Abstract
The utility model discloses a power cable conductor which is intertwisted into being by a plurality of conductive single wires. The utility model is characterized in that a semi-conductive layer or an insulation layer is covered on the outer surface of each conductive single wire. As the utility model adopts a structure that a semi-conductive layer or an insulation layer is arranged on the outer surface of each conductive single wire, for large section cable conductors transporting relatively heavy AC, traditional regular intertwisting ways can be utilized to process the conductive wire core, skin effect can be eliminated as well. Besides, the expense on special equipment is saved.
Description
Technical field
The utility model relates to a kind of industry, domestic mains cable conductor, specifically relates to a kind of power cable conductor.
Background technology
At present, the effect of power cable conductor wire core is a transmission current, and the transmission capacity of cable is mainly by the cross-sectional sizes and the structures shape of conductor.The cable conduction core is generally by the metal material with high specific conductance---and copper or aluminium conductor single line are made.But for flexibility or the curvature that increases cable, the conductor wire core of larger cross-section is by many stranded the forming of conductor single line than minor diameter.Power cable owing to kelvin effect, can reduce the effective rate of utilization of cross-sectional area of conductor when the transmission AC great current, so GB GB/T3956-1997 " conductor of cable " regulation, and the cross section is at 95mm
2And above cable conductor can be made up of 5 and following partial cross-section conductor, keeps apart with semi-conductive layer or insulating barrier between each part of conductor.Because the moulding of milliken conductor needs special-purpose process equipment, and the expense of this equipment is higher, generally reaches up to ten million units, so manufacturer generally all still adopts traditional conductor structure.But some cable standard mandatory provision will be adopted the milliken conductor structure, as GB12706.3-91 " rated voltage 35kV and following copper core, aluminium core power cable with cross-linked polyethylene insulation " regulation, nominal cross 1000mm
2And above copper core should adopt the milliken conductor structure, and GB11017-89 " rated voltage 110kV copper core, aluminium core power cable with cross-linked polyethylene insulation " regulation cross section is 1000,1200mm
2Copper conductor should adopt the milliken conductor structure.The special equipment that does not have milliken conductor machine-shaping like this, the production range of many enterprise products just has been subjected to considerable restraint.
The utility model content
The purpose of this utility model just is to provide a kind of and adopts traditional regular stranded mode to process conductor wire core, and can eliminate kelvin effect, saves the power cable conductor of special equipment expense.
The purpose of this utility model can realize by following measure:
The utility model is by many stranded the forming of conductor single line, is evenly equipped with semi-conductive layer or insulating barrier at each conductor single line outer surface.
Semi-conductive layer in the utility model or insulating barrier can adopt metal surface treatment technology in each conductor single line Surface Machining, form one deck weakly conducting or nonconducting thin layer, make the electric current that passes through between the conductor single line can reach the degree of ignoring, the electric current that passes through of every conductor single line will be about equally like this, greatly reduce the kelvin effect in the core, also can not increase proximity effect.The semi-conductive layer or the insulating barrier of this conductor single line outer surface will have enough mechanical strengths, so that bear the effect of the mechanical force that single line produced when stranded.
The utility model is owing to adopt the structure that semi-conductive layer or insulating barrier are set at each conductor single line outer surface, electric cable with large cross-section conductor for the big alternating current of transmission, both can adopt traditional regular stranded mode to process conductor wire core, can eliminate kelvin effect again, and save the expense of special equipment.

Embodiment
As shown in the figure: the utility model is by many conductor single lines 1 stranded forming, and is evenly equipped with semi-conductive layer or insulating barrier 2 at each conductor single line 1 outer surface.Semi-conductive layer in the utility model or insulating barrier can adopt metal surface treatment technology in each conductor single line Surface Machining, form one deck weakly conducting or nonconducting thin layer, make the electric current that passes through between the conductor single line can reach the degree of ignoring, the electric current that passes through of every conductor single line will be about equally like this, greatly reduce the kelvin effect in the core, also can not increase proximity effect.The semi-conductive layer or the insulating barrier of this conductor single line outer surface will have enough mechanical strengths, so that bear the effect of the mechanical force that single line produced when stranded.
