Abstract
The invention relates to a square cable, which comprises a protection layer and a plurality of conducting wires, wherein the conducting wires are arranged in the protection layer and are mutually twisted, an enamelling layer is coated outside each conducting wire, the cross section of the conducting wire is in a rectangular shape, and the conducting wires are twisted for forming a cable with the rectangular cross section. Compared with the prior art, the square cable has the advantages that the transmission efficiency is high, the cost is low and the like.
Description
Technical field
The present invention relates to a kind of square cable, especially relate to a kind of square cable that is used for the distribution equipment winding.
Background technology
When conductor dbus was crossed alternating current, because the kelvin effect of electric charge, electric current was along the outer surface transmission of every conductor.Traditional cable adopts circular design basically, and when area was identical, circular girth was the shortest.Along with country in the development in fields such as wind energy, optical energy power and country greatly develops clean energy resource and energy-saving and cost-reducing policy makes society require increasingly high to the energy transformation ratio of transformer, inverter etc.; Like this, traditional round cable more and more can not satisfy the requirement of industry development.Not only efficiency of transmission is low for it, and quality, volume are bigger, uses also very inconvenient.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence the square cable that a kind of efficiency of transmission is high, cost is low to be provided.
The object of the invention can be realized through following technical scheme:
A kind of square cable comprises that protective layer and many are located in the protective layer and stranded lead each other, and every lead is coated with the enamel-cover layer outward, and the cross section of described lead is square, and the stranded formation cross section of all leads is foursquare cable.
The length of side of described lead is less than or equal to 0.1mm.
Described lead is provided with at least 4.
Described lead is the copper lead.
The thickness of described enamel-cover layer is less than or equal to 0.003mm.
Compared with prior art, the present invention adopts squared design, and under the identical situation of sectional area, its transmission table area is more than 1.13 times of round cable, has improved efficiency of transmission, and can practice thrift a lot of materials, helps reducing the quality and the volume of cable.
Description of drawings
Fig. 1 is the cross section structure sketch map of the embodiment of the invention 1;
Fig. 2 is the perspective view of the embodiment of the invention 2.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
As shown in Figure 1, a kind of square cable comprises that protective layer 1 and 484 are located in the protective layer 1 and stranded lead 3 each other, the every lead 3 outer thick enamel-cover layers 2 of 0.003mm that are coated with.Lead 3 is superfine copper lead, and its cross section is the square of length of side 0.1mm, and all leads 3 are foursquare cable with the stranded formation cross section of 22 * 22 mode.
Because adopt the design of square structure, under the identical situation of sectional area, its transmission table area is more than 1.13 times of round cable, has improved efficiency of transmission, and can practice thrift a lot of materials, helps reducing the quality and the volume of cable.
As shown in Figure 2, the lead in a kind of square cable, this cable is provided with 25, and stranded with 5 * 5 mode, remainder is all identical with embodiment 1.
Claims (6)
1. square cable comprises that protective layer and many are located in the protective layer and stranded lead each other, and every lead is coated with the enamel-cover layer outward, it is characterized in that, the cross section of described lead is rectangular, the cable that the stranded formation cross section of all leads is a rectangle.
2. a kind of square cable according to claim 1 is characterized in that, the cross section of described lead is square, and the stranded formation cross section of all leads is foursquare cable.
3. a kind of square cable according to claim 2 is characterized in that the length of side of described lead is less than or equal to 0.1mm.
4. a kind of square cable according to claim 1 is characterized in that described lead is provided with at least 4.
5. a kind of square cable according to claim 1 is characterized in that, described lead is the copper lead.
6. a kind of square cable according to claim 1 is characterized in that the thickness of described enamel-cover layer is less than or equal to 0.003mm.
