1、 Introduction to Aluminum conductor steel reinforced:


Aluminum conductor steel reinforced, abbreviated as ACSR, is a common material for overhead conductors. It is composed of aluminum wires and steel cores, and is widely used in the field of power transmission and distribution due to its good electrical conductivity, high strength, and mechanical stability.


2、 The main function of steel core:


Steel core is an important component of Aluminum conductor steel reinforced, and its main functions are focused on the following aspects:


1. Increase the strength and stability of the wire


Due to the addition of steel cores, the strength of the entire wire has been greatly improved. During the installation process, the steel core can also reduce the tensile deformation of the wire, thereby increasing its stability and preventing excessive elongation deformation, buckling deformation, etc.


2. Reduce the expansion and contraction of the wire core


Under the influence of atmospheric temperature difference, the core of the wire will experience expansion and contraction, which may even affect the safety of the wire. The presence of steel core can reduce the thermal expansion and contraction deformation of the wire core, overcoming the deformation and displacement caused by the influence of temperature on the wire.


3. Enhance the load-bearing capacity and safety of the wire


The addition of steel core can improve the load-bearing capacity and safety of the wire, increase the bending stiffness and fatigue resistance of the wire. Under strong winds and adverse weather conditions, the presence of steel cores can also enhance the tensile strength of wires, preventing dangerous situations such as wire breakage or collapse.


3、 Summary


In summary, the steel core is an important component of Aluminum conductor steel reinforced and plays a crucial role. It can increase the strength and stability of the wire, reduce the expansion and contraction of the wire core, and enhance the load-bearing capacity and safety of the wire. Special attention should be paid when using, selecting the correct wire specifications and usage methods to ensure the safe and stable operation of the wire.
