　　Analysis and Introduction of Steel cored Aluminum Stranded Wire:

　　 Steel cored aluminum stranded wire is equipped with advantages such as high conductivity, good thermal stability, low sag, and self damping. High voltage transmission lines are a necessary means of transporting electricity from the generating end to the receiving end, and overhead transmission lines play an extremely important role in them.

　　 The characteristics of using steel cored aluminum stranded wire for high-voltage transmission lines are as follows:

　　1. The steel core bears the mechanical load of the wire, while the main contribution of the aluminum wire strand to the wire is to carry current but not mechanical load. Therefore, the operating temperature of the wire will not be limited due to the softening characteristics of the aluminum wire strand. The operating temperature is completely determined by the softening characteristics of the steel core, and the recrystallization temperature of the steel core is higher, which can maintain normal mechanical strength at higher temperatures.

　　2. It has good anti-corrosion performance and thermal stability, and can operate at temperatures up to 250 ° C for a long time without reducing its mechanical strength. Under high temperature working conditions, its galloping degree does not show significant changes. It also has sub damping characteristics, which are beneficial for reducing wind induced vibrations and minimizing line losses in transmission lines.

　　Finished product display:

　　The cross-section of steel cored aluminum stranded wire is generally selected based on the economic current density, and should be verified according to the heating conditions, voltage loss, mechanical strength, and corona under accident conditions. When necessary, determine through technical and economic comparisons; But for lines of 110KV and below, corona discharge is often not the determining factor in choosing the wire cross-section.

　　1) Select wire cross-section based on economic current density

　　The transmission capacity used for selecting wire cross-sections based on economic current density should take into account the development plan of the power system for 5-10 years after the line is put into operation. In the calculation, it is necessary to use loads that frequently occur under normal operating conditions. But in the case where the system is not yet clear, care should be taken not to choose a wire cross-section that is too small.
