ACSR-Aluminum Conductor Steel Reinforced

Aluminium Conductor Steel Reinforced (ACSR) consists of a solid or stranded steel core in the centre, and concentrically stranded aluminum wires in external layers. 

Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.

APPLICATION

 

ACSR is used as bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.

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).

3. Mechanical Characteristics (Core Advantage vs AAC/AAAC)

1. Ultra-high tensile strength: Steel core tensile strength: 1100–1800 MPa; total rated breaking strength 20–250 kN. Supports extra-long spans (over 400m), river-crossing and mountain valley lines with fewer supporting towers.
2. Low sag performance: Composite linear expansion coefficient (between aluminum 23×10⁻⁶ /℃ and steel 11.5×10⁻⁶ /℃) far lower than pure aluminum conductors; much smaller thermal sag under full load, improving line safety clearance.
3. Excellent strength-to-weight ratio: Aluminum low density (2.703 g/cm³) + high-strength steel core: lighter weight than pure steel cable, stronger than full-aluminum cable of same weight.
4. Strong environmental load resistance: Resists heavy ice coating, strong wind vibration; standard galvanization provides basic anti-corrosion for inland areas.
5. Self-damping property: Small relative sliding between aluminum and steel strands suppresses aeolian vibration, less fatigue breakage risk.

4. Advantages

1. Balanced electrical conductivity & mechanical strength, mature universal design for global power grids.
2. Cost-effective: lower price than AAAC/ACSS, complete global supply chain.
3. Wide application coverage: 10kV distribution lines to 500kV/750kV ultra-high voltage transmission lines.
4. Easy maintenance, fully recyclable aluminum & steel materials.

5. Limitations

1. Maximum continuous working temperature only ~90℃, cannot overload for long periods.
2. Ordinary galvanized steel core suffers accelerated corrosion in coastal salt fog, industrial acid gas environments (needs aluminum-clad steel core upgrade).
3. Proximity effect exists in multi-circuit parallel lines, slightly increasing AC loss.

6. Main Application Scenarios

- General overhead high/extra-high voltage transmission lines
- Long-span river-crossing, mountain-crossing overhead lines
- Overhead ground wires (shield wires) for transmission towers
- Medium-voltage rural & urban distribution overhead lines
