Description
Technical field
The utility model relates to the power cable of a kind of copper, aluminium combination.
Background technology
Existing for 0.6/1kV and the power cable more than following copper core plastic insulation three cores, its cable conductor all adopts copper conductor on the market, wherein has three to thoroughly do away with the phase conductor of edge master core as three phase mains, is used for transferring electric power to bear line voltage.For the four-core power cable, the 4th thoroughly does away with the neutral line of edge core as system, or claims zero line (N line); For 5-core power cable, the 5th thoroughly does away with the protection ground wire (PE line) of edge core as system; Fourth, fifth thoroughly does away with the edge core mainly carries three unsymmetrical currents and leakage current, plays a protective role, and this two sectional area that thoroughly does away with the edge core can equate with the sectional area of main insulation core or less than it, generally can form 4,3+1,5,4+1,4+2 cored structure.
Normally in service in practical power systems, the electric current that the neutral line and protection ground wire pass through is zero substantially, just at non-normal condition, just by electric current, and is transient current, and from system security of operation aspect, electric power system is quite safe.From real system operation aspect, system is less demanding to the neutral line, that is to say that the neutral line and protective earthing line all use copper conductor, considers its manufacturing cost height from manufacturing firm; From utilization of resources aspect, country advocate to use with aluminium for copper, and all uses copper material, also is a kind of waste to resource; Consider that from economic aspect this kind core all adopts the power cable price of copper product more expensive, the cost performance of cable is also lower; Consider that from the cable laying operation aspect power cable weight of full copper material is big, high to the facility requirement of construction, construction is inconvenient, and efficient is low.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of and both can satisfy the operation power requirement, can reduce production costs again, the copper that convenient construction uses, the power cable of aluminium combination.
The technical scheme that solution the utility model technical problem is adopted is the power cable of this copper, aluminium combination, comprise main line, the neutral line formed by copper conductor, the main line and the neutral line are surrounded by insulating barrier outward respectively, conductor in the neutral line is an aluminium conductor, and the main line and the neutral line outwards have strapping successively, extrude oversheath.The protection ground wire is arranged in this power cable, and the conductor in the protection ground wire is an aluminium conductor.
Conductor in the neutral line in the utility model and the protection ground wire for copper, can be saved the metal copper material with aluminium greatly, has improved the copper material resource utilization, and the cable construction at transportation of cable simultaneously and scene is all greatly convenient.
Description of drawings
Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment 1
Fig. 2 is the structural representation of the utility model embodiment 2
Among the figure: 1,2,6-conductor, 3-insulating barrier, 4-bundling belt 5-extrude oversheath 7-filler 8-neutral line 9-protection ground wire 10-main line
Embodiment
Embodiment 1: as shown in Figure 1, the utility model is the four-core power cable in the present embodiment, promptly comprise main line 10, the neutral line 8 formed by copper conductor, main line 10 and the neutral line 8 outer insulating barriers 3 that are surrounded by respectively, the main line 10 and the neutral line 8 outwards have strapping 4 successively, extrude oversheath 5, and the conductor 2 in the neutral line 8 is an aluminium conductor.Wherein conductor 1, conductor 2 can be circle, fan-shaped or other structure, adopt sector structure in the present embodiment.The cross-sectional sizes of conductor 1, conductor 2 is to require to determine according to electric power system, determines to wrap in the thickness of the insulating barrier 3 outside the neutral line 8 then according to the voltage of electric power system.
In process of production, to extrude or the lapped insulation material on conductor 1, the conductor 2 earlier, form insulating barrier 3 respectively, then with main line 10, the neutral line 8 strandings, outer wrapped binding strap 4 behind the stranding, according to the environment for use requirement of cable, strapping 4 and extrude between the oversheath 5 and can extrude inner cushion layer and armour, adopt non-sheathed structure in the present embodiment, load onto at outermost layer at last and extrude oversheath 5.
Embodiment 2: as shown in Figure 2; the utility model is a 5-core power cable in the present embodiment; promptly except the neutral line 8 is arranged; and the conductor in the neutral line 2 is outside the aluminium conductor; protect ground wire 9 in this power cable in addition; the conductor 6 of protection in the ground wire 9 also adopts aluminium conductor, and the conductor 1 in three main lines adopts copper conductor.Conductor 2 equates with the sectional area of conductor 6, but littler than the sectional area of conductor 1.There is filler 7 to be positioned at outside main line 10, the neutral line 8 and the protection ground wire 9, and in the inside of strapping 4, to increase roundness of the present utility model.The cross-sectional sizes of conductor 1, conductor 2, conductor 6 is to require to determine according to electric power system, determines the thickness of insulating barrier 3 then according to the voltage of electric power system.Conductor 1, conductor 2, conductor 6 can be circle, fan-shaped or other structure, adopt circular configuration in the present embodiment.
The utility model is when production process; to extrude or the lapped insulation material on conductor 1, conductor 2, the conductor 6 earlier; form insulating barrier 3 respectively; with main line 10, zero line 8 and protection ground wire 9 strandings, insert packing material 7 during stranding then, outer then wrapped binding strap 4; environment for use requirement according to cable; strapping 4 and extrude between the oversheath 5 and can extrude inner cushion layer and armour adopts non-sheathed structure in the present embodiment, load onto at outermost layer at last and extrude oversheath 5.
This four-core or 5-core power cable generally can form 4,3+1,5,4+1,4+2 cored structure, or are with core formula 5-core power cable.
Advantage of the present utility model and good effect are: the utility model produce with the neutral conductor of cross section aluminium or When the conductor 2 of protection ground wire, conductor 6, than the neutral conductor of original copper material or the conductor in the protection ground wire, its material The material cost can reduce more than 80%, and its weight has reduced more than 70%, and current-carrying capacity has then only reduced 23%, joint Make an appointment with a large amount of copper products, reduced production costs, improved the resource utilization of copper product, and the valency of cable Lattice have also reduced many. Cable both can satisfy service requirement, had saved simultaneously a large amount of metal materials, greatly Improve the cost performance of cable, had good economic benefit and social benefit. Simultaneously, because the weight of cable Alleviated, the transportation of cable and on-site cable construction are all greatly convenient.
