New Specification for Concentric-Lay-Stranded Thermal-Resistant Aluminum Conductors, Steel Reinforced (ZTACSR)
1. Scope
This specification covers concentric-lay-stranded conductors made from round thermal-resistant aluminum-zirconium alloy wires and round steel core wire(s) for use an overhead electrical conductors
ZTACSR is manufactured and used in the utility industry but does not exist in any ASTM standard. An ASTM standard is necessary to guide producers and users on the material, manufacturing, and test requirements.
