Description

A kind of bus cable
Technical field
The utility model relates to a kind of power equipment, is a kind of bus cable specifically.
Background technology
Traditional bus cable adopts the Combination Design of conductor, insulating barrier and sheath usually, due to the temperatures as high 70 ° of bus cable long-time running, and during short circuit, the maximum temperature of conductor is even up to 160 °, traditional bus cable due to structure simple, insulating barrier simplicity of design, cannot bear so high temperature usually, is easy to generation security incident on fire.
The shield effectiveness of bus cable traditional is in addition also poor, owing to only arranging insulating barrier, when bearing larger current, is easy to puncture insulating barrier, and intensity is also inadequate, cannot produce larger angle of bend.
Utility model content
Utility model object: in order to overcome the deficiencies in the prior art, the bus cable that the utility model provides a kind of anti-shielding, high temperature resistance and gains in strength.
For achieving the above object, the technical solution adopted in the utility model is a kind of bus cable, and innermost layer is stranded copper conductor; And each stranded copper conductor is all enclosed with insulating barrier outward, and be filled with packed layer outside a pair insulating barrier, and packed layer passes through the first lapping layer of outer cladding by its wrapped stranding; Described first lapping layer is also coated with internal shield, outer shielding layer, inner sheath, armour, the second lapping layer and oversheath outward successively.
Wherein, to be that some anaerobic single round copper wire are stranded form described copper conductor.
Wherein, described anaerobic single round copper wire is provided with 7 altogether.
Wherein, described insulating barrier is three-layer co-extrusion physic foaming insulating barrier, is endodermis, foaming layer and exodermis from inside to outside successively.
Wherein, the material of described packed layer is non-hygroscopic inserts.
Wherein, the material of described internal shield is aluminium-plastic tape.
Wherein, described outer shielding layer is the mesh shields layer of tinned wird synnema braiding.
Wherein, described inner sheath and oversheath are PVC sheath.
Wherein, described armour is the armour that zinc-plated circular mild steel wire is entwined.
Beneficial effect: copper conductor of the present utility model forms by 7 oxygen-free copper single lines are stranded, its electric conductivity is more outstanding, and three-layer co-extrusion physic foaming insulating barrier is set, the high temperature that when can bear short circuit, cable produces, and the utility model arranges the double layer screen layer of different materials, shield effectiveness is better, the armour that the zinc-plated circular mild steel wire that the utility model is arranged in addition is entwined can not only increase the intensity of whole cable, can also ensureing that conductor is when bearing larger current load, insulating not breakdown.
Accompanying drawing explanation
Fig. 1 is the utility model structural section figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of bus cable, innermost layer is stranded copper conductor 1; And be all enclosed with insulating barrier 2 outside each stranded copper conductor 1, and be filled with packed layer 3 outside a pair insulating barrier 2, and packed layer 3 passes through the first lapping layer 4 of outer cladding by its wrapped stranding; Described first lapping layer 4 is outer is also coated with internal shield 5, outer shielding layer 6, inner sheath 7, armour 8, second lapping layer 9 and oversheath 10 successively.
Concrete, copper conductor 1 forms for some anaerobic single round copper wire are stranded; Copper conductor of the present utility model adopts 7 diameters to be that the anaerobic single round copper wire of 0.4mm is stranded and forms, and its composition, performance and outward appearance meet the regulation in GB/T3956; And copper conductor 1 any surface finish, burr, sharp edge etc. without greasy dirt, not damaged shielding and insulation, without single line that is protruding or fracture.
Concrete, insulating barrier 2 is three-layer co-extrusion physic foaming insulating barrier, is endodermis, foaming layer and exodermis from inside to outside successively; This physical blowing is specially physical blowing polyethylene, to be closely extruded on copper conductor 1 and easily to peel off; And insulating barrier 2 thickness is 0.6mm, two insulating barriers 2 are respectively orange and blue, and insulating barrier 2 thickness average value is not less than the nominal value of regulation.
On the cross section of insulating barrier 2, the thickness of the thinnest point of any point is not less than the 90%-0.1mm of nominal thickness; Core shift degree must not be greater than 15%.
By in the process of two insulating barrier 2 pair twists, the insulated wire cores dextrad of orange and blue two different colours twists together, twisting pitch length≤90mm.
Concrete, the material of packed layer 3 is non-hygroscopic inserts; Non-hygroscopic inserts can make the tight gapless of the cable core after pair twist, makes external diameter rounding.
Concrete, the material of internal shield 5 is aluminium-plastic tape.
Concrete, the mesh shields layer that outer shielding layer 6 weaves for tinned wird synnema.
Internal layer shielding 5 is Aluminium plastic composite strip, Duplication >=15%, and metal covering connects with outer shielding layer 6, and the network structure that outer shielding 6 is the braiding of tinned wird synnema, count is 90%.
Concrete, inner sheath 7 and oversheath 10 are PVC sheath.
Inner sheath 7 adopts fire-retardant orange colour PVC sheath material to extrude, and extrudes that jacket surface is bright and clean, rounding; Sheath nominal thickness meets standard regulation, and any point minimum thickness is not less than the 85%-0.1mm of nominal value; Oversheath 10 any surface finish, its cross section is without phenomenons such as macroscopic sand holes, impurity and bubbles, and color is orange.
Concrete, armour 8 is the armour that zinc-plated circular mild steel wire is entwined; And steel wire diameter is 0.9mm.
Adopt technique scheme, copper conductor of the present utility model forms by 7 oxygen-free copper single lines are stranded, and its electric conductivity is more outstanding.
And three-layer co-extrusion physic foaming insulating barrier is set, the high temperature that when can bear short circuit, cable produces, and the utility model arranges the double layer screen layer of different materials, shield effectiveness is better, the armour that the zinc-plated circular mild steel wire that the utility model is arranged in addition is entwined can not only increase the intensity of whole cable, can also ensureing that conductor is when bearing larger current load, insulating not breakdown.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
