The choice of conductor for a 33kV line depends on factors like span length, environmental conditions, and required current-carrying capacity. The most common types are:

• ACSR (Aluminum Conductor Steel Reinforced): This is the most popular choice for 33kV lines. The steel core provides excellent tensile strength, allowing for longer spans between support structures. The outer aluminum strands offer high conductivity and are lightweight, making installation easier.

• AAAC (All Aluminum Alloy Conductor): Used in coastal or corrosive environments where galvanic corrosion between aluminum and steel is a concern. The aluminum alloy provides a good balance of strength and conductivity.

• AAC (All Aluminum Conductor): While it has lower tensile strength than ACSR, AAC is lightweight and highly resistant to corrosion. It is often used for shorter spans and in urban areas where supports are closer together.
