Product Details
Product features:
1. The electrical properties of aluminum clad steel core aluminum stranded wire include the conductivity of the aluminum clad layer in the aluminum clad steel wire, which is measured at 20 ℃
Meters of DC resistance. The resistivity of the hard aluminum wire used for the stranded wire is 28.264 n Ω · m.
2. The rated tensile strength of aluminum clad steel core aluminum stranded wire to form the tensile strength of the aluminum part of the aluminum clad steel core aluminum stranded wire and the aluminum cladding
The sum of the tensile resistance of the steel part is represented.
Corrosion resistance
Overhead wires are subjected to electrochemical corrosion in the atmosphere. In the steel core aluminum stranded wire, the coating on the surface of the steel core contacts the aluminum wire to form
Electrochemical corrosion, because the potential of the plating is lower than that of aluminum, results in the coating being quickly corroded, exposing the steel core to the atmosphere and being corroded.
In addition, after the coating is completely corroded, the steel core contacts the aluminum wire and forms electrochemical corrosion. The potential of aluminum is lower than that of iron, resulting in the aluminum wire being corroded again
Corroded.
