Product Introduction
ACSS Conductor Cable: Structured Overview
1. Definition and Composition
ACSS (Aluminum Conductor Steel Supported) is a concentric stranded composite conductor, composed of:
- Core: Galvanized steel strand (Grade A) that carries most or all mechanical loads.
- Outer Layers: One or more layers of annealed 1350-0 aluminum, providing high conductivity.
2. Standards Compliance
ACSS conductor cables adhere to the following industry standards:
| Standard Code |
|---|
| Q320623 AP 32 |
| IEC 62219 |
| ASTM B851 |
| ASTM B857 |
3. Technical Characteristics
Key properties and advantages of ACSS cables:
- High-Temperature Operation: Can operate continuously at temperatures up to 250°C without loss of strength.
- Sag Performance: Exhibits lower sag under electrical loads compared to similar ACSR conductors.
- Self-Damping Capability: If pre-stretched during installation, it can become self-damping.
- Creep Resistance: Final sag is not subject to long-term creep conditions of aluminum.
- Applications: Particularly useful in heavy conductivity applications requiring increased current, such as overhead transmission and distribution lines.
4. Notes and Specifications
