Low-Voltage AWA Armoured Cable: Selection Guide, Specifications, and Applications
Low-voltage AWA armoured cable is an insulated power cable protected by aluminium wire armour, commonly selected for single-core circuits where mechanical protection is needed without using magnetic steel armour around an individual AC conductor. We recommend choosing it by checking the system voltage, conductor material and size, insulation, installation environment, fault requirements, and applicable project standard—not by armour type alone. A common low-voltage rating is 0.6/1 kV, but the exact rating and construction must match the project specification. At Zhongdong Cable Co., Ltd., we help buyers clarify these requirements before requesting a product quotation.

Who This Guide Is For
This guide is for electrical contractors, distributors, project engineers, and procurement teams evaluating low-voltage AWA cable for power distribution. It is especially relevant when a project calls for a single-core cable with armour and the design team is comparing aluminium wire armour with other protection options. It can also help buyers prepare a complete technical inquiry for a manufacturer. Final selection should be checked against local electrical regulations and the engineer’s approved design.
What Is Low-Voltage AWA Armoured Cable?
AWA means aluminium wire armour: a layer of aluminium wires placed around the cable’s inner bedding or sheath to provide mechanical protection. The cable also includes a conductor, electrical insulation, and usually one or more protective outer layers, with the precise construction depending on the specification. In many power-cable designs, AWA is used on single-core AC cables because aluminium is non-magnetic. This helps avoid the concerns associated with enclosing a single AC conductor in magnetic steel armour, though the full installation design still needs review.
What the Armour Does—and Does Not Do
The armour can provide protection against mechanical damage during handling and service, and may form part of the electrical fault-current path when the design and installation allow for it. It does not replace correct cable sizing, circuit protection, earthing, or suitable installation methods. The required armour construction and bonding arrangements should be confirmed by the project engineer. Buyers should avoid assuming that “armoured” automatically means suitable for direct burial or every harsh environment.
Typical Construction and Specification Options
AWA cables can vary in conductor material, insulation, sheath compound, core size, and armour design. Copper or aluminium conductors may be available depending on the required electrical performance, installation constraints, and project specification. XLPE insulation is commonly specified for power cables requiring a higher conductor operating-temperature rating, while PVC insulation is another option for applications that allow it. These are typical options, not a guarantee that every combination is available in every voltage or market.
| Specification item | What to confirm | Why it matters |
|---|---|---|
| Voltage rating | System voltage and required cable designation, such as 0.6/1 kV where applicable | Ensures the cable is specified for the electrical system |
| Conductor | Copper or aluminium, cross-sectional area, and conductor class | Affects current capacity, termination, and installation considerations |
| Insulation | Material, thickness, and required operating-temperature rating | Must suit the design conditions and governing standard |
| Armour and outer sheath | AWA wire construction, sheath material, colour, and environmental requirements | Supports mechanical and environmental suitability |
| Compliance documents | Applicable standard, inspection scope, and requested documentation | Helps verify that the supplied construction matches the purchase specification |
Temperature limits depend on the insulation system and the applicable product standard. For example, 90°C is a commonly specified maximum conductor operating temperature for XLPE-insulated cable, while 70°C is commonly associated with PVC-insulated cable; confirm the actual limits in the selected cable’s datasheet and standard. These figures are not a substitute for checking installation conditions, ambient temperature, grouping, or the cable’s current-carrying capacity. Ask the supplier to provide the technical data for the exact construction under consideration.

Applications and Cable-Type Matching
Low-voltage AWA cable may be considered for single-core power feeders, industrial distribution, and infrastructure or building services where the design calls for armoured cable. Its suitability depends on route conditions, electrical loading, exposure, installation method, and local rules. For a single-core AC circuit, the non-magnetic armour material can be an important design consideration. For multicore circuits, steel wire armour is often considered, but the project specification—not a general rule—should determine the correct cable type.
When to Compare AWA with Other Options
Compare AWA with unarmoured cable where mechanical protection is not required or is provided by conduit or another system. Compare it with steel wire armour when evaluating multicore constructions or other project-specific mechanical requirements. The right choice depends on the circuit arrangement, magnetic considerations, fault protection, environment, and installation method. Where cables pass through ducts, trays, or buried routes, confirm that the selected design is approved for those conditions.
A Practical Selection Framework
- Define the electrical duty. Record system voltage, load, installation length, expected fault conditions, and any starting or load variation relevant to cable sizing. Have a qualified designer verify conductor size and protective-device coordination.
- Confirm the cable configuration. State whether the requirement is single-core or multicore, copper or aluminium conductor, and the required number and size of conductors. Check that AWA is appropriate for that configuration.
- Describe the installation route. Identify whether the cable will be installed indoors, outdoors, in ducts, on trays, or underground, as applicable. Include exposure to moisture, chemicals, sunlight, temperature variation, and mechanical risks.
- Specify materials and standards. Identify the insulation and sheath materials, voltage rating, required standard, and any project-specific construction or documentation requirements. Do not rely on a generic product name if the project needs a defined build.
- Review termination and installation needs. Confirm compatible glands, lugs, bending space, armour bonding, and installation procedures with the project team. These details affect safe, compliant installation and should be resolved before ordering.
- Request technical confirmation. Send the supplier the completed specification and ask for a datasheet, construction details, applicable test documentation, and a clear statement of any deviations. Compare the offered product line by line with the approved requirement.
Pricing, MOQ, and Lead-Time Factors
The price of AWA cable depends on factors such as conductor metal and cross-sectional area, insulation and sheath materials, armour construction, order length, and requested documentation or packaging. Copper and aluminium options can differ in material cost and installation requirements, so compare complete project suitability rather than unit price alone. Minimum order quantities and production or dispatch lead times vary with the construction, quantity, and supplier schedule. Ask for a quotation based on the exact specification, delivery destination, required quantity, and target delivery date.
Supplier Evaluation Checklist
- Can the supplier confirm the proposed cable construction against your voltage, core, conductor, insulation, armour, and sheath requirements?
- Does the quotation identify the applicable standard and clearly state any exclusions or deviations?
- Can the supplier provide relevant technical data and the documentation required for your project review?
- Are packaging, cable length tolerances, marking, delivery terms, and order quantity clearly stated?
- Can the supplier explain how customization requests affect feasibility, price, and delivery timing?
