Abstract
The utility model relates to a multi-core low-voltage power cable with shielding performance. The multi-core low-voltage power cable with the shielding performance comprises a cable core. The cable core is formed by intertwisting three insulated wire cores. A liner layer is extruded outside the cable core. Shielding conductors are wound outside the liner layer. A sheath layer is extruded in the outermost layer of the cable core. The insulated wire core comprises main conductors and an insulated layer extruded outside the main conductors. The multi-core low-voltage power cable with shielding performance has the following characteristics that first, the external electromagnetic interference is avoided; second, the multi-core low-voltage power cable with shielding performance has a mechanical protection effect; third, the outer diameter of the cable is small; and fourth, materials are saved.
Description
Technical field
The utility model belongs to the power cable field, is specifically related to a kind of multicore lv power cable with shielding properties.
Background technology
Concerning low-voltage cable, consider electromagnetic shielding, the electromagnetic field in the cable and extraneous electromagnetic field are isolated, be very important.Development along with electronic technology, instrument and meter and electronic circuit thereof have obtained promptly to increase, lower in working order, electromagnetic field is more and more responsive to external world for they, this requires to strengthen the antijamming capability of instrument and circuit itself thereof on the one hand, on the other hand also to external world the electromagnetic field in the certain frequency scope control; When the cable transmission current imbalance, cable itself is a large electromagnetic field generating source, therefore cable is shielded, and can improve the cable quality undoubtedly, makes its interference signal output that neither cable can be produced, and also can prevent the input of external interference.Increasing user is to 1 kV cable in recent years, proposed to have the requirement of shielding layer structure, this interference free performance that 1 kV cable is described is paid attention to by numerous users and designer, and at present lv power cable adopt with ground core and master core simultaneously the version of twisted synthesizing cable can not finish cable is played electromagnetic shielding action.
The utility model content
The purpose of this utility model provides a kind of interference with anti-external electromagnetic, has the mechanical protection effect, low price, the easy lv power cable of processing.
A kind of multicore lv power cable with shielding properties described in the utility model comprises cable core, and its cable core extrudes inner covering by stranded the forming of some eradication edge cores outside cable core, twine shielded conductor outside inner covering, extrudes oversheath at the outermost layer of cable core; Described insulated wire cores is by leading body and be extruded in the outer insulating barrier of leading body and consist of.
Described insulated wire cores is three.
Described shielded conductor is that wire combination of the same type forms with leading body by many, and the total cross section of shielded conductor is taken 1/2nd of body as the leading factor, and covers the 80%-100% of inner covering circumference.
The beneficial effects of the utility model are:
The utility model is changed into the ground wire of low-voltage cable and is wrapped on the main line cable core by the insulated wire cores form, and between ground core and main line cable core, extrude one deck inner covering, make and the utlity model has following characteristics: the one, avoid the interference of external electromagnetic, make the stable effectively transmission of electric energy, avoid the unstable damage that causes power consumption equipment of delivery of electrical energy, the 2nd, have the mechanical protection effect, shielded conductor double make ground wire in, and serve as the metallic sheath of cable, when being subject to the external force infringement, cable can in time protect master core injury-free; The 3rd, the outside diameter of cable diminishes, the ground core is no longer as insulated wire cores and master core together stranding, but be dispersed on the main line cable core, saved the cable core space, thereby reduced the outside diameter of cable, the 4th, save material, follow the external diameter of cable to reduce, follow-up outer sheath material consumption also has corresponding minimizing.This processes is easy, and material also is easy to obtain, low price, thus save manufacturing cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of multicore lv power cable with shielding properties described in the utility model comprises cable core, its cable core three thoroughly does away with stranded the forming of edge core, outside cable core, extrude inner covering 3, at inner covering 3 outer winding shielded conductors 4, extrude oversheath 5 at the outermost layer of cable core; Described insulated wire cores is by leading body 1 and be extruded in the outer insulating barrier 2 of leading body 1 and consist of.
Shielded conductor 4 many of employings and leading body wire left-hand of the same type described above are wrapped on the inner covering 3, and the total cross section of shielded conductor 4 is taken 1/2nd of body as the leading factor, and covers the 80%-100% of inner covering 3 circumference.
The utility model provides a kind of multicore lv power cable with shielding properties; the above only is preferred implementation method 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.
