There are three primary types of aluminum conductors widely used in overhead transmission lines:

1. All-Aluminum Conductor (AAC): Made entirely of high-purity aluminum, AAC is lightweight and has good conductivity. It is typically used for short-span, low-voltage lines in urban areas or coastal regions where corrosion resistance is a key factor.

2. All-Aluminum Alloy Conductor (AAAC): Composed of an aluminum-magnesium-silicon alloy, AAAC offers a better strength-to-weight ratio and greater corrosion resistance than AAC. It is a great choice for medium-span lines in areas with corrosive atmospheres.

3. Aluminum Conductor Steel Reinforced (ACSR): This is the most prevalent type of conductor for high-voltage and long-distance transmission lines. It consists of multiple strands of aluminum wrapped around a central core of steel. The steel core provides the necessary mechanical strength to support the conductor over long spans, while the outer aluminum strands carry the current.

Our range of overhead transmission line equipment, including tension stringing machines and accessories, is designed to handle all these types of conductors effectively and safely.
