Abstract
The utility model belongs to the technical field of the electric power transportation, concretely relates to novel inferior light aluminium conductors (cable) steel -reinforced without surface treatment. A central be steel strand wires (1) of novel inferior light aluminium conductors (cable) steel -reinforced without surface treatment is proposed, the outside winding of steel strand wires (1) has the inferior light aluminum wire transposition layer (3) of one deck as conductive element, the winding direction on inferior light aluminum wire transposition layer (3) is dextrad. The utility model discloses the light pollution of special occasion has been avoided, moreover because noise and dust pollution have been avoided in special drawing process's use in the manufacture process.
Description
Technical field
The utility model belongs to electric power transportation technology field, is specifically related to the not surface treated novel sub-light steel-cored aluminium strand of one.
Background technology
For special occasions such as airports, when takeoff and landing, driving cabin broad view, unobstructed, most important to pilot's safe flight without light pollution; For the impact on pilot driver of the reverberation that effectively reduces Adjacent Buildings and peripheral facility thereof, thereby avoid the potential safety hazard that takeoff and landing are brought, relevant departments propose certain requirement to the surface reflection degree of airport peripheral facility; These facilities comprise airport transmission line of electricity around; Traditional overhead transmission line surface is bright minute surface, and for above-mentioned special occasions, be necessary the matt surface overhead transmission line that adopts surface reflection degree low, to reduce to greatest extent the sunshine of overhead transmission line surface reflection, thereby reduce light pollution, pilot impacted when the aircraft takeoffs and landings; In some American-European countries, require must use under the special occasions such as airport the overhead transmission line of matt surface; The sub-light overhead transmission line having had at present reaches matt effect by common overhead transmission line is carried out to surface treatment, and the method has noise and dust pollution in process of production.
Utility model content
In order to make up above weak point, the purpose of this utility model is to propose the not surface treated novel sub-light steel-cored aluminium strand of one.
The utility model adopts following technical scheme for completing above-mentioned purpose:
The not surface treated novel sub-light steel-cored aluminium strand of one, the center of described novel sub-light steel-cored aluminium strand is steel strand wires; The outer felt of described steel strand wires is wound with the sub-light aluminum steel stranded layer of one deck as conducting element; The winding direction of described sub-light aluminum steel stranded layer is dextrad.
Between described steel strand wires and described sub-light aluminum steel stranded layer, be provided with aluminum steel stranded layer; Described aluminum steel stranded layer mostly is three layers most; The winding direction of adjacent two layers aluminum steel stranded layer is contrary, and the winding direction of outermost layer aluminum steel stranded layer is left-hand.
Described steel strand wires form by galvanized steel wire is stranded.
Described aluminum steel stranded layer is by stranded the forming of one or more layers aluminium single line solid matter.
Described sub-light aluminum steel stranded layer is by stranded the forming of the sub-light aluminum steel solid matter of one deck.
The tensile strength of described sub-light aluminium single line stranded layer is identical with tensile strength and the electric conductivity of aluminum steel stranded layer with electric conductivity, and conductance reaches 61%IACS.
The not surface treated novel sub-light steel-cored aluminium strand of the one the utility model proposes, adopt such scheme, when making the combination property of novel sub-light steel-cored aluminium strand can match in excellence or beauty conventional steel core aluminum stranded wire completely again for the skin of steel-cored aluminium strand provides matt surface, avoided the light pollution of special occasions, and in manufacture process because noise and dust pollution have been avoided in the use of special drawing process.
Brief description of the drawings
Fig. 1 structural representation of the present utility model.
In figure: 1, steel strand wires, 2, aluminum steel stranded layer, 3, sub-light aluminum steel stranded layer.
Detailed description of the invention
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, the not surface treated novel sub-light steel-cored aluminium strand of one, the center of described novel sub-light steel-cored aluminium strand is steel strand wires 1; The outer felt of described steel strand wires 1 is wound with the sub-light aluminum steel stranded layer 3 of one deck as conducting element; The winding direction of described sub-light aluminum steel stranded layer 3 is dextrad.
Between described steel strand wires 1 and described sub-light aluminum steel stranded layer 3, be provided with aluminum steel stranded layer 2; Described aluminum steel stranded layer 2 mostly is three layers most; Aluminum steel stranded layer 2 described in this embodiment is two-layer; The winding direction of adjacent two layers aluminum steel stranded layer 2 is contrary, and the winding direction of outermost layer aluminum steel stranded layer 2 is left-hand.
Described steel strand wires 1 form by galvanized steel wire is stranded.
Described aluminum steel stranded layer 2 is by stranded the forming of one or more layers aluminium single line solid matter; Described aluminum steel stranded layer 2 belongs to the conducting element of novel sub-light steel-cored aluminium strand, there is certain tensile strength and good electric conductivity, thereby can improve the overall tensile strength of novel sub-light steel-cored aluminium strand for novel sub-light steel-cored aluminium strand provides axial resistance to tension in conduction, electric conductivity is superior, is the desirable aerial condutor conductor material of commonly using.
Described sub-light aluminum steel stranded layer is by stranded the forming of the sub-light aluminum steel solid matter of one deck; The tensile strength of described sub-light aluminium single line stranded layer is identical with tensile strength and the electric conductivity of aluminum steel stranded layer with electric conductivity, and conductance reaches 61%IACS.
