General:
ACSR is made of a hard round aluminum and galvanized steel wire formed by stranding. It is the most commonly used conductor in the transmission and distribution lines. The ratio of steel section to aluminum section in the ACSR is called steel ratio. The larger the steel ratio, the higher the strength of the conductor. It can be applied to a large span on the line or used as overhead ground wire lines. Bundled conductors are widely used in EHV lines in modern power grid, greatly increasing the proportion of conductors in construction investment of the line. Therefore, a reasonable choice of conductor wire structure can effectively save the investment of the line and reduce the cost of the line.
Specification Range:
10/2-1440/135mm2
Main Applications:
Overhead lines of medium, high and extra high voltage
USA Sizes ASTM B232 Overhead Conductor Steel Reinforced ACSR Bobolink
Properties
In comparison with copper, these conductors have considerable technical and economical advantages in the installation of overhead lines. Its characteristics, and low weight, combined with its high break1ng strength, are gathered which makes it possible to have large span runs, without having to revert to excessive mechanical stresses or to heavy metallic Towers. Due to the greater diameter of the conductors, electric losses by the corona Effect are greatly reduced. By making use of these properties economical electric energy transmission is attained at very high voltages and distances.
Main applications: Overhead lines of medium, high and very high voltages.
