Abstract
A low-loss overhead conductor comprises a core wire and an outer-coated conducting wire, wherein the core wire is a multi-strand stranded steel wire, the conducting wire is a plurality of layers of aluminum wires stranded outside the core wire, and the cross section of each aluminum wire is in a fan shape. The utility model has the advantages that the clearance between each aluminum wire is reduced, the wire loss of the conducting wire is reduced, and the energy is saved; compared with the conventional steel-cored aluminum stranded wire with the same specification, the current-carrying capacity of the wire can be improved. Therefore, use the utility model discloses, do not change original tower of setting up and just can reach energy-conservation and carry the purpose of more heavy current under the circumstances of supporting gold utensil, save the electric wire netting construction investment.
Description
Technical field
The utility model relates to a kind of lead, especially the power transmission engineering aerial condutor.
Background technology
Existing conventional aerial condutor---the steel reinforced aluminium conductor of using as power transmission engineering because the cross section of its aluminum conductor be a circle, is twisted into behind the aluminium stranded conductor and has certain clearance between the lead, and line loss in service heating bigger than normal, easy influences the ampacity of lead.
Summary of the invention
In order to overcome the deficiency of existing power transmission engineering with steel reinforced aluminium conductor, the utility model provides a kind of low-loss aerial condutor, the conventional steel reinforced aluminium conductor of comparable same size increases the ampacity of lead, when transmitting the same capability electric energy, the conventional steel reinforced aluminium conductor with same size can reduce line loss, energy savings.
A kind of low-loss aerial condutor that the utility model provides comprises the conductor wire of heart yearn and outsourcing, and heart yearn is the steel wire of strands, and conductor wire is several layers and is stranded in the outer aluminum steels of heart yearn that the cross section of every aluminum steel is fan-shaped.
The beneficial effects of the utility model are: the cross section of aluminum steel is fan-shaped, and stranded back is closely contact each other, and the gap between every aluminum steel reduces, and the line loss of lead reduces, energy savings; Compare with the conventional steel reinforced aluminium conductor of same size, can improve the ampacity of lead.Therefore, use the utility model, just can reach purpose energy-conservation and that carry bigger electric current not changing under original situation of setting up shaft tower and supporting gold utensil, the saving power grid construction is invested.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, fan-shaped electrical aluminium wire, 2, heart yearn.
Embodiment
With reference to Fig. 1, earlier several galvanized steel wires or aluminium-clad steel wire are made heart yearn 2, stranded several layers of fan-shaped electrical aluminium wire 1 outside heart yearn 2 are promptly made the utility model again.
Claims (1)
1. low-loss aerial condutor comprises the conductor wire of heart yearn and outsourcing, and heart yearn is the steel wire of strands, and conductor wire is several layers and is stranded in the outer aluminum steels of heart yearn, it is characterized in that the cross section of every aluminum steel is fan-shaped.
