477 MCM PELICAN ACSR Conductor Cable
ASTM B232
Aluminium has become widely adopted as an electrical conductor material, largely due to its favorable electrical properties. However, for most long-span transmission lines, aluminium conductors require additional mechanical support—galvanized steel wires are commonly used as the core in ACSR conductors to address this need.
