Abstract
The utility model discloses a naked uniline used in an electric wire conductor, which comprises a conductor with an exposed outer layer, wherein the conductor is arranged to a penetrating hollow structure. The utility model further discloses a naked stranded wire used in the electric wire conductor, which comprises a multilayer twisting conductor, wherein the conductor adopts the penetrating hollow structure. The naked uniline and the naked stranded wire not only has the function of transmitting electrical energy, but also has the function of hole enlargement, and the cooling fluid can be filled in the hollow passage when transmitting electrical energy, so as to lower the heating temperature.
Description
Technical field
The utility model discloses electric wire and cable conductor with the naked single line of enlarged diameter type and naked twisted wire, particularly a kind of ampacity is convenient to a kind of electric wire and cable conductor of cooling off greatly, simultaneously with naked single line and naked twisted wire.
Background technology
Cable conductor is solid with pole stock and naked single line, naked twisted wire or bare conductor goods in the prior art.On the one hand, after the cable conductor energising, conductor can generate heat, the size of current-carrying capacity of cable depends on also that generally the conductor heating also increased thereupon when the degree, especially the cable load current that generate heat with conductor were big, therefore when cable needs bigger load, just need the increase cross-sectional area of conductor.
On the other hand, cable conductor can produce kelvin effect, under the kelvin effect effect, effective area of passage of cable conductor inside reduces, AC impedance significantly strengthens, and its caloric value is also very big, especially large-section lead, the conductor of internal layer does not often have electric current to pass through, therefore be benchmark generally, take to enlarge the wire diameter technology, guaranteeing under the desired wire diameter prerequisite of corona with the conventional wires specification that meets the specification, save conductor material, reduce the aluminium cross section of lead.
A kind of strand formula expanded conductor of taking out is arranged in the prior art, take out between strand single line of hole enlargement layer and be difficult to be completely fixed, the cooperation that adds construction tool coincide inadequately, so structural instability, because traction and continuous mistake pulley can make outer single line jump out somewhere, and make lead be difficult to be accepted in when construction by superhigh pressure or extra-high voltage electric transmission and transformation line project.And another kind of interior tubular type expanded conductor or other forms of expanded conductor, owing to need to increase the hole enlargement strutting piece of steel or other materials, weight that this has also increased lead undoubtedly, and increased raw-material use amount, improved the cost in production and the intermediate links.
Summary of the invention
Goal of the invention: technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of electric wire and cable conductor with naked single line and naked twisted wire.
Technical scheme: the utility model discloses the naked single line of a kind of electric wire and cable conductor, comprise outer exposed conductor, described conductor is set to the hollow-core construction that the center connects.
The invention also discloses the naked twisted wire of a kind of electric wire and cable conductor, include the stranded conductor of multilayer, described conductor is the hollow-core construction that the center connects.
The stranded conductor of multilayer described in the utility model be two-layer more than.
In the naked twisted wire described in the utility model, preferably, the diameter of described center conductor constitutes a kind of stranded conductor based on center conductor thus greater than the diameter of outer contact.
Beneficial effect: both as electric energy transmitting, itself has the hole enlargement effect again to a kind of electric wire and cable conductor described in the utility model, can feed cooling fluid when electric energy transmitting in hollow passageway with naked single line and naked twisted wire, reduces heating.Simultaneously, the internal diameter size of this hollow-core construction can be regulated according to the diameter of lead itself and the difference of field of employment, greatly reduces raw-material use amount, has reduced cost of material, has also reduced cost of transportation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done further to specify, above-mentioned and/or otherwise advantage of the present utility model will become apparent.
Fig. 1 is a naked single line cross section structure schematic diagram in the utility model.
Fig. 2 is a naked twisted wire cross section structure schematic diagram in the utility model.
Embodiment:
Embodiment 1
As shown in Figure 1, the utility model discloses the naked single line of a kind of electric wire and cable conductor, comprise outer exposed conductor 1, described conductor 1 is set to the hollow-core construction 2 that the center connects.
Embodiment 2
As shown in Figure 2, the invention also discloses the naked twisted wire of a kind of electric wire and cable conductor, comprise center conductor 3, at the outer closely stranded two-layer outer contact 4 that has of center conductor 3, described center conductor 3 and outer contact 4 are set to the hollow-core construction 5 that the center connects.The diameter of center conductor described in the present embodiment 3 is greater than the diameter of outer contact 4.
The utility model provides thinking and the method for a kind of electric wire and cable conductor with naked single line and naked twisted wire; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a 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 improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each part not clear and definite in the present embodiment is realized.
