Abstract
The utility model discloses an energy-saving overhead wire for transmission project, which comprises a core wire and a conductive bare wire which is coated outside; the core wire is a stranded galvanized steel wire, the conductive bare wire is a plurality of layers of aluminum wire stranded outside the core wire, and the cross-sectional at the outer layer is in a fan shape. When compared with theconventional ACSR (steel-cored aluminum strand) of the same size, the line loss of the energy-saving overhead wire for transmission project can be reduced by about 3% when transmitting the same capacity power, the resource is saved; therefore, the transmission capacity of the energy-saving overhead wire for transmission project is increased by 50% or so than that of the conventional ACSR of the same size. Therefore, when the energy-saving overhead wire for transmission project is used, the purpose of saving energy and transmitting lager electrical current can be achieved under the circumstances that the original towers and the matched fittings are not changed, and the power grid construction investment can be saved.
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 aspects such as its structures, ampacity is little and line loss is bigger than normal, in order to increase the conveying capacity of lead, the sectional area that must increase lead is to strengthen the ampacity of lead.Like this, the power grid construction investment increases.
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 power transmission engineering energy-saving 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.
The energy-saving aerial condutor of a kind of power transmission engineering that the utility model provides comprises the conduction bare wire of heart yearn and outsourcing, and heart yearn is the galvanized steel wire of strands, and the conduction bare wire is several layers and is stranded in the outer aluminum steels of heart yearn that the cross section of outer field aluminum steel is fan-shaped.
The beneficial effects of the utility model are: the cross section of outer aluminum steel is being fan-shaped after pressing, closely contact each other, reduce the conductive line surfaces space, increased the conductive line surfaces smoothness, reduce the generation of corona, reduced the electric energy loss that causes because of corona discharge, compare with the conventional steel reinforced aluminium conductor of same size, it is about 3% to reduce line loss during transmission same capability electric energy, energy savings; And, can increase transmission capacity about 50% than the conventional steel reinforced aluminium conductor of same size.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, heart yearn, 2, the internal layer aluminum steel, 3, outer aluminum steel.
Embodiment
With reference to Fig. 1, galvanized steel wire with several Extra High Strengths is twisted into heart yearn 1 earlier, pressing mould with circle behind the stranded several layers of annealed aluminum wire again outside heart yearn 1 carries out drawing to outer aluminum steel 3 and presses, make the cross section of the aluminum steel 3 after pressing be fan-shaped, closely contact each other, smooth surface is smooth, and the space reduces, and promptly makes the utility model.
