Aluminum Clad Steel Wire (ACS Wire)
Aluminum Clad Steel Wire (ACS Wire) consists of a high-strength steel core covered with a layer of high-conductivity aluminum that is metallurgically bonded to ensure long-lasting performance and reliable conductivity. The seamless aluminum coating forms a permanent bond with the steel core, maintaining its integrity during rewinding, stranding, and installation processes. Due to its excellent mechanical strength, corrosion resistance, and electrical properties, ACS Wire is widely used as an Overhead Ground Wire in power transmission and distribution networks. It is specifically designed for aerial power transmission lines, river crossings, telecommunication systems, and other utility infrastructure applications where durability and dependable performance are essential.

Aluminum Clad Steel Wire CONSTRUCTION
1. Conductor
Aluminum Clad Steel (“ACS”) wire consists of a central steel core with a layer of high conductivity aluminum extruded over it. The aluminum layer forms a seamless metallurgical bond with the steel core, ensuring permanent adhesion and stable performance during rewinding, stranding, and installation. This makes Aluminum Clad Steel Wire (ACS Wire) highly reliable for electrical and mechanical applications. Due to its excellent strength, conductivity, and corrosion resistance, ACS Wire is widely used as an Overhead Ground Wire in overhead power distribution systems. It is especially suitable for aerial power transmission lines, river crossings, and other critical infrastructure projects where durability and long service life are required.
Generally, the ACS Conductor is formed by the following construction:
