Abstract
The invention relates to an aluminum alloy cable for building. The aluminum alloy cable is provided with a cross linked polyethylene jacket, an inflaming retarding wrapping belt and a ceramic filler cover from outside to inside in sequence. The inner side of the ceramic filler cover is provided with an aluminum alloy cable core formed by closely arranging a plurality of aluminum alloy cable bodies with the cross section being oval, the aluminum alloy cable strips are arranged into a rectangular strip-shaped structure, and a polyurethane foam strip is formed by splicing two strip-shaped polyurethane foam bodies with the cross section being in a semi-circular arc shape. According to the aluminum alloy cable, a traditional copper conductor is replaced by an aluminum alloy conductor, the weight of the cable is obviously reduced, the pressure borne by the support for erecting a high-voltage grid in the bearing capacity range is reduced, the aluminum alloy cable can adapt to a wider range, and meanwhile the cable is wrapped by the inflaming retarding wrapping belt, the ceramic filler and the polyurethane foam strip. Compared with a traditional cable, the aluminum alloy cable can achieve the effects of being wide in application range and good in inflaming retarding performance, saving resources, prolonging service life and reducing weight.
Description
Technical field
The present invention relates to a kind of aluminium alloy cable for building.
Background technology
In known technical field, at present, the composition of cable is to be made up of cable core and the sheath that is wrapped in outside cable core, and this fireproofing of cable and shielding properties are poor, and adopting the core of copper conductor is a kind of waste of resource, not only can cause can not production-goods source loss, make production cost increase, the total weight of cable lays particular stress on, and also can be subject to metal tube and make the restriction of sheath to flexible and length, cannot be bending flexibly, can not meet client's demand.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, the aluminium alloy cable for building that a kind of stabilized structure is reliable, intensity is high, toughness is good is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of aluminium alloy cable for building, there is the crosslinked polyethylene sheath setting gradually from outside to inside, fire-retardant band and ceramic filler cover, inner side at described ceramic filler cover is provided with aluminium alloy electric cable core, described aluminium alloy electric cable core is made up of the close-packed arrays of the aluminium alloy cable of some cross section ovalizes, and described aluminium alloy cable bar is arranged in rectangular strip structure, and the rounded structure in inner side of described ceramic filler cover, in the gap forming, be equipped with polyurethane foam bar between the inner side of ceramic filler cover that is arranged in rectangular strip structure and rounded structure by aluminium alloy cable bar, the strip polyurethane foam that described polyurethane foam bar is semicircular arc by two sliver transvers sections is spliced.
Further, as a kind of concrete execution mode, the present invention is provided with irradiation crosslinking halogen-free fire retardant polyolefin layer between described ceramic filler cover and polyurethane foam bar.
Further, as a kind of concrete execution mode, the thickness of the sheath of crosslinked polyethylene described in the present invention, fire-retardant band and ceramic filler cover is followed successively by 1mm, 2mm, 1.5mm.
The invention has the beneficial effects as follows: the present invention is by replacing traditional copper conductor conductor by aluminium alloy, the weight of cable obviously alleviates, the rack bearing power of setting up High-Voltage Network has been reduced to pressure, can adapt to wider scope, simultaneously on cable, be surrounded by fire-retardant band, ceramic filler and polyurethane foam bar, can reach the effect that wide accommodation, fire resistance are good, economize on resources, increase the service life, reduce weight compared with traditional cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
In figure: 1. crosslinked polyethylene sheath, 2. fire-retardant band, 3. ceramic filler cover, 4. polyurethane foam bar, 5. aluminium alloy electric cable core, 51. aluminium alloy cable bars, 6. irradiation crosslinking halogen-free fire retardant polyolefin layer.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The preferred embodiment of the present invention's aluminium alloy cable for building as shown in Figure 1, there is the crosslinked polyethylene sheath 1 setting gradually from outside to inside, fire-retardant band 2 and ceramic filler cover 3, inner side at described ceramic filler cover 3 is provided with aluminium alloy electric cable core 5, described aluminium alloy electric cable core 5 is made up of the close-packed arrays of the aluminium alloy cable bar 51 of some cross section ovalizes, and described aluminium alloy cable bar 51 is arranged in rectangular strip structure, and the rounded structure in inner side of described ceramic filler cover 3, in the gap forming, be equipped with polyurethane foam bar 4 between the inner side of ceramic filler cover 3 that is arranged in rectangular strip structure and rounded structure by aluminium alloy cable bar 51, the strip polyurethane foam that described polyurethane foam bar 4 is semicircular arc by two sliver transvers sections is spliced.
Between described ceramic filler cover 3 and polyurethane foam bar 4, be provided with irradiation crosslinking halogen-free fire retardant polyolefin layer 6.
The thickness of described crosslinked polyethylene sheath 1, fire-retardant band 2 and ceramic filler cover 3 is followed successively by 1mm, 2mm, 1.5mm.
The present invention is by replacing traditional copper conductor conductor by aluminium alloy, the weight of cable obviously alleviates, the rack bearing power of setting up High-Voltage Network has been reduced to pressure, can adapt to wider scope, simultaneously on cable, be surrounded by fire-retardant band, ceramic filler and polyurethane foam bar, can reach the effect that wide accommodation, fire resistance are good, economize on resources, increase the service life, reduce weight compared with traditional cable.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
