Description
Technical field
The utility model belongs to the aerial field of cable technology of power conveying, and in particular to pressure drag water in a kind of single weather resistant
Aerial insulated cable.
Background technology
At present, known middle pressure single aerial insulated cable is common aerial cable, and Conductor-conductor shielding-XLPE is exhausted
Edge, XLPE insulating barriers use the weather-proof organosilane crosslinked polyethylene of black.The process kind of this cable is being manufactured, is being had in Insulation Material various
Additive, content of carbon black is small, and weatherability is general, and water preventing ability is general, and the degree of cross linking of crosslinked with silicane and degree of purity have impact on absolutely
The various performances of edge.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose that pressure drag water is aerial exhausted in a kind of single weather resistant
Edge cable.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
Press water blocking overhead insulated cable in a kind of single weather resistant, pressure drag water overhead insulating electricity in described single weather resistant
Cable has the cable core conductor positioned at center；Described cable core conductor is twisted shaping by multiple conductor monofilament together with water blocking yarn；Institute
State and waterstop is coated with the outside of cable core conductor；Conductor shield is coated with the outside of the waterstop；The conductor shield
Outside be provided with double insulating layer；Described double insulating layer includes true qualities processes for chemically crosslinked polyethylene inner insulating layer and black weather resistant
External insulation layer.
The utility model proposes a kind of multicore in press weather-proofing aerial insulation cable, metallic conductor space is filled with blocking water
Yarn, wrapped waterstop on the outside of conductor, play certain resistance effect；Inner insulating layer uses dry cross-linking, and the degree of cross linking is high, uniformity
It is good；Not added in insulation influences the additive of its performance, ensures insulating properties;There is the external insulation of weatherability on the outside of inner insulating layer
Layer, insulating properties can add, weatherability increase；In weather Special section, external insulation layer can protect inner insulating layer continuously to work, not by
Interference；In a word, the weather-proofing aerial insulation cable has that simple in construction, safe to use, water preventing ability is high, and insulating properties is high, weatherability
Height, stability is high, the performance of service life length.
Brief description of the drawings
Fig. 1 is the schematic cross-section of the utility model weather-proofing aerial insulation cable.
In figure：1st, conductor monofilament, 2, water blocking yarn, 3, waterstop, 4, conductor shield, 5, in true qualities processes for chemically crosslinked polyethylene
Insulating barrier, 6, black weather resistant external insulation layer.
Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following instance is hereby enumerated, and is coordinated attached
Figure describes in detail as follows：
As shown in figure 1, water blocking overhead insulated cable is pressed in a kind of single weather resistant, pressure drag water in described single weather resistant
Aerial insulated cable has the cable core conductor positioned at center；Described cable core conductor is by multiple conductor monofilament 1 together with water blocking yarn 2
Twisted shaping；Waterstop 3 is coated with the outside of the cable core conductor；The outside of the waterstop 3 is coated with conductor shield 4；
Double insulating layer is provided with the outside of the conductor shield；Described double insulating layer includes true qualities processes for chemically crosslinked polyethylene interior insulation
Layer 5 and black weather resistant external insulation layer 6；True qualities crosslinked polyethylene inner insulating layer can use the processes for chemically crosslinked polyethylene of true qualities
（XLPE）, improve the various performances of insulating barrier；Black weather resistant external insulation layer can use the weather-proof polyethylene of any black
（PE）Or crosslinked polyethylene（XLPE）Insulation, content of carbon black >=2.5%, improve the weather resistance of external insulation layer.
