Abstract
The utility model discloses an outdoor mobile high-voltage flexible cable with properties of cold resistance, tear resistance and tension resistance. The outdoor mobile high-voltage flexible cable comprises a plurality of conductors. Each conductor is formed by intertwisting a plurality of brass wires to be a cluster. After the brass wires are clustered, a conductor shielding layer, a first insulating layer, an insulation shielding layer, a separating layer wound by a polyester band, and a metal shielding layer are respectively wrapped outside each conductor. An inner winding layer formed by non-woven fabrics (gapped winding) is wrapped outside each metal shielding layer. A filling rope is disposed inside among the plurality of conductors wrapped with the inner winding layers. The filling rope is a tension-resistant steel wire wrapped by a second insulating layer. The plurality of conductors wrapped with the inner winding layers are mutually intertwisted to be a cable, the filling rope serving as a center. After cabling, an outer winding layer formed by intersecting and braiding flaxen threads is wound outside the cable. A sheath layer is plastic-extruded outside the outer winding layer. The sheath material of the sheath layer is extrusion-molded to enter the meshes of the outer winding layer and the inner winding layers so that an integral body is formed. The cable of the utility model exhibits super-high twist-resistance and tension-resistance, and enables the service life to be prolonged.
Description
Technical field:
The utility model relates to the field and uses the high voltage power cable field, relates in particular to a kind of cold-resistant anti-open-air mobile high-voltage flexible cable of using of mill tension that tears.
Background technology:
Along with society constantly advances; The user requires also increasingly high to cable performance, the field is required too with high voltage power cable, and it also is increasingly high requiring; Because open-air environment is comparatively abominable; Generally at subzero four or five ten degree, also having is exactly that open-air moving with high-voltage flexible cable requires that good mobility is arranged such as the winter temperature in the north, so this cable must have cold-resistant, anti-characteristics such as mill, tension of tearing.
The utility model content:
The purpose of the utility model provides a kind of cold-resistant anti-open-air mobile high-voltage flexible cable of using of mill tension that tears; Can move in the open air and use high-voltage flexible cable; Anti-superpower cold resistance and the good anti-mill property of tearing are arranged; Because unique isolation and tension technology, this cable has anti-functions peculiar and the tension function reversed of open-air removal cable, has solved other removal cables (open-air removal cable need have the superpower anti-function of reversing) short problem in useful life.
The utility model technical scheme following:
The cold-resistant anti-open-air mobile high-voltage flexible cable of using of mill tension that tears; Comprise many conductors; Many conductors adopt the stranded bunchy of several copper wires respectively; Many conductors are enclosed with conductor shield, first insulating barrier, insulation screen, the separator of the wrapped formation of polyester belt, metal screen layer outward respectively successively behind the bunchy; It is characterized in that: metal screen layer is wrapped with the interior lapping layer that nonwoven fabrics (gapped formula is wrapped) constitutes, and several conductors inboard of lapping layer is provided with gasket for packing in being enclosed with, and gasket for packing is the tension steel wire of parcel second insulating barrier; Several conductors of lapping layer are the mutual stranded stranding in center with the gasket for packing in the parcel; The outside is surrounded with the outer lapping layer that the linen thread interlacing reticulates formation behind the stranding, and the outer extrusion moulding of outer lapping layer has restrictive coating, becomes integral body in the mesh of the protective cover material of restrictive coating lapping layer, interior lapping layer outside extrusion molding gets into.
Describedly cold-resistant anti-ly tear open-air the moving of mill tension and use high-voltage flexible cable, it is characterized in that: described several cross-sectional area of conductor are generally 10～240mm
2, several copper wires form for the annealing oxygen-free copper bar draws.
Describedly cold-resistant anti-ly tear open-air the moving of mill tension and use high-voltage flexible cable, it is characterized in that: described first, second insulating barrier and restrictive coating material all adopt tension to tear silicon rubber.
Material that the utility model adopts is:
(1) conductor: conductor material is that oxygen-free copper bar draws the lead that forms.Conductor should adopt the 5th kind of annealed copper conductor or the tin-coated copper conductor of stipulating among the GB/T3956, the outer wrapped conductor shield of conductor.Cross-sectional area of conductor is generally 10～240mm
2
(2) insulation: according to abominable environment for use and the lower serviceability temperature of cable; Select the anti-tear side of drawing high pressure silicon rubber as insulating material, because insulating requirements has certain mechanical property and electrical property preferably, common silastic material mechanical property is relatively poor; Especially tear resistance is poor; Can not satisfy the normal mounting operation of cable,, select for use tension to tear high pressure silicon rubber insulation material and can satisfy serviceability through test, checking.Silastic material has good pliability; Make the minimum operating temperature of cable reach-50～-60 ℃ Celsius; Improve the high voltage withstanding characteristic of product simultaneously; Also have very high thermal endurance, excellent cold resistance, excellent electric insulation performance, good aging properties, excellent oil resistance, and nontoxic odorless.
(3) the outer lapped insulation screen of insulated wire cores, braiding copper mesh screen, spend lapping layer in the wrapped nonwoven fabrics.
(4) stranding and cable core are wrapped: the cable insulation core should twist together (it is stranded jointly that tensile structure is placed on the centre of cable core), and the outermost layer direction of lay is a dextrad, and tie up for the linen thread intersection in its outside.
(5) sheath: sheath adopts tension to tear silastic material.Jacket surface should be smooth, rounding, color and luster basically identical, and section should not have visible bubble of eyesight and impurity.
The utility model has the advantages that:
The utility model simple in structure, easily manufactured laid easily; Cable has superpower cold resistance and the good anti-mill property of tearing, because unique isolation and tension technology, this cable has superpower anti-function and the tension function turned round of open-air removal cable, has prolonged the useful life of cable effectively.
