Besides, the power cable can be installed indoors or outdoors and can also be installed vertically, by a bracket or along the wall and even can be installed under the ground by a direct-buried way.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of high strength power cable.
Background technology
2004 so far, and the aluminium in China every year about 10% needs outlet, and production capacity is seriously superfluous, and meanwhile, National Development and Reform Commission's statistics: 2004 to 2006, the breach of the annual copper material of China was above 1,300,000 tons; According to the data of China Statistical Yearbook in 2008,4,520,000 tons of China's copper mine in 2007 and smart copper imports, copper and goods import volume thereof are 27,100,000,000 dollars.China copper metal market is serious dependence on import, and China causes international copper valency constantly to raise up to the inexhaustible demand of copper material, Chinese Enterprise is also gone abroad with unprecedented enthusiasm, merges external ore deposit and looks forward to, and exploits external mine, the cost of paying, that goes through is sad, and compatriots come clearly into view.From 2004 year-to-date, the copper valency has gone up above 200%u, and the copper valency is inviolent for the fluctuation of aluminium valency.Change is to the serious dependence of copper material, becomes international supply-demand relationship for a change, saves foreign exchange, takes full advantage of domestic resource, guarantees the key of power industry sustainable development.Continuous development along with urban modernization, the demand of power consumption increases year by year, the demand of power cable is increasing year by year, its copper, aluminium demand are also in continuous expansion, China is the copper ore resource scarcity, the profuse country of bauxite resource, performance and the copper of aluminium differ greatly, and the research and development alloy aluminum applies to has unique substitution of resources advantage in the power cable.
And the shortcoming of existing fine aluminium conductor power cable is mainly reflected in following several aspect: (1) bad mechanical strength fractures easily; (2) easily creep needs frequent holding screw; (3) there is potential safety hazard in overload heating easily; (4) the used terminal of fine aluminium cable is without special processing, may produce electrochemical corrosion with the junction of copper bar.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly conducts electricity very well, mechanical performance height, creep resistant are aging, high temperature resistant, the high strength power cable of long service life.
A kind of high strength power cable described in the utility model comprises cable core, and its cable core is by stranded the forming of some eradication edge cores; Gap at cable core is provided with inserts, and the outer wrapped belting layer of cable core extrudes separator, armour successively outside belting layer, and the cable outermost layer extrudes oversheath; Described insulated wire cores constitutes by aluminium alloy conductor and extruding internal shield outside the aluminium alloy conductor, insulating barrier, outer shielding layer, metal screen layer successively.
Further improve, described insulated wire cores is three.
Further improve, described armour adopts the chain sheathed structure of metal.
Further improve, described insulating barrier adopts the flame-retardant organosilane cross-linked poly-ethylene material again; Described oversheath adopts low cigarette, Halogen, flame-proof environmental protection material.
The beneficial effects of the utility model:
1, the excellent conducting performance that has of aluminium alloy conductor and excellent mechanical performance, the connection that has improved aluminium conductor is unreliable, bad mechanical strength, easy shortcoming such as creep, close with copper conductor on mechanical performance, electric property has same conductive capability by increasing section is long-pending with copper conductor, will be widely used in low-voltage distribution system;
2, the flame-retardant organosilane cross-linked poly-ethylene material is adopted in insulation, has characteristics such as low temperature resistant, high temperature resistant, anti-burning, anti-aging, low-carbon environment-friendly;
3, oversheath adopts the PVC of lead-free and cadmium-free, also can select materials such as low smoke and zero halogen, fire-retardant, refractory material, fluoroplastics, silicon rubber, fourth silicon or butyronitrile for use.Adapt to moist place and install, but also lay in the form such as direct-burried or carriage;
4, armour is nonmagnetic substance, can not produce eddy current, peels off than steel-tape armouring is lighter, easier, and it is convenient to install, and can exempt from crane span structure and install, and reduces cost; Be not limited to 360 degree and install, do not need terminal box; Flexible, reduce the requirement to pipeline, through well-designed, in installation process, can effectively avoid the lead damage;
5, Corrosion Protection is superior; When contacting with air, the rare earth aluminium alloy conductive surface forms compact oxide immediately, the various forms of corrosion of the special tolerance of this oxide layer.Environment middle rare earth corrosion resistance of aluminium alloys at seawater air salt fog and sulfur-bearing is better than copper greatly; The characteristics that rare earth aluminium alloy can bear adverse circumstances make its conductor that is widely used in the pallet inner cable, and many industrial elements and container;
6, be 40-50 useful life of the present utility model.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high strength power cable described in the utility model comprises cable core, and its cable core thoroughly does away with stranded the forming of edge core by three; Be provided with inserts 6 in the gap of cable core, the outer wrapped belting layer 7 of cable core extrudes separator 8, armour 9 successively outside belting layer 7, and the cable outermost layer extrudes the oversheath 10 that adopts low cigarette, Halogen, flame-proof environmental protection material; Described insulated wire cores is by aluminium alloy conductor 1 and be extruded in aluminium alloy conductor 1 outer internal shield 2, the insulating barrier 3 of flame-retardant organosilane cross-linked poly-ethylene material, outer shielding layer 4, metal screen layer 5 successively and constitute.
Industrial effect of the present utility model is:
By in fine aluminium, adding iron; elements such as rare earth; and through special PROCESS FOR TREATMENT; make conductor have electric property and mechanical performance preferably; the flame-retardant organosilane cross-linked poly-ethylene material is adopted in insulation; armour adopts the special chain sheathed structure of metal; sheath adopts special low cigarette; Halogen; the flame-proof environmental protection material; the ballistic properties of this cable is than copper cable low 40%; pliability is higher by 30% than copper cable; guaranteed the cable connection stability on the whole; sheathed structure is isolated from the outside cable simultaneously; even when fire; because the protective effect of outer sheathed structure greatly reduces the danger coefficient that catches fire.
The utility model provides a kind of thinking and implementation method of high strength power cable; concrete application approach is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
