ACS, or Aluminium-Cladded Steel wire, is a conductor composed of an inner steel core and aluminium coating. Aluminium clad steel wire (ACS) wires are bimetallic wire with aluminium covered lines, covering the steel core continuously and evenly.
Send InquiryAluminium-clad steel (ACS) wire is superior to galvanized or aluminized steel in every way.

The Director’s Insight on Aluminum-Clad Steel (ACS) Wire in Overhead Transmission Lines
Aluminium-Cladded Steel wire is generally used for long-term transmission lines in coastal and island areas, other tropical and subtropical regions, dense fog regions, and highly polluted areas where corrosion resistance is required. As an alternative to galvanized steel wire, ACS wire is a game-changer due to its strength and corrosion resistance. ACS wires have been used in a variety of applications, including –
Major Applications : Armor Wire of OPGW, The Steel Core Of Conductor ACSR/AW, Messenger Wires.
Other Applications: Guy Wires, Web Application, Barbed Wire, Grape Vineyards.
ACS is two metals bonded together in strong steel core with an aluminum coating. The bonding’s metallurgical, not mechanical. That means the layers can’t separate. We create it through hot extrusion, fusing aluminum to steel at the molecular level. It’s fundamentally different from just coating steel with zinc or aluminum. We’re creating an integrated material where the two metals become one unit.
ACS gives you aluminum-level corrosion protection, which absolutely demolishes galvanized steel in harsh environments. In coastal areas, humid tropical zones, or near industrial pollution, galvanized ground wires corrode significantly in 15-20 years. ACS wires in the exact same conditions? 40+ years easily. Plus you eliminate galvanic corrosion that’s the electrochemical decay that happens when different metals touch in humid conditions. ACS is one material, so no electrochemical issues. In coastal India, ACS is a no-brainer.
ACS is monolithic – aluminum and steel bonded as one permanent unit. ACSR (Aluminum Conductor Steel Reinforced) wraps separate aluminum strands around a steel core. They’re mechanically combined but stay distinct materials. In humid or salty environments, that interface becomes a corrosion hotspot because of electrochemical action. ACS eliminates that weakness entirely. It’s a superior material, especially for challenging environments.
ACS is the core material in ACSR/AW conductors. It’s the outer layer in OPGW cable. And it’s the primary ground wire on transmission lines anywhere corrosion is a real concern of coastal routes, long river crossings, tropical zones, pollution-heavy industrial areas. Anywhere engineers think ‘we need this to last 40+ years in a harsh environment,’ ACS becomes the default choice. Once people understand the material, they prefer it over cheaper alternatives.
We’ve got 14 high-speed production lines at Kadi producing ACS wire at ultra-high tensile strengths. We can support 8,000+ kilometers of OPGW production annually. Quality-wise? We have a 500 kilonewton Universal Testing Machine and video measuring equipment checking to 2-micron accuracy. That precision capability is rare. Most cable manufacturers can’t match it. We maintain tolerances that ensure perfect fit in OPGW applications.
IEC, ASTM, ANSI, GOST, whatever the customer needs. That multi-standard capability is why we export globally. Customers in different countries have different procurement specs, and we meet all of them. Combined with our testing infrastructure and consistent quality, that’s why we’re credible internationally. We don’t just manufacture, we manufacture to exacting standards that customers can depend on.
