The flame-retardant aluminum conductor cable comprises conductors and insulating wire cores, and is characterized in that a PE insulating layer is wrapped on each conductor in an extruding mode to form one insulating wire core; a low-smoke zero-halogen glass fiber belt is wrapped on every two corresponding insulating wire cores in a lapping mode after the two insulating wire cores are combined together, and PE belts are wrapped on the low-smoke zero-halogen glass fiber belts in a lapping mode to form main wire cores; the three wire cores are combined with three insulating wire cores II to form a cable core; a low-smoke zero-halogen glass fiber belt II is wrapped on the cable core in a lapping mode, a PE belt II is wrapped on the low-smoke zero-halogen glass fiber belt II in a lapping mode, an armor layer formed by winding two layers of aluminum tapes is wrapped on the PE belt II in a lapping mode, a double-layer mica tape fireproof layer is wrapped on the armor layer in a lapping mode, and an outer sheath made of PE insulating materials is arranged outside the fireproof layer; each insulating wire core II is formed by wrapping a PE insulating layer on an aluminum conductor in a lapping mode; a middle wire core is arranged in the center of the cable. The flame-retardant aluminum conductor cable is simple in structure and has good flame retardance, high temperature and low temperature resistance, acid-base resistance, oily water resistance, tearing resistance, flexibility and environment friendliness.
Description
Technical field
The present invention relates to one one kinds of fire-retardant aluminium conductor cables, belong 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, but 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 exceedes 9500 dollars.Along with the pressure that this year, national currency expanded increases suddenly, 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 transport and installation process, has also brought the effect of energy-conserving and environment-protective for client.See with existing market situation, become again inevitable choice with " aluminium " for copper.Simultaneously at society, the generation of fire incident more and more takes place frequently, this just requires cable to have good fire resistance, particularly also require cable in the time having breaking out of fire can ensure normal operation a period of time in the concentrated place of some personnel, the personnel of guarantee have enough time escape, and when 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.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide a kind of both economy, have the fire-resistant aluminium conductor cable with environmental protection fire resistance.
The solution of the present invention is as follows: a kind of fire-retardant aluminium conductor cable, comprises conductor, insulated wire cores; Aluminium conductor extrudes polyethylene layer outward and forms insulated wire cores; Wrapped low smoke and zero halogen glass fibre belt after two insulated wire cores combinations, the outer wrapped PE band of described low smoke and zero halogen glass fibre belt forms master core; Three master cores and three insulated wire cores II constitute cable core; The outer wrapped low smoke and zero halogen glass fibre belt II of described cable core, wrapped PE band II outside low smoke and zero halogen glass fibre belt, PE with II outside the armour of wrapped double-deck aluminium strip coiling, wrapped double-deck mica tape fireprotection layer outside armour, the outer oversheath of being made by insulating material of polyethylene that arranges of described fireprotection layer; Described insulated wire cores II is made up of the outer wrapped polyethylene layer of aluminium conductor; Cable center also arranges a middle core, and described middle core is made up of the outer wrapped low smoke and zero halogen glass fibre belt of three insulated wire cores, PE band.
Further, described armour is formed by the double-deck aluminium strip coiling of 0.5mm thickness.
Conductor of the present invention adopts aluminium core conductor, insulating barrier adopts crosslinked polyethylene to make, this material not only has the superior electrical property of polyethylene, and compared 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, avoid cable in use to occur the phenomenon of insulation cracking, greatly improve the useful life of cable.When product of the present invention 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 place that some personnel relatively concentrate.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of fire-retardant aluminium conductor cable, comprises conductor, insulated wire cores; Outside aluminium conductor 1, extrude polyethylene layer 2 and form insulated wire cores; Wrapped low smoke and zero halogen glass fibre belt 3 after two insulated wire cores combinations, the outer wrapped PE of described low smoke and zero halogen glass fibre belt 3 is with 4 formation master cores; Three master cores and three insulated wire cores II 5 constitute cable core; The outer wrapped low smoke and zero halogen glass fibre belt II 6 of described cable core, in the outer wrapped PE band II 7 of low smoke and zero halogen glass fibre belt 6, armour 8 at PE with the outer wrapped double-deck aluminium strip coiling of II 7, at the outer wrapped double-deck mica tape fireprotection layer 9 of armour 8, the oversheath 10 that the described outer setting of fireprotection layer 9 is made up of insulating material of polyethylene; Described insulated wire cores II 5 is made up of the outer wrapped polyethylene layer of aluminium conductor; Cable center also arranges a middle core 11, and described middle core 11 is made up of the outer wrapped low smoke and zero halogen glass fibre belt of three insulated wire cores, PE band.Described armour 8 is formed by the double-deck aluminium strip coiling of 0.5mm thickness.
