Standard Overview
AS/NZS 1531 specifies requirements for aluminium and aluminium alloy conductors used for overhead electrical lines. The standard covers the construction, dimensions, mechanical properties, and electrical characteristics of bare overhead conductors used in power transmission and distribution systems.
It is mainly applied in Australia, New Zealand, and related markets for overhead line conductors, including AAC and AAAC conductors
Key Requirements
Conductor Type: Bare stranded overhead conductors
Materials: Aluminium and aluminium alloy wires
Construction: Concentric stranded conductor design
Requirements: Conductor dimensions, electrical resistance, tensile strength, and material properties
Applicable Voltage: Used in overhead distribution and transmission networks
Applications
Used for overhead power distribution lines, transmission networks, rural electrification, and utility infrastructure projects.
