AAC Bare Conductor (All Aluminium Conductor)

How to Select the Right AAC Conductor Size

Selecting the correct AAC conductor size requires a balance between electrical performance and the mechanical conditions of the overhead line. Before specifying a conductor, consider the following factors:

1. Required Electrical Load

Start with the required current-carrying capacity and acceptable voltage drop. A larger conductor cross-section generally provides lower electrical resistance and supports higher current requirements, but also increases conductor weight and project cost.

2. DC Resistance

Check the DC resistance at 20°C (Ω/km) in the technical data table. Lower resistance helps reduce transmission losses, making conductor resistance an important factor when comparing AAC sizes for continuous-load applications.

3. Span and Mechanical Requirements

AAC provides high conductivity but does not contain a steel reinforcement core. Conductor size should therefore be checked together with span length, rated tensile strength, sag requirements, wind load and other mechanical conditions of the overhead line.

4. Applicable Standard

Confirm the required conductor standard before ordering. Zhongdong can supply AAC conductors according to standards such as IEC 61089, ASTM B231 and BS 215-1, with conductor dimensions, stranding and performance matched to project specifications.

Before Requesting a Quote

For faster AAC conductor selection and quotation, please provide:

• Required standard

• Nominal cross-sectional area

• Required current or system load

• Span and installation conditions

• Required conductor length

• Destination market or project requirements

Refer to the AAC conductor specification table below to compare conductor area, stranding, diameter, linear mass, breaking load and DC resistance. If the required size is not listed, contact Zhongdong with your project specifications for technical confirmation.
 

AAC Conductor Quality Control & Testing

AAC conductors are inspected throughout production to verify electrical performance, mechanical strength and dimensional consistency before shipment.

Key Quality Checks

• Aluminium wire inspection – verifies wire diameter, surface condition and material consistency before stranding.

• Conductor diameter and stranding inspection – checks overall dimensions, number of wires, lay direction and strand uniformity.

• DC resistance test – measures conductor resistance at 20°C to confirm compliance with the specified electrical performance.

• Tensile and breaking load test – evaluates the mechanical strength of the finished conductor against project or standard requirements.

• Surface inspection – checks for scratches, burrs, loose strands or other defects that may affect installation and service performance.

• Final dimensional inspection – confirms conductor size, linear mass and other specified parameters before packing.

AAC conductors can be manufactured and inspected according to applicable standards such as IEC 61089, ASTM B231 and BS 215-1. Test records and required inspection documents can be provided according to order and project requirements.

For bulk orders, buyers can specify the required standard, conductor size, inspection items and documentation requirements before production.

When Should You Choose AAC Conductor?

AAC conductor is a suitable choice when a project prioritizes high electrical conductivity, low conductor weight and corrosion resistance, especially for short- to medium-span overhead distribution lines.

AAC is commonly selected when:

• High conductivity is important and low electrical resistance is required.

• Span lengths are relatively short and very high mechanical strength is not the primary requirement.

• Lower conductor weight can simplify handling, installation and supporting structure requirements.

• The line is installed in urban distribution, industrial power networks or substation connections.

• Good resistance to atmospheric corrosion is required in normal outdoor service conditions.

For projects with longer spans or higher mechanical loads, AAAC Conductor or ACSR Conductor may be more suitable because they provide greater mechanical strength. Buyers can compare these conductor types according to span, tensile load and installation environment before specifying the final design.

The final conductor selection should consider electrical load, span length, sag, wind and ice loading, installation environment and the applicable project standard.

How to Specify AAC Conductor for Your Project

To receive an accurate AAC conductor quotation and technical confirmation, provide the key project requirements below:

• Applicable standard – such as IEC 61089, ASTM B231 or BS 215-1.

• Conductor size – specify the required cross-sectional area, AWG or kcmil size where applicable.

• Stranding requirement – confirm the required wire number and conductor construction if specified by the project.

• Required quantity – provide the total conductor length or project demand.

• Drum length and packing – indicate preferred delivery length per drum and any special packing requirements.

• Installation conditions – include span length, environmental conditions or other relevant line requirements when technical confirmation is needed.

• Destination country – helps confirm applicable standards, packing and shipping requirements.

• Required documents – specify test reports, inspection records, certificates or other project documentation required with the order.

For non-standard AAC conductor specifications, send your technical data sheet, drawing or project requirements to Zhongdong for review before production.
