In, plastic insulation material is usually cross-linking polyethylene materials, and the power cable that the material is made its operating temperature also has at 90 DEG C
Using the PVC materials that operating temperature is 70 DEG C, sheath material is usually PVC materials, and the material has low cost, fire-retardant etc. excellent
Point.
In addition to power cable, cable and power cable also with signal transfer functions are used in various occasions in the lump,
In order that signal cable can not influenceed by the electromagnetic interference that power cable is produced in use, signal cable mainly has two
The technology of kind：
1st, using fiber unit as signal cable transmission medium, because fiber unit will not be subject to any electromagnetic interference
Influence；
2nd, using copper conductor as signal transmission medium, in order to ensure that such cable is not influenceed by electromagnetic interference, electricity
Layer of metal screen layer is provided with cable.
In the prior art, the power cable and signal cable for using separately are laid, only there is a kind of function, overall weight
Weight, manufacture and construction cost are higher, and repeatedly lay, and install inconvenience.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of multicore signal composite electric electricity
Cable, power cable and signal cable are compounded in a cable, solve two kinds of cables in the prior art need separately to lay and
The problem of manufacture, while also to solve existing various cable overall weight weights, bulky problem.
According to the utility model provide technical scheme, the multicore signal composite power cable, it is characterized in that：Including dynamic
Line of force core, holding wire cable core and ground heart yearn, power wire core and ground heart yearn are stranded using juxtaposition, heart yearn and power on ground
The gap location of core places some groups of holding wire cable cores；Filled out in the gap of the power wire core, holding wire cable core and ground heart yearn
Enter packed layer, wrapped non-woven fabrics, sets oversheath on the outside of non-woven fabrics on the outside of packed layer.
Further, the power wire core includes power wire core, and power line insulating layer is extruded on the outside of power wire core.
Further, the holding wire cable core includes three signal cores, in outside after three signal cores are stranded side by side
Wrapped aluminium foil strip, weaves holding wire core metal braiding layer on the outside of aluminium foil strip.
Further, the signal core includes holding wire conductor, and signal line insulating layer is extruded on the outside of holding wire conductor,
Holding wire core metal braiding layer is woven on the outside of signal line insulating layer.
Further, described ground heart yearn includes ground cored wire conductor, and ground core insulation is extruded on the outside of ground cored wire conductor.
Further, the setting quantity of the holding wire cable core is at most consistent with ground heart yearn and power wire core quantity.
Holding wire cable core is arranged on power wire core and ground heart yearn by multicore signal composite power cable described in the utility model
In gap, realize signal core and be combined, reduce the external diameter of cable, reduce the weight of cable, reduce and lay number of times,
Reduce production and laid down cost.
Brief description of the drawings
Fig. 1 is the structural representation of multicore signal composite power cable described in the utility model.
Description of reference numerals：Power line conductor 1, power line insulating layer 2, holding wire conductor 3, signal line insulating layer 4, signal
Core wire sheathing 5, aluminium foil strip 6, signal cable core metal braiding layer 7, cored wire conductor 8, core insulation 9, filling
Layer 10, nonwoven layer 11, oversheath 12.
Specific embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1：Multicore signal composite power cable described in the utility model include power wire core, holding wire cable core and
Ground heart yearn, power wire core and ground heart yearn are stranded using juxtaposition, if the gap location in ground heart yearn and power wire core is placed
Dry group holding wire cable core, can at most place the holding wire cable core consistent with ground heart yearn and power wire core quantity；In the power line
Packed layer 10 is inserted in the gap of core, holding wire cable core and ground heart yearn, in the wrapped non-woven fabrics 11 in the outside of packed layer 10, in non-woven fabrics
11 outsides set oversheath 12.
The power wire core includes power wire core 1, and power line insulating layer 2 is extruded in the outside of power wire core 1.
The holding wire cable core includes three signal cores, in the wrapped aluminium foil strip in outside after three signal cores are stranded side by side
