Description :

　　The difference between steel strand aluminum clad conductors and aluminum conductors lies in their steel cores. The steel core of the steel core aluminum core is made of galvanized steel wire, while the aluminum clad steel wire in the aluminum clad aluminum conductor is a type of bimetallic wire. Using high temperature and high pressure continuous extrusion of electric aluminum on high-strength steel wire, aluminum and steel form a permeable layer of 8m thick aluminum steel, coating the steel wire with aluminum layer, and then light bimetallic synchronous deformation. Ionic machine. After multiple pulls, aluminum and steel deform proportionally, making the infiltration layer of aluminum and steel more uniform and firm.

　　The specifications of insulated overhead lines, aluminum clad steel stranded wires and other products are complete, and all performance meets national standards. Secondly, introduce the characteristics of aluminum clad aluminum stranded wire and steel core aluminum stranded wire.

　　1. Mechanical and mechanical properties

　　(1) The structural dimensions and mechanical properties of aluminum clad aluminum stranded wire and steel core stranded wire are the same, but the weight of aluminum clad aluminum stranded wire is about 5% lighter than steel core wire, so it can be a 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.

　　(2) Aluminum clad steel aluminum wire at 20 ℃

　　(3) The DC resistance of aluminum stranded wire C is about 3.2% lower than that of steel aluminum wire. The fracture force of Rad steel wire is about 5.5% lower than that of steel aluminum wire.

　　2. Corrosion resistant overhead conductors are subjected to electrochemical corrosion in the atmosphere, and in steel core aluminum conductors, the surface of the steel core comes into contact with the aluminum conductor. Electrochemical corrosion is caused by the lower potential of the coating compared to aluminum, leading to rapid corrosion of the coating and exposing the steel core to corrosion in the atmosphere. After the coating corrodes, the steel core comes into contact with the aluminum wire. Electrochemical corrosion, where the potential of aluminum is lower than that of iron, leads to corrosion of aluminum wire. For aluminum clad aluminum conductors, there is a good metallurgical bond between the aluminum and steel in the aluminum clad steel wire, and the single wire in the stranded wire has a good metallurgical bond. The contact between aluminum does not cause electrochemical corrosion between different metals, which can greatly reduce the corrosion rate of metal wires and extend their service life. It can be said that the corrosion resistance of aluminum clad steel.
