Steel Supported Conductors

These conductors consist of a high strength steel core with one or more layers of Annealed Aluminium wires (Al 1350-0). Steel core wires are protected from corrosion at high temperature by special zinc - 5% aluminium alloy coating. This allows:

• Thermal expansion linked to the high strength steel core which limits the sag increase due to temperature increase
• The use of high tensile steel wires
• Continuous operating temperatures up to 200°C with no long term creep
• Low losses due to the high conductivity of Annealed Aluminium
• Mechanical properties comparable with AAAC and ACSR conductors
• Reduced aeolean vibration due to low mechanical load on the Aluminium wires

ACSS conductors are suitable to replace AAAC and ACSR conductors in short, middle and long spans lengths in all the orographic conditions (plain, hill or mountains).
