These conductors is composed by a high strength steel core with one or more layers of annealed aluminium wires (AA-1350). Steel core wires are protected from corrosion at high temperature by special zinc-aluminium alloy coating.
This conductor shall work at operating temperature up to 200°C.
The main point of this product family:
- Mechanical properties are compatible with AAAC and ACSR
- Low losses due to the high conductivity of annealed aluminium
- Limited variation on sag
