ASTM B231 Aluminum 1350 Concentric-Lay-Stranded Conductors Standard
Standard Overview
ASTM B231-18 covers the requirements for concentric-lay-stranded aluminum 1350 conductors used for electrical applications. The standard specifies the requirements for conductor construction, dimensions, mechanical properties, and electrical performance.
It is widely applied to AAC (All Aluminium Conductor) used in overhead power transmission and distribution systems.
Key Requirements
Conductors made from 1350-H19 aluminum wires
Concentric stranded construction with multiple layers of aluminum wires
Defined conductor diameter, resistance, and tensile strength requirements
Applicable for overhead electrical conductors
Applications
Used for overhead distribution lines, power transmission networks, and utility infrastructure projects.
