Description

Communication composite power cable

Technical field

The utility model is related to a kind of cable, and especially a kind of communication composite 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.

Problems of the prior art and shortcoming are as follows：

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 one kind communication composite power cable, Power cable and signal cable are compounded in a cable, solving two kinds of cables in the prior art needs separately to lay and manufacture Problem, while also to solve existing various cable overall weight weights, bulky problem.

According to the utility model provide technical scheme, the communication composite power cable, it is characterized in that：Including power line Core and signal core, many power wire cores using side by side it is stranded by the way of be twisted into cable core, inserted in the gap location of power wire core Packed layer, extrudes sheath outside cable core, and armouring wire forms steel wire armor layer on the outside of sheath, in the steel of steel wire armor layer Some signal cores are evenly arranged between silk, oversheath is extruded on the outside of steel wire armor layer.

Further, the power wire core includes power line conductor, and power line insulating layer is extruded on the outside of power line conductor.

Further, the signal core includes holding wire conductor, and signal line insulating layer is extruded on the outside of holding wire conductor The wrapped aluminium foil layer on the outside of signal line insulating layer, the braided metal braiding layer on the outside of aluminium foil layer.

Be arranged on signal core in steel wire braid by communication composite power cable described in the utility model, realizes signal Core is combined, and reduces the external diameter of cable, reduces the weight of cable, reduces and lays number of times, reduces production and lays into This.

Brief description of the drawings

Fig. 1 is the structural representation of communication composite power cable described in the utility model.

Description of reference numerals：Power line conductor 1, power line insulating layer 2, packed layer 3, sheath 4, steel wire 5, holding wire are led Body 6, signal line insulating layer 7, aluminium foil layer 8, wire sheathing 9, oversheath 10.

Specific embodiment

With reference to specific accompanying drawing, the utility model is described in further detail.

As shown in Figure 1：Communication composite power cable described in the utility model includes power wire core and signal core, and many are moved Line of force core using side by side it is stranded by the way of be twisted into cable core, insert packed layer 3 in the gap location of power wire core, extruded outside cable core Sheath 4, steel wire armor layer is formed in 4 outside armouring wire of sheath 5, is evenly arranged between the steel wire 5 of steel wire armor layer Some signal cores, extrude oversheath 10 on the outside of steel wire armor layer.

The power wire core includes power line conductor 1, and power line insulating layer 2 is extruded in the outside of power line conductor 1.

The signal core includes holding wire conductor 6, signal line insulating layer 7 is extruded in the outside of holding wire conductor 6, in signal The wrapped aluminium foil layer 8 in the outside of line insulating layer 7, in the outside braided metal braiding layer 9 of aluminium foil layer 8.

Operation principle of the present utility model：Be disposed in parallel in signal core in steel wire armor layer by the utility model, so Cable space is not take up, the core number of cable core in cable conductor is reduced, the external diameter of cable is reduced.And outside signal core It is surrounded with one layer of aluminium foil strip, and the proof copper-wire braided layer that one layer of count is more than 80% is woven with aluminium foil strip, while copper wire Braiding layer can prevent signal core to be subject to influenceing for the electromagnetic interference that either internally or externally produces of cable, simultaneously because screen layer Shield effectiveness is protruded, and can play the shield effectiveness as steel wire armor layer, can effectively reduce cable and outside is discharged Go out electromagnetic interference.
