AERO-Z
New-generation conductor with Z-shaped wires in the outer layers
AAACZ / AACSRZ / AERO-Z are new-generation conductors with Z-shaped wires in the outer layers. The Z-profile ensures a tight fit between adjacent wires, which gives a smooth outer surface, a smaller diameter for the same cross-section and significant operational advantages: reduced sag, losses, vibration and ice accretion. Designation breakdown: AAACZ – All-Aluminium-Alloy Conductor Z-shape (aluminium alloy 6201 only), AACSRZ – Aluminium-Conductor Steel-Reinforced Z-shape (with a steel core).

AERO-Z is a modern conductor design with Z-shaped (trapezoidal profile) wires in the outer layers. The Z-profile sets these conductors fundamentally apart from classic AS conductors with round wires – this is a truly new generation of overhead line conductors.
Main advantages vs AS:
Used for the construction of new overhead lines with higher reliability requirements and for the reconstruction of existing lines – a Z-conductor makes it possible to increase transmission capacity without replacing the towers. Particularly effective in areas with wind and ice loads.
Core (for AACSRZ)
Galvanised (aluminium-clad) steel wires. Carries the mechanical load.
Outer Z-shaped layers
Shaped wires in the form of the letter Z made of aluminium alloy 6201 (heat-resistant, high-strength). The Z-profile gives a tight fit between the wires: the outer surface is smooth and internal voids are minimal.
Advantages of the Z-design
Smaller outer diameter for the same cross-section → lower wind load, less sag. Smooth surface → less ice accretion, early ice shedding. Self-damping of oscillations (vibration damping). Wires do not unravel if broken.
