ACSR/AW-TW type of overhead conductors utilize both advantages of trapezoidal aluminium wires and aluminium-clad steel core. The utilization of compact trapezoidal strands introduces a significant increase of approximately 20% in the aluminium part's cross-sectional area of the conductor. This, in turn, leads to a reduction in electrical resistance and energy loss. Implementing an aluminium-clad steel core instead of galvanized steel core, results in a noteworthy 5% decrease in electrical resistance and transmission line loss under equivalent loading conditions.

Conventional aluminium wires are typically characterized by a circular cross-section. However, an innovative alternative involves employing trapezoidal-shaped aluminium wires (TW) in lieu of circular wires, while maintaining the same aluminium content. By adopting this approach, the strength-to-weight ratio remains constant, but the integration of trapezoidal aluminium wires results in a more condensed overall conductor configuration. As a result, the overall diameter experiences a reduction of approximately 10% to 15%.
ACSR/AW-TW advantages over typical ACSR conductors:
- Reduced Drag Force and Ice Accumulation
- Extended Span Lengths
- Improved Electrical Performance
- Extended Lifespan and Reduced Resistance
