Abstract
The utility model discloses an electric power wire, which comprises a steel core, a conductor and an outer insulation protective layer. An inner insulation layer is wrapped outside the steel core, the cross section of the conductor is shamrock-shaped, the conductor is hollow, and the inner insulation layer is sleeved in the conductor. The outer insulation protective layer is wrapped on the outer surface of the shamrock-shaped conductor. The electric power wire has the advantages that the steel core with high tensile strength is arranged in the electric power wire to enable the wire to have high tensile strength, the center of the conductor is hollow, the length of the outer surface is lengthened, contact face is large, resistance is reduced, conductivity is strong, conductive performance is good, the natural law of current collected on skin is satisfied, and the electric power wire is light in weight.
Description
Technical field
The utility model relates to a kind of electrical lead of transmission line.
Background technology
At present, the employed lead of prior art is generally circle, all is that a steel wire is at the center; Insulating barrier is full of in its outside; And for the big lead of flow, conductor is to be combined by the coil buckling of multiply copper cash and increase the flow of electric current, and its shortcoming is to bring into play the flow in maximum unit cross section; Because all being easy outer surface from conductor, electric current flows through; The central part flow is very little, and the structure of this kind lead has not only increased resistance has also wasted a large amount of conductor materials, does not meet the law of nature of electric current collection skin.
The utility model content
To the weak point that prior art exists, the utility model is in a kind of in light weight, material saving, a kind of electrical lead that conduction is good are provided.
To achieve these goals, the technical scheme of the utility model is: a kind of electrical lead, comprise steel core, conductor and external insulation protective layer, and described steel core covers the bag inner insulating layer outward; Described cross-sectional area of conductor is shaped as the clover shape, in be empty tube shape, inner insulation layer is inserted in the conductor; Described external insulation protective layer covers on the outer surface that wraps in clover shape conductor.
The beneficial effect of the utility model is: be provided with a high-tensile steel core in the electrical lead of this utility model, make lead have better tensile strength, the conductor central part is hollow state; The outer surface perimeter length increases; Wire weight is light, and resistance reduces, and conduction power is strong; Conduct electricity very well, meet the law of nature of electric current collection skin.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with concrete embodiment the utility model is done explanation further.
As shown in Figure 1, the electrical lead of the utility model comprises steel core 1, conductor 3 and external insulation protective layer 4, the described steel core 1 outer bag inner insulating layer 2 that covers; Described conductor 3 cross sectional shapes are the clover shape, in be empty tube shape, inner insulation layer 2 is inserted in the conductor 3; Described external insulation protective layer 4 covers on the outer surface that wraps in clover shape conductor 3; Be provided with a high-tensile steel core in the electrical lead of this utility model; Make lead have better tensile strength, lead is made the clover shape, and cross section does not increase; But the outer perimeter of lead increases, and makes it to meet the law of nature of electric current collection skin.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection range of the utility model.
Claims (1)
1. an electrical lead comprises steel core, conductor and external insulation protective layer, and it is characterized in that: described steel core covers the bag inner insulating layer outward; Described cross-sectional area of conductor is the clover shape, in be empty tube shape, inner insulation layer is inserted in the conductor; Described external insulation protective layer covers on the outer surface that wraps in clover shape conductor.
