Abstract
The utility model discloses a flame retardation aluminum conductor cable, comprising conductors and insulation cores. The flame retardation aluminum conductor cable is characterized in that, the outside of each aluminum conductor is extruded with a polyethylene insulating layer to form the corresponding insulation core. Two insulation cores are combined and wrapped with a low-smoke halogen-free glass fiber tape. The outside of the low-smoke halogen-free glass fiber tape is lapped with a PE tape to form a main wire core. Three main wire cores and three insulation wire cores II are combined to form a cable core. The outside of the cable core is lapped with a low-smoke halogen-free glass fiber tape II. The outside of the low-smoke halogen-free glass fiber tape is wrapped with a PE tape II. The outside of the PE tape II is wrapped with an armor formed by winding two layers of aluminium tapes. The outside of the armor is wrapped with a flame retardant layer formed by two layers of mica tapes. The outside of the flame retardant layer is provided with an oversheath made of polyethylene insulation materials. Each insulation wire core II is composed of the corresponding aluminum conductor wrapped with the polyethylene insulating layer. A central wire core is also arranged at the center of the cable. The cable provided by the utility model is simple in structure, and has the advantages of excellent performances of flame retardation, high and low temperature resistance, acid and alkali resistance, oil and water resistance, tear resistance, softness and environmental protection.
Description
Technical field
The utility model relates to one one kinds of fire-retardant aluminium conductor cables, 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-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 consists of the outer wrapped polyethylene layer of aluminium conductor; Cable center also arranges a middle core, and described middle core consists 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.
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 fire-retardant aluminium conductor cable, comprises conductor, insulated wire cores; The outer polyethylene layer 2 that extrudes of aluminium conductor 1 forms 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 by insulating material of polyethylene; Described insulated wire cores II 5 consists of the outer wrapped polyethylene layer of aluminium conductor; Cable center also arranges a middle core 11, and described middle core 11 consists 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.
