Abstract
The utility model discloses a shape of a saddle is packing for cable, the main part cable, including sheath, thread core and auxiliary core, the sheath parcel is outside at thread core and auxiliary core, still includes the packing, and the packing cross section is for being the shape of a saddle, fixed set up thread core and auxiliary core the institute inside the centralize clearance, the packing includes central tensile piece and the cladding packing macromolecular material outside the tensile piece. The rubber of this kind of special saddle shape cover packing flexible cable the for can prop up and prop up thread core and auxiliary core, the stranding outside and the sheath process sinle silk to stand the effect of extrusion force indeformable. Not only improve the cable section outward appearance, packed in addition and more step up the reality, strengthened shocking resistance and extrusion performance of cable.
Description
Technical field:
This utility model relates to cable industry, particularly relates to a kind of shape of a saddle filling strip of power cable.
Background technology:
The production of rubber sleeve flexible cable is in China's history the most for many years, the most many cable producers this mobility of all production and operation is strong, the cable of superior performance, occupying critically important position in cable kind, it has become numerous enterprises and has obtained the popular product of good economic benefit.
Just because of it is popular product, in order to obtain good economic benefit, reduce cost, improve quality and become the target that we pursue.Rubber sleeve flexible cable typically can take core gap to fill, and the purpose of filling is: (1) keeps stranding rounding, so that the outside diameter of cable rounding after extrusion sheath and smooth surface；(2) make stranding core structure stable；(3) expensive sheath rubber can be saved with the packing material of low cost；(4) center bedding core (many insulated wire cores twisted synthesizing cables) also acts as mechanical damping effect, strengthens shock resistance and the extrusion performance of cable.
Packing is mainly had fan-shaped packing and circular packing by Shape Classification.Fan-shaped packing is mainly used in big external diameter circle master core edge voids, and fan-shaped packing interior angle designs according to void shape, and outer arc designs according to stranding external arc, so using fan-shaped packing stranding surface roundness preferable.Circular packing is mainly used to fill center, and strand insulated wire cores is played a supporting role.
And for the cable of 3+3 structure (auxiliary core is positioned at master core gap for 3 master cores, 3 auxiliary cores), when the maximum core external diameter that auxiliary core external diameter can be filled more than master core gap, center-filled position utilizes conventional circular packing, and in stranding and oversheath operation, core can be squeezed the effect of power, core can be caused to deform, on the one hand, cross-section of cable appearance poor, on the other hand, the thickness of insulating layer being extruded can be thinning, and the electrical property sending a telegraph cable is the most up to standard.
Utility model content:
In order to solve the problems referred to above, this utility model provides the rubber sleeve flexible cable packing of a kind of special horse-saddle, can support master core and auxiliary core, and the effect standing extruding force at stranding and oversheath operation core is indeformable.Not only improve cross-section of cable outward appearance, and fill more consolidation, enhance the shock resistance of cable and the technical scheme of extrusion performance:
A kind of shape of a saddle filling strip of power cable, main body cable, including sheath, master core and auxiliary core, sheath is wrapped in outside master core and auxiliary core, also include packing, packing cross section is in the shape of a saddle, is fixedly installed on inside master core and the formed center clearance of auxiliary core, and packing includes central tensile part and the filled high polymer material being coated on outside tensile members.
As preferably, recess A and interior recess B in packing outer surface, interior recess A surface diameter and master core equal diameters, interior recess B surface diameter and auxiliary core equal diameters.
As preferably, central tensile part is high tensile strength fibrous material or steel wire rope.
As preferably, filled high polymer material is rubber composition or thermoplastic elastomer (TPE).
The beneficial effects of the utility model are:
This utility model provides the rubber sleeve flexible cable packing of a kind of special horse-saddle, can support master core and auxiliary core, and the effect standing extruding force at stranding and oversheath operation core is indeformable.Not only improve cross-section of cable outward appearance, and fill more consolidation, enhance shock resistance and the extrusion performance of cable.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, this utility model devises a kind of shape of a saddle filling strip of power cable, main body cable, including sheath 1, master core 2 and auxiliary core 3, sheath 1 is wrapped in master core 2 and auxiliary core 3 is outside, also includes that packing 4, packing 4 cross section are in the shape of a saddle, being fixedly installed on inside master core 2 and the formed center clearance of auxiliary core 3, packing 4 includes central tensile part 4a and the filled high polymer material 4b being coated on outside tensile members 4a.And recess A4c and interior recess B4d in packing 4 outer surface, interior recess A4c surface diameter and master core 2 equal diameters, interior recess B4d surface diameter and auxiliary core 3 equal diameters.
Central tensile part 4a therein is high tensile strength fibrous material or steel wire rope, and filled high polymer material 4b is rubber composition or thermoplastic elastomer (TPE).
This utility model provides the rubber sleeve flexible cable packing 4 of a kind of special horse-saddle, can support master core 2 and auxiliary core 3, and the effect standing extruding force at stranding and oversheath operation core is indeformable.Not only improve cross-section of cable outward appearance, and fill more consolidation, enhance shock resistance and the extrusion performance of cable.
Above-described embodiment is preferred embodiment of the present utility model; it it is not the restriction to technical solutions of the utility model; as long as the technical scheme that can realize on the basis of above-described embodiment without creative work, in the range of being regarded as falling into the rights protection of this utility model patent.
