Application
This type of conductor exhibits a superior strength-to-weight ratio compared to AAC, allowing it to be suitable for longer spans and more challenging weather conditions. Additionally, it boasts a higher modulus of elasticity and a lower coefficient of thermal expansion, both of which enhance its mechanical properties. These characteristics can be tailored by adjusting the aluminum-to-steel ratio in the stranding geometry. The use of higher strength steel further improves the strength-to-weight ratio without compromising other properties.
While ACSR may incur higher costs than AAC for a given current rating, its mechanical advantages make it economically superior when considering the entire line. It is due to this reason that ACSR is currently the most widely employed conductor type.
