AAC conductor, or all-aluminium conductor, is a stranded overhead conductor made from aluminium wires. To select one, compare the required cross-sectional area, strand construction, electrical resistance, outside diameter, mechanical loading, applicable standard, and project conditions—not just the product name. The right specification depends on the line design and local requirements, so buyers should confirm technical limits with the project engineer and request a drawing or data sheet from the supplier before ordering.
This guide is intended for utility buyers, electrical contractors, distributors, and project engineers sourcing bare overhead conductors. It can help you prepare a comparable specification and identify questions to resolve before placing an order. It is not a substitute for line-design calculations, local electrical codes, or approval by the responsible engineer.
AAC conductor consists of multiple aluminium wires stranded concentrically to form a bare conductor. Because its strands are aluminium, the conductor combines electrical conductivity with relatively low mass compared with many conductors that include a steel core. Its suitability for a specific line still depends on the required electrical capacity and mechanical design.
AAC carries electrical current in overhead power distribution and transmission applications where the project design permits its mechanical characteristics. It may be considered for distribution lines, substations, and other overhead installations, with the final choice determined by span length, loading, support structure, and applicable standards. AAC is not a communication cable and does not provide insulation; it must be used as part of a properly designed overhead line system.
A useful specification describes measurable requirements rather than relying on a size name alone. Standards, naming conventions, and available constructions can differ by market, so make the governing standard explicit in your inquiry. Ask the supplier to identify any differences between the requested standard and the offered product before approving a substitution.
| Specification | What to Check | Why It Matters |
|---|---|---|
| Conductor material | Aluminium material designation and applicable material requirements | Confirms that the offered conductor matches the specified product type. |
| Nominal cross-sectional area | Required area in mm² or the equivalent size designation used in the project | Supports comparison of electrical and dimensional requirements. |
| Stranding | Number and diameter of strands, or the specified construction drawing | Defines the conductor’s construction and helps verify the finished product. |
| Outside diameter | Specified diameter in mm and permitted tolerance | Can affect fittings, clearances, and compatibility with line hardware. |
| Electrical resistance | Maximum DC resistance in Ω/km, with the reference temperature stated | Provides a comparable electrical performance limit. |
| Mechanical properties | Required tensile or breaking-load values and applicable test basis | Helps determine whether the conductor suits the design loads. |
| Standard and inspection | Named standard, inspection requirements, and documents to be supplied | Reduces ambiguity during quotation, production, and acceptance. |
When comparing resistance, use the same reference conditions for every offer. For example, a buyer can specify that resistance values be reported at 20°C; this is a stated comparison condition, not a guarantee of any particular AAC resistance. The supplier’s data sheet should provide the actual declared value and the relevant tolerance under the applicable standard.
Confirm the operating requirements and the mechanical design inputs before choosing a conductor size. Relevant factors can include current demand, span length, support spacing, wind and ice loading, installation temperature, and required clearances. A larger cross-sectional area alone does not establish that the conductor is suitable for a particular route.
State the nominal area and required stranding, or request a supplier drawing for review. Confirm the outside diameter, tolerances, and compatibility with the specified clamps, connectors, and other hardware. If your project uses a local designation, provide the underlying dimensions or standard so the supplier can check equivalence.
Name the governing product standard in the inquiry and identify which tests, inspections, and documents are required. Standards can specify construction and test methods differently, so a generic statement such as “AAC, equivalent quality” may leave important points unresolved. Request written confirmation of deviations instead of assuming that products with similar size labels are interchangeable.

Consider the route environment and installation method, including exposure to pollution or corrosive conditions, handling requirements, and storage. Ask the engineer to confirm whether AAC is appropriate for the project’s mechanical and environmental constraints. Where additional strength or other performance characteristics are required, compare suitable conductor types rather than forcing AAC to meet a requirement outside the design basis.
Use a consistent checklist to make supplier quotations easier to compare. Begin with the technical scope, then evaluate delivery and commercial terms against the same requested quantity and destination. A request for quotation can state the quantity in km—for example, 10 km or 100 km as project examples—along with the required delivery schedule and packaging; these quantities are examples, not standard minimum order quantities.
AAC pricing can depend on aluminium market conditions, conductor size and construction, order quantity, packaging, and delivery terms. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed in a written quotation rather than assumed from a catalogue. For a useful comparison, ask every supplier to quote the same specification, quantity, destination, and delivery basis.
Also clarify whether the quotation covers the conductor only or includes specified drums, marking, inspection, and documentation. If your project requires phased deliveries, give the requested quantities and dates at the inquiry stage. This helps suppliers assess material planning and production capacity without implying that a particular schedule is guaranteed.
Ask potential suppliers to provide a technical data sheet, construction details, applicable standard, and a clear list of deviations from your specification. Confirm how the supplier identifies the product and order quantity on drums and shipping documents, and ask what inspection records can accompany the shipment. For project-critical requirements, agree on the approval process and acceptance criteria before production.
At Zhongdong Cable Co., Ltd., we support B2B buyers by reviewing AAC conductor requirements, clarifying specification details, and preparing quotations based on the requested construction and order scope. We encourage buyers to share the applicable standard, target size, quantity, destination, packaging expectations, and required documents. Our team can then confirm the product details and commercial terms available for the inquiry.
AAC conductor selection starts with the line design and a complete specification—not with a catalogue size alone. Define the nominal area, stranding, diameter, resistance reference, mechanical requirements, standard, and delivery scope, then compare supplier responses on the same basis. This approach helps you identify technical gaps and commercial differences before committing to an order.
To request an AAC quotation from Zhongdong Cable Co., Ltd., send your project specification or drawing, required quantity, delivery destination, preferred schedule, and documentation needs. If some details are not yet fixed, indicate which requirements are preliminary so we can clarify the open points with you before quotation.
