　　 What is aluminum clad steel core aluminum stranded wire

　　Aluminum clad steel wire, also known as aluminum clad steel core aluminum stranded wire, is an overhead conductor composed of aluminum clad steel wire as a reinforcing core and hard aluminum wire twisted together. Compared with ordinary steel cored aluminum stranded wire, aluminum clad steel cored aluminum stranded wire is 5% lighter in weight, 2-3% higher in current carrying capacity, 1-2% less sag, 4-6% less power loss, and has good anti-corrosion performance, long service life, simple structure, easy installation and maintenance, and large transmission capacity.

　　Aluminum clad steel wire and its characteristicspoint

　　Aluminum clad steel wire is a bimetallic wire that is uniformly, continuously, and tightly wrapped around a round steel wire with a layer of aluminum. Aluminum has relatively low strength but is relatively light, with a density of about one-third that of copper. Its electrical conductivity is relatively high, ranking third after silver and copper. Aluminum has better corrosion resistance: steel has higher strength, but lower electrical conductivity and corrosion resistance. Therefore, aluminum clad steel wire is the product of the strong combination and strong weak complementarity of aluminum and steel.

　　Product performance

　　The electrical properties of aluminum clad steel cored aluminum stranded wire include the conductivity of the aluminum coating in the aluminum clad steel wire, expressed as its kilometer DC resistance at 20 ℃. The resistivity of the hard aluminum wire used for the stranded wire is 28.264 n Ω· m.

　　The rated tensile strength of 2 aluminum clad steel core aluminum stranded wire is expressed as the sum of the tensile strength of the aluminum part that makes up the aluminum clad steel core aluminum stranded wire and the tensile strength of the aluminum clad steel part.

　　Execution standard: GB/T 1179-2008 "Round Wire Concentric Twisted Frame Empty Wire".

　　 Aluminum clad steel cored aluminum stranded wire and steel cored aluminum stranded wire have the same structural dimensions and mechanical properties, but the unit length weight of aluminum clad steel cored aluminum stranded wire is about 5% lighter than that of steel cored aluminum stranded wire. From this, it can be concluded that the horizontal wind load of the two is the same, but the vertical load of the former is reduced by about 5% compared to the latter.

　　The DC resistance of aluminum clad steel cored aluminum stranded wire at 20 ℃ is about 3.2% lower than that of steel cored aluminum stranded wire; The guaranteed breaking force of aluminum clad steel cored aluminum stranded wire is about 5.5% lower than that of steel cored aluminum stranded wire.

　　 Overhead power lines are subjected to electrochemical corrosion in the atmosphere. In steel core aluminum stranded wire, the coating on the surface of the steel core comes into contact with the aluminum wire to form electrochemical corrosion. Because the potential of the coating is lower than that of aluminum, the coating is quickly corroded, exposing the steel core to the atmosphere and causing corrosion. In addition, after the coating is completely corroded, electrochemical corrosion occurs when the steel core comes into contact with the aluminum wire. The potential of aluminum is lower than that of iron, resulting in corrosion of the aluminum wire again.

　　For aluminum clad steel core aluminum stranded wire, due to the good bonding between aluminum and steel in the aluminum clad steel wire, the single wires in the stranded wire are in contact with aluminum, and there is no electrochemical corrosion between different metals. This can greatly slow down the corrosion rate of the wire and extend its service life.

　　It can be said that corrosion resistance is the advantage of aluminum clad steel cored aluminum stranded wire.
