ACSS
Used for overhead distribution and transmission lines, new line applications that require high emergency loading, and where vibration is a problem. ACSS operates continuously at high temperatures up to 250°C full strength. Although similar to standard ACSR, ACSS sags less and is self-damping during installation. It also carries a higher current than standard ACSR.
Construction
What it's built from
- Construction
- Aluminum alloy 1350 wires, concentrically stranded around a steel core.
- Finish
- Non-Specular finish available on request.
