AAC all aluminium conductor stranded construction

AAC All Aluminium Conductor

AAC conductor is a concentric-lay bare conductor made entirely from hard-drawn aluminium wires. It is intended for overhead distribution and other routes where electrical conductivity and low conductor mass matter more than steel-core reinforcement. Standard constructions and project-specific strand arrangements can be reviewed against the required span, loading and delivery conditions.

Key Advantages

Efficient current path: Every strand contributes to electrical conduction.
Lower conductor weight: No steel core is included in the construction.
Straightforward specification: Select by standard, code word, size and strand arrangement.

Product Overview

An AAC conductor has a uniform all-aluminium cross-section, normally formed from round hard-drawn aluminium wires in concentric layers. Because it contains no separate reinforcing core, its installed performance is governed by the aluminium wire properties, total metallic area, strand pattern and finished diameter.

AAC is therefore best evaluated for lines with moderate mechanical duty. It can provide an attractive combination of conductivity and low mass, but it should not be substituted for a steel-reinforced conductor without checking span, wind and ice loads, sag, clearances and the selected hardware system.

Key Features

All-aluminium construction provides a continuous conductive section without a ferrous core.
Lower mass than comparable steel-reinforced constructions can reduce conductor dead load.
Aluminium-only construction removes steel-core corrosion from the conductor design, although fittings and the full environment still require review.
Construction tables are available under several national and international standard systems; code words and nominal areas are not automatically interchangeable.

Product Applications

Urban and rural overhead distribution with moderate span and loading requirements
Short- and medium-span lines where low conductor mass is valuable
Routes where an all-aluminium construction is preferred after corrosion and mechanical assessment

From Production to Delivery

From raw material preparation to final shipment, every stage is carefully controlled to ensure consistent conductor quality, reliable performance, and safe delivery. Our production, inspection, packaging, and logistics processes are managed in accordance with applicable standards and project requirements.

Production

Hard-drawn aluminium wire is drawn to the specified diameter and concentrically stranded to the required wire count and lay arrangement.

Inspection

Inspection focuses on wire diameter, surface condition, strand count, finished diameter and the construction-table values required by the selected standard.

Packaging

Finished AAC is wound onto drums with secured conductor ends and identification matched to the standard, conductor code and ordered length.

Shipping

Drum and document checks are completed before loading so the packing list, identification and supplied lengths remain traceable during export shipment.

Frequently Asked Questions

Is AAC the right choice when a line has long spans or heavy ice loading?

Not automatically. AAC has no reinforcing core, so the line designer must confirm tensile load, sag, wind and ice duty before selection. AAAC or a reinforced conductor may be more suitable where mechanical demand is higher.

What information is needed to match an AAC code word or size?

State the governing standard and edition, code word or nominal area, required strand construction, quantity, drum length and any dimensional, testing or packing requirements.

How should AAC be compared with AAAC?

Compare the actual conductor tables rather than the abbreviations alone. AAAC uses aluminium-alloy wire to obtain a different strength-conductivity balance, while AAC uses hard-drawn aluminium and generally places greater emphasis on conductivity.

Can existing ACSR fittings be reused for AAC?

Only after dimensional and mechanical checks. Clamp bore, conductor diameter, rated strength, compression system and installation instructions must match the selected AAC construction.

Which tests should be agreed for an AAC order?

The inspection plan should follow the purchase specification and applicable standard. Typical checks cover wire and conductor dimensions, strand construction, electrical resistance, surface condition and mechanical requirements where specified.

Does an AAC catalogue value replace a line-design calculation?

No. Catalogue data supports product selection, but final suitability still depends on route-specific sag-tension, loading, clearance, thermal and hardware calculations.
