Abstract
The invention belongs to the field of electric engineering of transmission lines and in particular relates to a heat-resistant transmission conductor for the transmission line. The transmission conductor comprises a steel core, a metal conductive medium layer coating the steel core, and an outer insulating layer coating the metal conductive medium layer, wherein an insulating material is filled between the steel core and the metal conductive medium layer; the metal conductive medium layer is a hollow conductor; and a tensile reinforcement through which the hollow conductor is divided into two semicircular spaces is arranged in the hollow conductor. The transmission conductor provided by the invention has the advantages that the conductor part is a heat-resistant aluminum alloy and has a function of bulking the conductor, so that the transmission conductor has high current-carrying capacity; and moreover, the conductor has a hollow shape, and the steel core is coated by the center of the conductor, so that the strength of the transmission conductor is improved, the contact surface of the conductor is large, the resistance is reduced, and the electric conductivity is high; and therefore, the transmission conductor conforms to a natural law of a skin effect of the current.
Description
Technical field
The invention belongs to transmission line electrical engineering field, relate in particular to a kind of heat-resisting transmission pressure of used for transmission line.
Background technology
Electric energy is served human society as the final energy form that the various energy are transformed, and becomes requisite production, factor in living among the human lives.Electric energy is produced by electric energy such as hydroelectric station, thermal power station, wind fields usually with producing, wants to take full advantage of electric energy and electric power must be sent to endlessly electricity needs ground.The mankind enter the information age, and are serious day by day to the dependence of electric power, singly are not that large scale industry needs a large amount of electric power, the work-at-home electric consumption on lighting, and various communication apparatus electricity consumptions, the information equipment that carries human bulk information be unable to do without electric energy too.Thereby supply of electric power need guarantee that clog-free stable transfer satisfies the human society needs.
The lead of existing employed electric line, at the center, its outside is surrounded by insulating barrier by a copper cash, and for the big lead of ampacity, and 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 cross 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.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the transmission pressure that provide a kind of ampacity height, conducts electricity very well.
To achieve these goals, the technical solution adopted in the present invention is: transmission pressure, it is characterized in that: comprise steel core, the metallic conduction dielectric layer that coats steel core, the external insulation layer of clad metal conducting medium layer, fill insulant between described steel core and metallic conduction dielectric layer, the metallic conduction dielectric layer is the conductor of hollow, is provided with the tension muscle that hollow conductor is divided into two semicircle spaces in the conductor of hollow.
Aforesaid transmission pressure, described metallic conduction dielectric layer are provided with some layers, are formed by some plain conductor concentric strandings.
Aforesaid transmission pressure, described metal are copper, aluminium, copper alloy or aluminium alloy.
Aforesaid transmission pressure, described metal are heat-resisting aluminium alloy.
Beneficial effect of the present invention: conductor part adopts heat-resisting aluminium alloy, plays the effect to the lead increase-volume, makes transmission pressure ampacity of the present invention big; Conductor is hollow form, central authorities parcels steel core, improved transmission pressure intensity, conductor contact-making surface big, reduce resistance, conductance height, make it comply with the law of nature of electric current kelvin effect.
