Abstract
The utility model relates to a kind of flexible aluminium alloy fireproof cable, set gradually conductor, refractory insulating layer, filling, lapping layer, watertight composition, chain armour from inside to outside, wherein, conductor adopts 8000 series alloys meeting ASTM B800-2005 standard, its conductor resistance meets GB/T3956-2007 standard, conductor adopts circle to press, and double-deck Mica tape insulation, core stranding is stranded.Watertight composition adopts and extrudes LSOH anti-flaming cross-linked polyolefin, and chain armour adopts stainless steel band.The utility model structure fire cable, adopts aluminium alloy conductor and the chain armouring sheath of stainless steel band, light unit weight.Adopt the insulation of aluminium alloy conductor, wrapped mica tape, have cost low, production efficiency is high.Adopt stainless steel band chain armouring, cable can be made when random length in the middle of non junction.Adopt the chain sheathed structure of stainless steel band, the bending radius of cable is little, can reach 7 times of the outside diameter of cable.
Description
Technical field
The utility model relates to a kind of flexible aluminium alloy fireproof cable, belongs to field of cable technology.
Background technology
The development of economic society, facilitates the development in city.Urban architecture along with the development in city, constantly to maximization, High Level and densification future development.And the personnel's highly dense in building, fire hazard constantly increases.Former common cable does not have fire-proof function, and fire-fighting fireproof cable generally adopts copper conductor structure in copper pipe sheath.The restriction (copper pipe is for being generally 6m/ root) being subject to copper pipe length of this structure, erection joint is many, and joint hidden danger is large.Cable Unit Weight weight, is unfavorable for large length vertical run.Meanwhile, all adopt copper conductor, copper pipe sheath, inorganic oxide magnesium to insulate, manufacturing cost is high, is unfavorable for extensive use.
Utility model content
The purpose of this utility model is to provide a kind of flexible aluminium alloy fireproof cable, to provide a kind of fireproof cable with flexibility of low cost.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of flexible aluminium alloy fireproof cable, set gradually conductor, refractory insulating layer, filling, lapping layer, watertight composition, chain armour from inside to outside, wherein, conductor adopts 8000 series alloys meeting ASTM B800-2005 standard, its conductor resistance meets GB/T 3956-2007 standard, conductor adopts circle to press, and double-deck Mica tape insulation, core stranding is stranded.Watertight composition adopts and extrudes LSOH anti-flaming cross-linked polyolefin, and chain armour adopts stainless steel band.
The beneficial effect of this utility model is: the utility model adopts 8000 series alloys meeting ASTM B800-2005 standard as cable conductor, employing Mica tape insulate, extrude low smoke, zero halogen cross-linked polyolefin watertight composition, the chain armouring sheath of stainless steel band.This structure fire cable, adopts aluminium alloy conductor and the chain armouring sheath of stainless steel band, light unit weight.Adopt the insulation of aluminium alloy conductor, wrapped mica tape, have cost low, production efficiency is high.Adopt stainless steel band chain armouring, cable can be made when random length in the middle of non junction.Adopt the chain sheathed structure of stainless steel band, the bending radius of cable is little, can reach 7 times of the outside diameter of cable.
Accompanying drawing explanation
Fig. 1 is multi-core cable structure figure structure schematic representation in the utility model embodiment.
Description of symbols in figure: 1, conductor; 2, refractory insulating layer; 3, inserts; 4, lapping layer; 5, watertight composition; 6, chain armour.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, better to understand the utility model.
A kind of flexible aluminium alloy fireproof cable, set gradually conductor 1, refractory insulating layer 2, inserts 3, lapping layer 4, watertight composition 5, chain armour 6 from inside to outside, wherein, conductor 1 adopts 8000 series alloys meeting ASTM B800-2005 standard, its conductor resistance meets GB/T 3956-2007 standard, conductor 1 adopts circle to press, and double-deck Mica tape insulation, core stranding is stranded.Watertight composition 5 adopts and extrudes LSOH anti-flaming cross-linked polyolefin, and chain armour 6 adopts stainless steel band.
Multicore cable as shown in Figure 1, adopts Equations of The Second Kind aluminium alloy conductor, strandedly presses circle, and pressing coefficient, to be not less than 0.9. double-layer and double-side mica tape overlap wrapped, and the rate of putting up is not less than 50%.After wrapped, twisted synthesizing cable, fill mineral wool rope, wrapped double-deck glass fibre belt, the rate of putting up is not less than 20%.Extrude LSOH anti-flaming cross-linked polyolefin watertight composition outside cable core, the oxygen index of low-smoke halogen-free polyolefin is no less than 36, and thickness is not less than 1.8mm.The outer chain armouring of stainless steel band adopting thickness to be not less than 0.65mm of watertight composition 5, armouring non junction.
The above is 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 are also considered as protection range of the present utility model.
