Abstract
The utility model discloses a fireproof aluminum conductor cable. A cable core is formed by the intertwisting of more than two insulating wire cores. Each insulating wire core consists of an aluminum conductor (1), a mica-tape fireproof layer (2), and an insulating layer (3) from the inside to the outside. The exterior of the cable core is wrapped by a low-smoke zero-halogen glass fiber tape (4) which is wrapped by a PE (polyethylene) tape (5). The exterior of the PE tape (5) is wrapped by a steel tape armoring layer (6) which is wrapped by an external sheath (7). The cable provided by the utility model is simple in structure, is good in flame retardation, is resistant to high and low temperature, is resistant to acid and base, is resistant to oil and water, is resistant to tearing, is soft, and has the performance of environmental protection.
Description
Technical field
The utility model relates to a kind of fire-resistant aluminium conductor cable, belongs to electric wire field.
Background technology
Recent years; particularly, since 2005, the copper metal price ascensional range of international market was very large, since 2005; copper goes up and falls 9000 beautiful yuan/ton from 2000 beautiful yuan/ton; the economic crisis of 2008, makes again copper valency fall and gets back to 3000 beautiful yuan/ton, yet 2009; copper valency goes up and falls 8000 beautiful yuan/ton from 3000 beautiful yuan/ton again; to in by the end of December, 2011, World Copper valency records high again, and copper valency per ton is over 9500 dollars.Along with this year, the pressure of national currency expansion increases suddenly, and copper valency also has strong up-trend, and copper product shared cost in copper cable reaches more than 70%, and the price of copper cable is also being risen at the sound, thereby causes user's input cost significantly to increase.In the face of continuous soaring copper valency, and unpredictalbe upward price trend, many clients start to select cheap aluminium cable.Because aluminium is very high at natural content, the price of aluminum current material is equivalent to 1/3rd left and right of copper.Not only aspect raw material supply, there is advantage, at manufacture view, the cable of a same length, the weight ratio copper of required aluminium also lighter, generally can light 30-50%, therefore, in whole transportation and installation process, also for client, has brought the effect of energy-conserving and environment-protective.With existing market situation, see, with " aluminium ", for copper, become again inevitable choice.Simultaneously at society, the generation of fire incident more and more takes place frequently, this just requires cable to have good fire resistance, particularly in the concentrated place of some personnel, also require cable when having breaking out of fire can guarantee normal operation a period of time, the personnel of assurance have enough time escape, and during burning, produce less smog and harmful substance, avoid causing the generation of human casualty accident and property loss, require cable to have good fire resistance.
Utility model content
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of both economy, has the fire-resistant aluminium conductor cable with environmental protection fire resistance.
Scheme of the present utility model is as follows: a kind of fire-resistant aluminium conductor cable, it is characterized in that being twisted into cable core by two bursts of above insulated wire cores, described insulated wire cores from-inner-to-outer consists of aluminium conductor (1), mica tape flame retardant coating (2) and insulating barrier (3), wrapped low smoke and zero halogen glass fibre belt (4) outside cable core, wrapped PE band (5) outside low smoke and zero halogen glass fibre belt (4), wrapped steel-tape armouring layer (6) outside PE band (5), wrapped oversheath (7) outside steel-tape armouring layer (6).
Described insulated wire cores is three strands.
Described insulating barrier (3) consists of polyethylene insulation material.
The utility model conductor adopts aluminium core conductor, insulating barrier adopts crosslinked polyethylene to make, this material not only has the superior electrical property of polyethylene, and compare with common polythene, its mechanical performance is improved greatly, especially tensile strength is common polythene several times, the environmental stress resistance performance of this material also improves a lot in addition, common polythene material environmental stress resistance Performance Ratio is poor, in use easily there is insulation cracking phenomenon, but the environmental stress resistance performance of this new material is very significantly improved, avoided cable in use to occur the phenomenon of insulation cracking, greatly improved the useful life of cable.When the utility model product has burning, smoke density is low, and non-corrosiveness gas is overflowed, and does not also produce harmful hydracid material, possesses the advantages such as fire resistance simultaneously, can be widely used in the more concentrated place of some personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of fire-resistant aluminium conductor cable, a kind of fire-resistant aluminium conductor cable, it is characterized in that being twisted into cable core by two bursts of above insulated wire cores, described insulated wire cores from-inner-to-outer consists of aluminium conductor 1, mica tape flame retardant coating 2 and insulating barrier 3, wrapped low smoke and zero halogen glass fibre belt 4 outside cable core, at low smoke and zero halogen glass fibre belt 4, outer wrapped PE is with 5, at PE, is with 5 outer wrapped steel-tape armouring layers 6, at the outer wrapped oversheath 7 of steel-tape armouring layer 6.
Described insulated wire cores is three strands.
Described insulating barrier 3 consists of polyethylene insulation material.
Conductor 1 adopts aluminium core conductor, Mica tape forms mica tape flame retardant coating 2, first at the overlapping wrapped two-layer mica tape of conductive surface, all adopt overlapping wrapped, the rate of putting up is controlled between 20 ~ 30%, insulating barrier 3 adopts cross-linked polyethylene insulating material, its production process has been produced at SJ65 plastic extruding machine, adopt tubular molding tool to extrude, then carry out commissure, guarantee that cable has good electrical property, high mechanical performance and stronger tensile strength, low smoke and zero halogen glass fibre belt 4 guarantees the roundness of cable, inner covering 5 adopts PE band, 6 adopt galvanized steel strip armouring, outer jacket 7 adopts low-smoke non-halogen flame-retardant outer jacket, also adopt tubular molding tool to extrude.Production equipment can adopt different sheathing machines to produce according to the size of the outside diameter of cable: the use SJ90 extruder of external diameter below 35mm, the use SJ120 extruder of external diameter more than 35mm.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
