Abstract
The utility model discloses a combination cable which comprises a plurality of electrically-assembled cable cores, a plurality of power cable cores, a plurality of metal shielding layers, a plurality of packing belts and a plurality of sheathes, wherein the plurality of electrically-assembled cable cores are arranged at the center, and the outer layers of the electrically-assembled cable cores are packed with the metal shielding layers; the plurality of power cable cores are arranged around the outer circumferences of the metal shielding layers; and the outer layers of the power cable cores are sequentially provided with the packing belts and the power cable cores which are made from silicon rubber. After conventional cable distributing mode is optimized, compared with a '-'-shaped distribution structure, the power cable cores are arranged around the outer circumferences of the metal shielding layers, so that the intensity of the interference to the electrically-assembled cable cores caused by a electric field is reduced, the signal transmission capability is strengthened, and a better signal transmission effect can be obtained due to a concentric and symmetrical structure when the circle center of the cross section of each power cable core is arranged on the concentric circle of each metal shielding layer particularly.

The utility model content
The purpose of this utility model provides a kind of easy for installation, interference of laying easily, can reducing electric field, the combination cable that the transmission signals ability is strong.
The technical scheme that realizes the utility model purpose is a kind of combination cable, comprises many electric mounting cable cores and power cable core; Also comprise metal screen layer, band and sheath; Described many electric mounting cable cores are positioned at the center, its extexine clad metal screen; Many power cable cores are arranged around the excircle of metal screen layer; The extexine of power cable core sets gradually the sheath of band and silicon rubber material.
Described electric mounting cable core is made up of with extruding in first insulating barrier of the outer field silicon rubber material of first conductor first conductor; Described power cable core is made up of with extruding in second insulating barrier of the outer field silicon rubber material of second conductor second conductor.
Second conductor of the power cable core that first conductor of described electric mounting cable core reaches adopts many 5th kind or the 6th kind of stranded the forming of stranded flexible conductor structure.
Described many power cable cores are arranged around the excircle of described metal screen layer with 1.01～1.04 Haul Rate.
The center of circle in the cross section of described every power cable core is positioned on the concentric circles with the cross section of metal screen layer.
The outer surface of first insulating barrier of described many electric mounting cable cores and second insulating barrier of power cable core scribbles talcum powder.
Described many electric mounting cable cores comprise communication cable, control cable, computer cable, cable for measuring temperature.
After having adopted technique scheme, the utility model has brought following beneficial effect: (1) the utility model has been optimized traditional winding displacement mode, many power cable cores are arranged around the excircle of metal screen layer, structure with respect to word order, reduced electric field to electric mounting cable core interference intensity, strengthened the ability of transmission signals, particularly when the center of circle in the cross section of power cable core was positioned on the concentric circles with the cross section of metal screen layer, this concentric symmetrical structure can obtain better signal transmission effect.
What (2) insulating barrier of electric mounting cable core of the present utility model and power cable core and sheath adopted is silicon rubber, improved the softness characteristics and the characteristic such as anticorrosion, grease proofing, high temperature resistant, low temperature resistant of cable, be particularly suitable for occasion such as metallurgical car, boiler, power plant and equipment and use.
(3) electric mounting cable core of the present utility model and power cable core conductor adopt the 5th kind or the 6th kind of stranded forming of stranded flexible conductor structure meeting GB/T3956, make the bending property of removal cable good, improved the flexibility of combination cable.
(4) outer surface of the insulating barrier of electric mounting cable core of the present utility model and power cable core scribbles talcum powder, and this structure can reduce the friction between cable core, the slip between the increase cable core, has further strengthened the crooked sliding of combination cable.
