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.
