Aluminum Wire & Aluminum Main Cable (Aluminium Wires)
What Is Aluminum Wire?
Aluminum wire is an electrical conductor made from aluminum, widely used for power distribution and transmission. It is lighter and more economical than copper for the same current-carrying capacity, which makes it especially popular for overhead lines and large feeder cables. Aluminum wire comes insulated for building use and bare for overhead and grounding work.
Low-Voltage Aluminum Wire
Insulated aluminum building wires such as THW-A, NAY, and AWV are rated 300–750 V and used to run main feeders and distribute power inside buildings, factories, and construction sites.
Medium-Voltage Aluminum Wire & Aerial Cables
SAC (spaced aerial cable) and similar XLPE-covered conductors are rated 1–36 kV for medium-voltage overhead distribution, offering safety and reliability on utility poles.
Bare Aluminum Conductors
Uninsulated conductors such as AAC (all-aluminum conductor) and ACSR (aluminum conductor steel-reinforced) are used for overhead transmission and distribution lines, where the steel core of ACSR adds tensile strength for long spans.
Advantages and Disadvantages of Aluminum Wire
Advantages: lighter weight, lower cost, and easier handling than copper for the same capacity — ideal for long overhead runs. Disadvantages: lower conductivity than copper (needing a larger cross-section for the same current), and connections require anti-oxidation compound and correct torque to stay reliable.
How to Buy Aluminum Wire at Contractor Prices
Choose wire that matches your system’s voltage, required current, and installation environment, and confirm it meets the appropriate TIS/IEC standard. Buying from a trusted wholesaler ensures consistent quality and the best price for your project.
How to Maintain Aluminum Wire
Inspect connections periodically, keep terminations clean and correctly torqued, and use anti-oxidation compound at joints to prevent resistance build-up. Well-maintained aluminum wiring gives long, reliable service.

Frequently Asked Questions About Aluminum Wire (FAQs)
What jobs is aluminum wire suited for?
It suits main feeders, long-distance runs, overhead-line work, and low-to-medium-voltage systems, thanks to its light weight, lower cost, and reduced structural load.
Is it safe to use aluminum wire instead of copper?
Yes, if you choose a cross-section 1–2 sizes larger than copper, use TIS-standard cable, and use connectors designed specifically for aluminum wire.
How should I choose aluminum wire for the job?
Consider the voltage level, environment, and installation type — for example, coastal areas should use AAAC, while residential zones are best served by SAC or PAC for safety.
How long does aluminum wire last?
Aluminum wire generally lasts more than 20–30 years if it is TIS-standard cable installed correctly to engineering practice.
What to look for when buying aluminum wire at contractor prices?
Choose TIS-standard cable with clear specs matched to the job, from an expert supplier who gives real technical advice. TETA INTERTRADE offers complete products and after-sales service, with contractor pricing based on your exact length and cross-section — controlling project costs and reducing on-site risk from the start.
