Abstract
The utility model provides a single-core power cable, particularly relates to a non-metallic armored single-core power cable which has excellent electric property, physical property, chemical stability and certain compression strength and needs to bear certain pressure and metal penetration attachment. The outmost layer of the cable is a sheath, a non-metallic armored layer is arranged inside the sheath, a lapping layer is arranged inside the non-metallic armored layer, an insulation layer is arranged inside the lapping layer, and a conductor is arranged inside the insulation layer. The non-metallic armored single-core power cable is a composite armored layer combined by a foaming polyethylene buffer layer and a polyvinylidene fluoride (PVDF) layer. The non-metallic armored single-core power cable is reasonable and simple in structure, easy in production and manufacturing, low in cost and fine in using property.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of non-metallic sheath single-core power cables.
Background technology
The power cable that is called as " artery " of society is made huge contribution for human modernization, its good electric property, physical property, chemical stability, and therefore, this cable has obtained using widely.Power cable is used for the transmission of electric power system electric energy mostly, as power plant, conveying circuit, transformer station, electric equipment etc., because of environment and requirements of one's work, the part power cable need bear certain pressure, because equipment interface requires to pass the steel hole and equipment interface need to require the minor diameter power cable in some occasion.Power cable to this environmental requirement adopted steel-tape armouring single-core power cables or the non-armoured power cable of single core more in the past.But two kinds of cables damage cable or waste electric energy because being in of magnetic loss makes cable wear the heating of metal aperture place.
Summary of the invention
The purpose of this utility model is exactly that a kind of single-core power cables with good electric property, physical property, chemical stability will be provided, also having must compression strength, is fit to the needs bearing certain pressure and wears the non-metallic sheath single-core power cables that metal is set up.
The purpose of this utility model is achieved in that a kind of non-metallic sheath single-core power cables, and the outermost layer of this cable is to be provided with in sheath, the sheath to be provided with in non-metallic armoring layer, the non-metallic armoring layer to be provided with in insulating barrier, the insulating barrier in lapping layer, the lapping layer to be provided with conductor.
Described non-metallic armoring layer is the composite armor that polyethylene foamed resilient coating and Kynoar (PVDF) layer combine, and the conductor in the compound armouring, insulating barrier, screen constitute the cable electrical part,
Described conductor is 1 class, the 2 class conductors that meet the GB/T3956-1997 requirement or is to meet 5 classes, the 6 class conductors that GB/T3956-1997 requires.
The material of described insulating barrier is to meet XLPE or the PVC material of stipulating among the GB/T12706-2002.
Beneficial effect: the utility model is rational in infrastructure simple, manufactures easily, and cost is low, and serviceability is good.Conductor adopts and to meet the GB/T3956-1997 material, and cable is that rigid structure adopts 1 class or 2 class conductors, when cable such as soft junction structure with 5 classes or 6 class conductors.Insulation meets the XLPE that stipulates among the GB/T12706-2002 or the requirement of PVC material.The protection sheath adopts polyvinyl chloride or low smoke and zero halogen material, and performance meets the regulation of GB/T12706-2002 and relevant criterion.Can be directly buried during this cable laying, especially suitable to needs cabling in metal aperture, can avoid cable being generated heat or the loss electric energy because metal armouring produces magnetic loss.
Description of drawings
Accompanying drawing is a non-metallic sheath single-core power cables structural representation;
Among the figure: 1 conductor, 2 insulating barriers, 3 lapping layers, 4 polyvinylidene fluoride layer, 5 polyethylene foamed resilient coatings, 6 sheaths.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings: a kind of non-metallic sheath single-core power cables: conductor 1 adopts and meets the GB/T3956-1997 material, and cable is that rigid structure adopts 1 class or 2 class conductors, when cable such as soft junction structure with 5 classes or 6 class conductors.Outside conductor, extrude and meet XLPE or the PVC insulating barrier 2 formation insulated wire cores of stipulating among the GB/T12706-2002., wrapped lapping layer 3 outside insulating barrier 2.Outside lapping layer 3, extrude polyvinylidene fluoride layer 4, outside polyvinylidene fluoride layer 4, extrude polyethylene foamed resilient coating 5, extrude protection sheath 6, constitute the non-metallic sheath single-core power cables at outermost layer.
