Abstract
The invention discloses a kind of steel-tape armouring pvc sheath cold resistant cables, it includes oversheath, steel-tape armouring layer, inner sheath, gasket for packing, crosslinked polyetylene insulated layer and conductor, it is characterised in that：The conductor is twisted by several insulated copper-cores；It is extruded with crosslinked polyetylene insulated layer outside the conductor；It is extruded with inner sheath outside the crosslinked polyetylene insulated layer；It is provided with gasket for packing between the crosslinked polyetylene insulated layer and inner sheath；It is extruded with steel-tape armouring layer outside the inner sheath；It is extruded with oversheath outside the steel-tape armouring layer.The increased steel-tape armouring layer of the present invention can increase the mechanical strength of cable, improve erosion prevention, and any of which laying may be used, be more suitable for the directly buried installation of Rock Region.Crosslinked polyetylene insulated layer can guarantee that the when of being bent at a temperature of 20 DEG C does not crack；Oversheath is all made of cold-resistant polrvinyl chloride protective cover material in cable, has ensured and has been installed safely in 20 DEG C of temperature ranges.
Description
Technical field
The present invention relates to field of cables more particularly to a kind of steel-tape armouring pvc sheath cold resistant cables.
Background technology
Wires and cables industry is the second largest industry for being only second to automobile industry in China, and the electric wire gross output value has been more than beautiful
State becomes the first big electric wire producing country in the world.
Set point of temperature when most of electric wire product mounting and installation is generally all not less than 0 DEG C, needs pair when being less than 0 DEG C
Cable body is heated, and ensures that cable body temperature is not less than 0 DEG C, to prevent in mounting and installation due to insulating and protecting
Cover material is hardened and brittle cracking occurs, causes installation accident.Chinese Regional is wide, the especially western and northern territory period in winter
It is long, and the laying of cable requires to be not less than 0 DEG C, can not carry out after on the one hand causing electric wire installing engineering in winter, influences
Apply project progress；Another aspect electric wire is packed with the compound disk of hophornbeam, and shape is huge, compares electric cable heating
Difficulty, without the heating tool specially come, misoperation damages cable quality.
Invention content
In order to overcome the defect of the above-mentioned prior art, the object of the present invention is to provide a kind of steel-tape armouring pvc sheaths
Cold resistant cable.
The present invention takes following technical scheme to realize：A kind of steel-tape armouring pvc sheath cold resistant cable, it
Including oversheath, steel-tape armouring layer, inner sheath, gasket for packing, crosslinked polyetylene insulated layer and conductor, the conductor is by several eradications
Edge copper core is twisted；It is extruded with crosslinked polyetylene insulated layer outside the conductor；It is extruded with outside the crosslinked polyetylene insulated layer
Inner sheath；It is provided with gasket for packing between the crosslinked polyetylene insulated layer and inner sheath；It is extruded with steel-tape armouring outside the inner sheath
Layer；It is extruded with oversheath outside the steel-tape armouring layer.
A kind of above-mentioned steel-tape armouring pvc sheath cold resistant cable, the inner sheath and oversheath are cold-resistant polychlorostyrene
Ethylene protective cover material is made, and is to extrude structure.
A kind of above-mentioned steel-tape armouring pvc sheath cold resistant cable, the steel-tape armouring layer use clad steel band knot
Structure.
In summary the invention has the advantages that：The machinery that increased steel-tape armouring layer can increase cable is strong
Degree improves erosion prevention, and any of which laying may be used, be more suitable for the directly buried installation of Rock Region.Crosslinking is poly-
Ethylene insulating layer can guarantee that the when of being bent at a temperature of -20 DEG C does not crack；Oversheath is all made of cold-resistant polrvinyl chloride shield in cable
Jacking is ensured and is installed safely in -20 DEG C of temperature ranges.
Description of the drawings
Fig. 1 is cross-sectional structure schematic diagram of the present invention；
Wherein：1, conductor；2, crosslinked polyetylene insulated layer；3, gasket for packing；4, inner sheath；5, steel-tape armouring layer；6, oversheath.
Specific implementation mode
The present invention is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute to the present invention's
Any restrictions.
As shown in Figure 1, a kind of steel-tape armouring pvc sheath cold resistant cable, it be by oversheath 6, steel-tape armouring layer 5,
Inner sheath 4, gasket for packing 3, crosslinked polyetylene insulated layer 2 and conductor 1, the conductor 1 are twisted by several insulated copper-cores；Institute
It states and is extruded with crosslinked polyetylene insulated layer 2 outside conductor 1；4 are provided with gasket for packing between the crosslinked polyetylene insulated layer 2 and inner sheath
3；It is extruded with inner sheath 4 outside the crosslinked polyetylene insulated layer 2；It is extruded with steel-tape armouring layer 5 outside the inner sheath 4；The steel
It is extruded with oversheath 6 outside band armor 5.
The inner sheath 4 and oversheath 6 is made of cold resistance polyvinyl chloride protective cover material, is to extrude structure.Ensure -20 DEG C
It is installed safely in temperature range.
The steel-tape armouring layer 5 uses clad steel band structure, enhances the mechanical performances such as tensile strength, compression strength,
Protection prolongs the service life, and is also prevented from mouse and baits.
The above is the embodiment of the present invention, therefore all structure, feature and principle institutes according to described in the present patent application range
The equivalent change or modification done is included in present patent application model.
