Answer: The choice of conductor material is a balance of electrical conductivity, mechanical strength, weight, and cost. While copper was historically used, aluminum is now the predominant material due to its lighter weight and lower cost. The most common types of conductors include:

• AAC (All-Aluminum Conductor): Made of aluminum strands, it is lightweight and highly corrosion-resistant, making it suitable for coastal areas and shorter spans.

• ACSR (Aluminum Conductor Steel Reinforced): This is the most widely used conductor for overhead transmission lines. It consists of a central core of high-strength galvanized steel strands surrounded by layers of aluminum strands. The steel core provides the necessary mechanical strength for long spans, while the outer aluminum layers carry the electrical current.

• AAAC (All-Aluminum Alloy Conductor): This conductor is made from a high-strength aluminum-magnesium-silicon alloy, offering better mechanical strength than AAC and good corrosion resistance, providing a middle ground between AAC and ACSR.

We manufacture and supply a full range of equipment and tools for the installation and maintenance of these different types of conductors, from stringing equipment to compression tools.
