Description
Technical field
The utility model is related to a kind of cable, and especially a kind of compound power cable, belongs to field of cable technology.
Background technology
The plastic power cable that the country is used at present is quite varied, is usually used in the extraction in Urban Underground power network, power station
The submarine transmission line of circuit, the in-line power of industrial and mining enterprises and crossing river and sea.The basic structure of the power cable of the type is by line
Core（Conductor）, insulating barrier, screen layer and the part of protective layer four composition, its cost is relatively low, is adapted to large-scale use.Power cable
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.
There is problems with and shortcoming in prior art：
1st, the power cable and signal cable for using separately are laid, only there is a kind of function, overall weight weight is manufactured and built
If it is relatively costly, and repeatedly lay, inconvenience is installed；
2nd, the signal cable of copper conductor has woven layer of metal screen layer, but totality shielding always coefficient be not it is very low,
Typically all 0.5 or so, still can be influenceed by electromagnetic interference in signals transmission.
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 compound power cable, will
Power cable and signal cable are compounded in a cable, and solving two kinds of cables in the prior art needs what is separately laid and manufacture
Problem, while existing various cable overall weight weights, bulky problem are also solved, and signal cable shielding rejection coefficient
Problem high.
According to the utility model provide technical scheme, the compound power cable, it is characterized in that：Including by some
Master core extrudes sheath, around Baogang on the outside of sheath using the stranded cable core of stranded mode arranged side by side on the outside of cable core
Belt, extrudes outer jacket on the outside of steel belt layer；The master core includes holding wire conductor, and signal is extruded on the outside of wire size line conductor
Line insulating layer, weaves signal conductor screen on the outside of signal line insulating layer, and power line is woven on the outside of signal conductor screen
Core conductor, extrudes power wire core insulating barrier on the outside of power wire core conductor.
Further, packed layer is inserted in the gap of the master core.
Compound power cable described in the utility model, signal core is arranged in power wire core, realizes holding wire
Core is combined, and reduces the external diameter of cable, reduces the weight of cable, reduces and lays number of times, reduces production and laid down cost.
Signal core is arranged in power wire core conductor, improves the shield effectiveness of signal core.
Brief description of the drawings
Fig. 1 is the structural representation of compound power cable described in the utility model.
Description of reference numerals：Holding wire conductor 1, signal line insulating layer 2, signal conductor screen 3, power wire core conductor 4,
Power wire core insulating barrier 5, packed layer 6, sheath 7, steel belt layer 8, outer jacket 9.
Specific embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1：Compound power cable described in the utility model is included by some master cores using stranded side by side
The stranded cable core of mode, packed layer 6 is inserted in the gap of master core, and sheath 7 is extruded in the outside of packed layer 6, including
The wrapped steel belt layer 8 in the outside of sheath 7, outer jacket 9 is extruded in the outside of steel belt layer 8.
The master core includes holding wire conductor 1, signal line insulating layer 2 is extruded in the outside of wire size line conductor 1, in holding wire
The outside of insulating barrier 2 weaves signal conductor screen 3, power wire core conductor 4 is woven in the outside of signal conductor screen 3, in power
The outside of cable core conductor 4 extrudes power wire core insulating barrier 5.
The operation principle of compound power cable described in the utility model is as follows：
1st, signal core composite principle：Signal core is arranged in the middle of every power wire core, cable is so not take up empty
Between, the core number of cable core in cable conductor is reduced, reduce the external diameter of cable.
2nd, the principle of shield effectiveness is improved：
In order to signal is not influenceed by other electromagnetic interferences during ensureing signal core use, woven outside signal core
One layer signal conductor screen 3, and cable power cable core conductor 4 is coated on around signal core, there is one layer outside outermost layer
Steel belt layer 8, this three layers（Metal screen layer, power line conductor, steel belt layer）Metal material can effectively improve shield effectiveness, drop
Low shielding rejection coefficient, 0.002 can be reached using this structual shield rejection coefficient.
