Abstract
The utility model discloses an electric wire and cable and aims at providing an electric wire and cable which can enhance the electric conductivity and increase the transmission power without increasing cross-sectional area. The utility model is provided with an electric conduction metal core which takes a shape of ellipse and an insulating layer; the utility model is mainly used for transmission of electric power.
Description
Technical field
The utility model relates to a kind of electric wire.
Background technology
At present, electric wire is used for the transmission of electric power, and its conductive metal core all is round, being made at outer surface wrap insulate layer, in order to increase through-put power, generally is the cross section that increases cable, promptly add thick cable to improve conductive capability, reduce the loss of electric energy on the circuit.But, adding thick cable the consumption of the non-ferrous metal of making lead is increased greatly, and the weight of cable is significantly increased, this will install to setting up of cable and bring difficulty and the cost of investment of transmission system is obviously improved.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, utilizes " kelvin effect " theory in the metallic conduction to provide a kind of cross-sectional area that do not increase just can improve electric conductivity, increases the electric wire of through-put power.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: round conductive metal core of the prior art is made into oval-shaped, the insulating barrier of its outer surface also is oval accordingly.
Because under the situation that does not increase cross-sectional area, ovally can increase the circulation that be convenient to electric current than the external surface area of circle, therefore adopt the utility model can improve electric conductivity, increase through-put power not increasing under the transmission system condition of cost.
Description of drawings
Accompanying drawing is a cross section view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing shows structure of the present utility model, and conductive metal core 2 is oval-shaped, and the insulating barrier 1 of outer wrapping also accordingly is oval.Under the constant prerequisite of cross-sectional area, oval-shaped electric wire is bigger than circular electric wire exterior surface area, is better than circular electric wire according to the electric conductivity of the electric wire of " kelvin effect " elliptical shape.
The utility model also can be with the electric wire of above-mentioned sub-thread (root), the twisted wire cable that tangles mutually and be made into multiply.
Claims (1)
1. electric wire, it has insulating barrier (1) and conductive metal core (2), it is characterized in that: conductive metal core (2) and insulating barrier (1) are ellipticalnesses.
