Aluminium Conductor Composite Core (ACCC) conductors are meticulously engineered to operate continuously at elevated temperatures of 180 °C, with the capacity to withstand emergency conditions of up to 200 °C for brief durations. In the construction of ACCC conductors, a composite core provides structural integrity, around which trapezoidal-shaped annealed 1350-O aluminium wires with exceptional electrical conductivity are meticulously arranged.
The innovative design capitalizes on the lightweight nature of the composite core, enabling the integration of more aluminium (configured in the trapezoidal cross-sectional shape) within the conductors. Remarkably, this augmentation in aluminium content does not surpass the weight of comparable ACSR and ACSS conductors with the same diameter. The trapezoidal annealed aluminium wires, coupled with their enhanced electrical conductivity, contribute to the ACCC conductors' superior performance and capacity.
The amplified electrical conductivity of ACCC conductors, stemming from the annealed and trapezoidal-shaped aluminium wires, translates to a substantially increased electrical current transmission capability. For instance, the electrical current transmission capacity of an ACCC conductor can be up to twice that of an equivalent ACSR conductor.
Moreover, the ACCC conductor's low coefficient of linear expansion yields a diminished reliance on temperature-induced variations in length. This attribute culminates in reduced sag, contributing to the conductor's resilience under changing conditions. Notably, ACCC conductors are classified as part of the High-Temperature-Low-Sag conductor category, embodying their exceptional suitability for demanding operational environments.
ACCC conductors offer the following benefits:
- Impressive strength-to-weight ratio
- Enhanced electrical current transmission capacity
- Reduced sag and potential for longer spans to minimize tower count
- Diminished conductor diameter, minimizing impact of ice, snow, and aerodynamic forces
- Well-suited for polluted and coastal environments
