Discussion on the Advantages of Aluminum Clad Steel Core Aluminum Strand

2021-07-12
Aluminum-clad steel core aluminum stranded wire is a hollow wire made of aluminum-clad steel wire, which is composed of a reinforced core and a hard aluminum wire. Compared with the general steel-core aluminum stranded wire, the aluminum-clad steel-core aluminum stranded wire is lighter 5, the cable current carrying capacity is increased by 2-3, the sag is reduced by 1-2, the power loss is reduced by 4-6, the corrosion resistance effect is good, the service period is long, the structure is simple, the stringing and maintenance are convenient, and the transmission capacity is large.
Aluminum-clad steel core aluminum stranded wireThe difference between the conductor and the aluminum conductor is that their steel core is different. The steel core of the aluminum-clad steel core aluminum stranded wire is made of galvanized steel wire, and the aluminum-clad steel wire in the aluminum-clad aluminum conductor is a kind of double gold. High-temperature and high-pressure continuous extrusion of high-strength steel wire on the electric aluminum, so that aluminum and steel form a permeable layer of 8m thick aluminum steel, coated with aluminum layer of steel wire, and then light bimetal synchronous deformation. Ion machine. After repeated drawing, aluminum and steel are deformed in proportion to make the seepage layer of aluminum and steel more uniform and firm.

It is widely used in distribution lines of various voltages and needs to increase the load-to-surface ratio of aluminum to steel. It can also be used for transmission lines in coastal areas, salt-alkali beaches and industrial pollution areas of grade three and four.
Insulated overhead line, aluminum-clad steel core aluminum stranded wire and other product specifications are complete, the performance of the national standards,Aluminum-clad steel core aluminum stranded wire manufacturersThe following describes the characteristics of aluminum-clad aluminum stranded wire and steel core aluminum stranded wire.
1 mechanical properties and mechanical properties.
The structural size and mechanical properties of the aluminum-clad steel-core aluminum stranded wire and the steel-core stranded wire are the same, but the weight of the aluminum-clad aluminum stranded wire is about 5 lighter than the steel-core wire, so it can be called conc. The two horizontal wind loads are the same, but The vertical load of the former is about 5 lower than that of the latter.
Aluminum clad steel aluminum conductor at 20 C.
The DC resistance of aluminum stranded wire c is about 3.2 times lower than that of steel aluminum wire. The breaking force of Lad steel wire is about 5.5 times lower than that of steel aluminum wire.
2. The high-voltage conductor of the anti-erosion overhead line is deeply subjected to crevice corrosion in the atmospheric environment. In the steel-core aluminum superconductor, the surface of the steel core touches the aluminum high-voltage conductor. Crevice corrosion is because the electrode potential after plating is lower than that of aluminum, which promotes rapid corrosion after plating, exposing the steel core to be corroded in the atmospheric environment, and after plating is corroded, the steel core touches the aluminum wire. Crevice corrosion, the electrode potential of aluminum is not super iron, prompting the aluminum wire to be corroded. For aluminum-clad aluminum superconductors, aluminum and steel in the aluminum-clad steel wire have a good mining and metallurgical cooperation, and the single wire in the stranded wire has a good mining and metallurgical cooperation. In the middle of the aluminum touch, there is no crevice corrosion between them in the different metals, which can greatly reduce the corrosion depth of the metal and increase its service life, which can be said to be the wear resistance of aluminum clad steel.
The above is a basic overview of the advantages of aluminum clad steel core aluminum stranded wire. Interested friends can refer to it by themselves. If there is anything elseSteel-reinforced aluminum stranded wire, overhead insulated conductorIf you want to know, you can consult us.
