Abstract
The invention discloses a wire with a reduced conductor sectional area. The wire with the reduced conductor sectional area comprises a conductor and an insulting layer which wraps the conductor. The insulting layer is a crosslinked polythene insulting layer or a crosslinked polypropylene insulting layer or an ethylene propylene diene monomer rubber insulting layer or a silicone rubber insulting layer or a polytetrafluorethylene insulting layer or a crosslinked polythene-polypropylene copolymer insulting layer, the sectional area of the conductor is slightly smaller than a sectional area of a conductor of a polyvinyl chloride wire with the same square number. Compared with the polyvinyl chloride wire with the same square number of the existing technology, the wire with the reduced conductor sectional area is lightly smaller in sectional area and capable of saving the conductor material cost of the wire.
Description
Technical field
The present invention relates to a kind of electric wire, relate in particular to a kind of long-pending electric wire of cross-sectional area of conductor that reduces.
Background technology
At present, general electric wire is polyvinyl chloride (PVC) electric wire, and polyvinyl chloride (PVC) electric wire comprises the insulating barrier of conductor and this conductor of coating, and the material of this insulating barrier is polyvinyl chloride.
Yet, above-mentioned polyvinyl chloride (PVC) electric wire is because insulating barrier is polyvinyl chloride, the polyvinyl chloride heatproof is low, this causes the ampacity of polyvinyl chloride (PVC) electric wire lower, load capacity a little less than, so in order to improve ampacity and load capacity, when selecting BLV, generally need to select the large electric wire of sectional area (square number), the electric wire ampacity that sectional area (square number) is large is large, load capacity is strong, but caloric value is little, can satisfy the heatproof requirement of polyvinyl chloride (PVC) electric wire, because copper material is more expensive, this has increased buying and use cost.
Summary of the invention
Thereby the object of the present invention is to provide a kind of long-pending electric wire that reduces material cost of cross-sectional area of conductor that reduces.
For achieving the above object, the long-pending electric wire of cross-sectional area of conductor that reduces provided by the present invention, the insulating barrier that comprises conductor and this conductor of coating, it is characterized in that: insulating barrier is crosslinked polyetylene insulated layer, crosslinked polypropylene insulating barrier, ethylene propylene diene rubber insulating barrier, silicone rubber insulation layer, teflon insulation layer or crosslinked fluorinated ethylene propylene copolymer insulating barrier, and the long-pending cross-sectional area of conductor that is slightly less than the polyvinyl chloride (PVC) electric wire of identical square number of described cross-sectional area of conductor amasss.
As mentioned above, the insulating barrier that the present invention reduces the long-pending electric wire of cross-sectional area of conductor is crosslinked polyetylene insulated layer, crosslinked polypropylene insulating barrier, ethylene propylene diene rubber insulating barrier, silicone rubber insulation layer, teflon insulation layer or crosslinked fluorinated ethylene propylene copolymer insulating barrier, the long-pending cross-sectional area of conductor that is slightly less than the polyvinyl chloride (PVC) electric wire of identical square number of cross-sectional area of conductor amasss, compare with the polyvinyl chloride (PVC) electric wire of the identical square number of prior art, cross-sectional area of conductor is long-pending smaller, and this has reduced the conductor material cost.
Description of drawings
Fig. 1 is the structural representation that invention reduces the long-pending electric wire of cross-sectional area of conductor.
Reduce the long-pending electric wire 10 of cross-sectional area of conductor, conductor 11, insulating barrier 12, cross-sectional area of conductor amasss S.
Embodiment
By describing technology contents of the present invention in detail, being realized purpose and effect, be explained in detail below in conjunction with execution mode.
The present invention reduces the insulating barrier 12 that the long-pending electric wire 10 of cross-sectional area of conductor comprises conductor 11 and coats this conductor 11, insulating barrier 12 is crosslinked polyetylene insulated layer, crosslinked polypropylene insulating barrier, ethylene propylene diene rubber insulating barrier, silicone rubber insulation layer, teflon insulation layer or crosslinked fluorinated ethylene propylene copolymer insulating barrier, and the long-pending cross-sectional area of conductor that is slightly less than the polyvinyl chloride (PVC) electric wire of identical square number of cross-sectional area of conductor amasss.
Now illustrate:
In the situation that ampacity is all 20A, the heatproof of 4 squares of polyvinyl chloride (PVC) electric wire is 70 ℃, and adopts the long-pending S of cross-sectional area of conductor of the electric wire of crosslinked polyetylene insulated layer can be 3.6-3.9mm
2, minimum heatproof reaches 105 ℃.
And adopt the electric wire of crosslinked polypropylene insulating barrier, silicone rubber insulation layer, teflon insulation layer or crosslinked fluorinated ethylene propylene copolymer insulating barrier also similar with upper example, repeat no more.
The present invention reduces the long-pending electric wire 10 of cross-sectional area of conductor and compares with the polyvinyl chloride (PVC) electric wire of prior art, long-pending S is smaller for cross-sectional area of conductor, although this can cause conductor 11 caloric values to become a little large, but because insulating barrier 12 is crosslinked polyetylene insulated layer, crosslinked polypropylene insulating barrier, ethylene propylene diene rubber insulating barrier, silicone rubber insulation layer, teflon insulation layer or crosslinked fluorinated ethylene propylene copolymer insulating barrier, heat resistance is excellent, can load amass the smaller caloric value that increases of S because of cross-sectional area of conductor.
In sum, the insulating barrier 12 that the present invention reduces the long-pending electric wire 10 of cross-sectional area of conductor is crosslinked polyetylene insulated layer, crosslinked polypropylene insulating barrier, ethylene propylene diene rubber insulating barrier, silicone rubber insulation layer, teflon insulation layer or crosslinked fluorinated ethylene propylene copolymer insulating barrier, the cross-sectional area of conductor that the long-pending S of cross-sectional area of conductor is slightly less than the polyvinyl chloride (PVC) electric wire of identical square number amasss, compare with the polyvinyl chloride (PVC) electric wire of the identical ampacity of identical square number of prior art, cross-sectional area of conductor is long-pending smaller, and this has reduced the conductor material cost.
The present invention is not limited to above-mentioned embodiment, and those skilled in the art that also can make multiple variation accordingly, but any and the present invention are equal to or similar variation all should be encompassed in the scope of claim of the present invention.
