Abstract
The utility model relates to an electric power conducting wire, which has a steel core; the outside of the steel core is compound with insulating plastic; a conductive body for supplying power is sheathed on the insulating plastic. The conductive body is in sleeve barrel shape; the periphery of the conductive body is coated with an outer insulating protective layer. The utility model has low cost, and is capable of largely saving the material of the conductive body in the utility model, wherein, the central part of which is in hollow form, and has large current contact face and strong conductive capability. The electric power conducting wire is made to conform to the natural law of the current skin effect.
Description
The utility model relates to a kind of electrical lead of electric line.
Existing employed lead, all be by a copper cash at the center, its outside is surrounded by insulating barrier, and for the big lead of ampacity, conductor is to be combined and increased the flow of electric current by the coil buckling of multiply copper cash.The shortcoming of this lead is: the flow that can not bring into play maximum unit section, because all being easy outer surface from conductor, electric current flows through, the central part flow is very little, the structure of this kind lead has not only strengthened resistance and has also wasted a large amount of conductor materials, and does not meet the law of nature of electric current kelvin effect.
The purpose of this utility model provides a kind of in light weight, material saving, contact-making surface is big, conduction is good a kind of electrical lead.
The utility model is achieved in that a kind of electrical lead; comprise steel core, conductor and external insulation protective layer; it is characterized in that: steel core is compounded with ambroin outward; described conductor is sleeve-like; and ambroin is inserted in conductor, described external insulation protective layer is coated on the outer surface of conductor.
The utility model can replace the employed all kinds of different leads of existing electric line; electrical lead of the present utility model is to be provided with a steel core that improves tensile strength at the center of lead; this steel core can be according to the size of conductor cross-section, can form by one or more strands of steel wires are stranded; the outer fusion of described steel core or cementation one deck ambroin; be with a conductor that is used to power on ambroin, conductor is covered with the external insulation protective layer outward.
The utility model compared with prior art has following advantage: cost is low, can save the conductor material significantly.Therefore, contact-making surface is big, reduce resistance, conduction power is strong, makes it comply with the law of nature of electric current kelvin effect because what the conductor in the utility model adopted is that central part is the hollow form body.In addition, because alleviating of wire weight when transmission pressure is installed, alleviated the weight of putting the lead shaft tower, also alleviated labour intensity simultaneously.
Drawing is described as follows:
Fig. 1 is the utility model cross section sectional structure schematic diagram.
Below in conjunction with accompanying drawing the utility model is done further narration.
Fig. 1 is the utility model cross section cross-sectional schematic.As can be seen from the figure; central part of the present utility model has the tensile strength that a steel core 4 is used to improve lead; the steel core 4 outer ambroins 3 that are compounded with; cover is useful on the conductor 2 of power supply usefulness on ambroin 3; this conductor 2 is cylindric, and it can adopt copper or aluminum according to different needs, also can change the wall thickness on the cylinder according to the consumption of electric current; the periphery of the inner hole wall of described conductor 2 and ambroin 3 adopts tight fit, is coated with insulating protective layer 1 on the periphery of described conductor 2.
Claims (1)
1, a kind of electrical lead; comprise steel core (4), conductor (2) and external insulation protective layer (1); it is characterized in that: the outer ambroin (3) that is compounded with of steel core (4); described conductor (2) is sleeve-like; and ambroin (3) is inserted in conductor (2), described external insulation protective layer (1) is coated on the outer surface of conductor (2).
