ASTM B232 Aluminum Conductor Standard

Standard Overview

ASTM B232 specifies requirements for concentric-lay-stranded aluminum conductors reinforced with coated steel wires (ACSR) used for overhead electrical transmission and distribution lines.

The standard defines the requirements for conductor materials, construction, dimensions, mechanical strength, and electrical characteristics. ACSR conductors are widely used where high tensile strength and long-span capability are required.

Key Requirements

Conductor Type: Aluminum Conductor Steel Reinforced (ACSR)

Construction: Aluminum 1350-H19 wires stranded around a coated steel core

Core Material: Galvanized, aluminum-coated, or zinc-coated steel wires according to design requirements

Requirements: Conductor diameter, electrical resistance, tensile strength, and weight

Application: Overhead transmission and distribution systems

Applications

Used for overhead power transmission lines, long-span crossings, utility networks, and high-capacity distribution systems.
