First, Application:

AAC and ACSR have been widely used in power transmission lines with vaious voltage levels,since they heve such good characteristics as simple structure, convention installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys where special geographical features exist.
