment of periphery is caused the problem of the baneful influences such as misoperation.
At present, shielding type cable is mainly used in the fields such as electric power transfer and signal of communication reception, and the general shielding type cable of prior art has adopted proof copper-wire braided or the braiding of Copper Foil line etc., its speed of production is slower, production process is complicated, because the copper price is comparatively expensive, has virtually increased production cost.
The utility model content
Technical problem to be solved in the utility model provides that a kind of speed of production is very fast, and cost is lower, and shield effectiveness is better, has again the magnetic shielding power cable of certain opposing ambient pressure effect simultaneously.
A kind of magnetic shielding power cable described in the utility model comprises cable core, and its cable core is to form by some insulated wire cores are stranded; Described insulated wire cores is by conductor and be extruded in the outer insulating barrier of conductor and consist of; Be provided with gasket for packing in the cable core gap, the outer wrapping lining-layer of cable core, the cable core outermost layer extrudes oversheath; Coated steel band armour between inner covering and oversheath, the inner also 2 flat copper silk of parallel placement of described steel-tape armouring layer.
Further improve, the thickness of described steel-tape armouring layer is 0.1-0.2mm.
Further improve, the thickness of described flat copper silk is 0.8mm again.
The beneficial effects of the utility model are:
The utility model cable has adopted 0.1-0.2mm thickness steel band wrapped in the cable core outside, and at 2 flat copper silks of the parallel placement of steel band internal layer, steel band and flat copper silk have formed the effect of magnetic shielding jointly, transmission for low-frequency cable, because the unit permeance of Steel material is higher, so shield effectiveness is better, magnetic flux that this cable produces is limited to the inside of strong magnetic shield, compare with brass wire shielding cable in the prior art, its speed of production is higher, cost is low, has the effect of certain opposing ambient pressure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of magnetic shielding power cable described in the utility model comprises cable core, and its cable core is to form by some insulated wire cores are stranded; Described insulated wire cores is by conductor 1 and be extruded in the outer insulating barrier 2 of conductor 1 and consist of; Be provided with gasket for packing 3 in the cable core gap, the outer wrapping lining-layer 4 of cable core, the cable core outermost layer extrudes oversheath 7; Coating thickness between inner covering 4 and oversheath 7 is the steel-tape armouring layer 6 of 0.1-0.2mm, the flat copper silk 5 that described steel-tape armouring layer 6 inner also two thickness of parallel placement are 0.8mm.
The concrete application approach of the utility model is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
