APPLICATION

ACSR Merlin Conductor is suitable for use in all practical spans on wood poles, transmission towers, and other structures. Applications range from long, extra high voltage (EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises.ACSR (aluminum conductor steel reinforced) has a long service record because of its economy, dependability, and strength to weight ratio.

The combined light weight and high conductivity of aluminum with strength of the steel core enables higher tensions, less sag, and longer spans than any alternative.

CHARACTERISTICS

1. Structural Characteristics

1. Concentric stranding structure: Central steel core (1/7/19 galvanized steel strands) + multi-layer outer aluminum strands; adjustable aluminum-to-steel area ratio to balance conductivity and tensile strength.
2. Customizable steel core types:
- Standard galvanized steel (GA2): general inland transmission lines
- High-strength galvanized steel (GA5): long-span, heavy ice/wind load sections
- Al-clad steel / Zn-5Al alloy coated steel: coastal, high-corrosion environment anti-rust upgrade
3. Flexible stranded design: Good bending performance, easy transportation, stringing and installation on transmission towers.

2. Electrical Characteristics

1. High conductivity: Aluminum conductivity ≈61% IACS; almost all power flows through outer aluminum layers, steel core barely conducts electricity.
2. Controllable DC resistance: Typical DC resistance (20℃): 0.02~0.40 Ω/km, determined by aluminum cross-section and stranding structure.
3. Skin effect advantage: At AC high frequency, current concentrates on conductor surface (aluminum layer), effectively avoiding power loss from steel core’s high resistivity.
4. Low corona loss: Larger overall diameter vs all-aluminum conductor (AAC) of equal conductive area, reduces corona discharge and radio interference for HV/EHV lines.
5. Operating temperature limit: Continuous allowable temperature: 75–90℃. Exceeding this will anneal hard-drawn aluminum, permanently reducing tensile strength; high-temperature scenarios adopt ACSS instead.
6. Typical ampacity range: 200–1500 A (depends on cross-section, wind speed, ambient temperature).
