aluminum’s softness and oth er properties, the overh ead aluminum conductors are commo nly used
with steel cores. The aluminum conductor , steel-reinforced (ACS R) cable standards are covered by
Standards ASTM B232/232M, ASTM B401, AST M B549, ASTM B701/701M and ASTM B77 9.
Other reinforced forms of aluminum aerial conductors include: Aluminum Conductor,
Aluminum-Alloy Reinforced (ACAR); Aluminum-Alloy Conductor, Steel Reinforced
(AACSR); Aluminum Conductors, Coated Steel Supported (ACSS); and Aluminum
Conductors, Aluminum-Clad-Steel Reinforced (ASCR/AW). The reinforced conductors allow
longer spans between supports and provide added support for
