Abstract
A steel-cored aluminium strand wire belongs to the technical field of electric power fittings, and aims to solve the technical problem that a steel-cored aluminium strand wire in the prior art has low tensile strength or high magnetic loss. The steel-cored aluminium strand wire adopts the structure that a non-magnetic steel conductor layer is stranded at the periphery of a central steel conductor, and an aluminium conductor is stranded outside the non-magnetic conductor layer. Compared with the prior art, the steel-cored aluminium strand wire provided by the utility model has remarkably enhanced tensile strength and extremely low magnetic loss.
Description
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to steel reinforced aluminium conductor.
Background technology
At present, steel reinforced aluminium conductor is widely used in the built on stilts electric line of various electric pressures.
Traditional steel reinforced aluminium conductor is by aluminum steel and steel wire is stranded forms, and its inside is steel core, and the outside is to be wrapped in around the steel core by stranded mode with aluminum steel.Steel core mainly plays a part to gain in strength, and aluminium stranded conductor mainly works to transmit electric energy.
Steel core can adopt single steel wire, because there is skin effect in alternating current in transmission course, adopting single steel wire is favourable to reducing magnetic loss, but can cause the little defective of tensile strength of steel reinforced aluminium conductor simultaneously.For improving the tensile strength of steel reinforced aluminium conductor, can adopt stranded steel core at the center of aluminium stranded conductor, the internal diameter of steel core expansion tensile strength has obtained raising really like this, but because there is magnetic loss in steel core itself, after using stranded steel core, make the magnetic loss of steel reinforced aluminium conductor sharply increase.
Summary of the invention
For this reason, it is not high that the purpose of this utility model is to solve steel reinforced aluminium conductor tensile strength of the prior art, if improve the technical problem that tensile strength then will inevitably cause magnetic loss to increase, thereby provide a kind of tensile strength the high little steel reinforced aluminium conductor of magnetic loss simultaneously.
The technical solution adopted in the utility model is as follows:
A kind of steel reinforced aluminium conductor, it comprises inner core and skin, and described inner core is the steel lead, and described skin is stranded aluminum conductor layer, also is provided with interlayer between described inner core and skin, and described interlayer is stranded nonmagnetic steel conductor layer.
Described nonmagnetic steel conductor layer, aluminum conductor layer are individual layer.
The internal diameter of described steel lead, nonmagnetic steel lead, aluminum conductor equates.
Described steel lead is 1, and described nonmagnetic steel lead is 6, and described aluminum conductor is 12.
The technical solution of the utility model has following beneficial technical effects compared to existing technology:
Steel reinforced aluminium conductor described in the utility model also is provided with interlayer between described inner core and skin, described interlayer is stranded nonmagnetic steel conductor layer.The structure of the single steel wire steel core compared to existing technology, stranded around the central steel lead have a nonmagnetic steel conductor layer, can enlarge markedly the tensile strength of steel reinforced aluminium conductor, and the aluminium stranded conductor of its tensile strength and the stranded steel core of available technology adopting is suitable.Simultaneously, adopt the aluminium stranded conductor of stranded steel core in compared to existing technology, owing to adopted the nonmagnetic steel lead, because skin effect is flowed through during described nonmagnetic steel conductor layer, magnetic loss is minimum when alternating current.
Description of drawings
For the utility model more is expressly understood, embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.Wherein,
Fig. 1 is the transverse cross-sectional view of steel reinforced aluminium conductor described in the utility model;
Reference numeral is expressed as among the figure: 1-steel lead, 2-nonmagnetic steel lead, 3-aluminum conductor.
Embodiment
As shown in Figure 1, steel reinforced aluminium conductor described in the utility model, it comprises inner core and skin, and described inner core is a steel lead 1, and described skin is 3 layers of stranded aluminum conductors, also is provided with interlayer between described inner core and skin, and described interlayer is 2 layers in a stranded nonmagnetic steel lead.
Described nonmagnetic steel lead 2, aluminum conductor 3 can be individual layer or sandwich construction.As preferred embodiment, 2 layers in described nonmagnetic steel lead, aluminum conductor are set in the present embodiment are individual layer for 3 layers.
Described steel lead 1, nonmagnetic steel lead 2, aluminum conductor 3 can be selected different specifications, and as preferred embodiment, the internal diameter that described steel lead 1, nonmagnetic steel lead 2, aluminum conductor 3 are set in the present embodiment equates.
Preferably, it is 1 that described steel lead 1 is set, and described nonmagnetic steel lead 2 is 6, and described aluminum conductor 3 is 12.
Stranded around the structure of the single steel wire steel core compared to existing technology, central steel lead 1 have 2 layers in a nonmagnetic steel lead, can enlarge markedly the tensile strength of steel reinforced aluminium conductor, and the aluminium stranded conductor of its tensile strength and the stranded steel core of available technology adopting is suitable.Simultaneously, adopt the aluminium stranded conductor of stranded steel core in compared to existing technology, owing to adopted nonmagnetic steel lead 2, because skin effect is flowed through during described nonmagnetic steel conductor layer, magnetic loss is minimum when alternating current.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give to all execution modes exhaustive, and the conspicuous variation of being extended out thus or the change still be among the protection range of the utility model claim.
