Full title and description

ASTM B836 − 00 (Reapproved 2021) — Standard Specification for Compact Round Stranded Aluminum Conductors Using Single Input Wire Construction. This specification defines the construction, classification, mechanical and electrical requirements, and permitted joints for compact round stranded aluminum conductors manufactured from single input wire (SIW) for use in covered or insulated electrical cables and wires.

Abstract

This standard covers compact round stranded aluminum conductors made from round or shaped single input wires (SIW) intended for subsequent insulation or covering. It specifies conductor constructions, limits on joints and splices, required mechanical and electrical tests of component wires, rated and breaking strength requirements, lay lengths, and ordering/marking information for purchasers and manufacturers.

Scope

This specification applies to SIW compact round stranded aluminum conductors intended to be covered or insulated for electrical applications. It covers conductor construction (including concentric and compact stranding patterns), acceptable jointing methods in individual wires (electric-butt welding, cold-pressure welding, electric-butt/cold-upset welding), limits on proximity of joints, rated and breaking strength determinations based on component wire properties, lay length requirements, and information that must be supplied when ordering material.

Key topics and requirements

• Definition and classification of SIW compact round stranded aluminum conductors.
• Permitted jointing and splicing methods for individual wires and restrictions on joint spacing.
• Construction tables and lay-length limits for various conductor sizes.
• Calculation and specification of rated-strength and breaking-strength values based on component-wire tensile properties.
• Requirements for pre-stranding testing of wire mechanical and electrical properties.
• Ordering information, marking, packaging, and inspection provisions.

Typical use and users

Used by cable and conductor manufacturers, electrical design engineers, procurement and specification writers, testing laboratories, and quality assurance personnel to ensure consistent manufacture and verification of compact round stranded aluminum conductors for insulated cable applications.
