Aluminum Conductor Steel Reinforced (ACSR) cables are a type of electrical conductor used primarily in overhead power transmission and distribution systems. They consist of a core made of steel strands for strength, surrounded by layers of aluminum strands that provide excellent conductivity. This construction allows ACSR cables to support high voltage transmission while being lightweight and resistant to corrosion.
| Material | Aluminum and steel |
| Conductor construction | Steel core with aluminum strands |
| Typical diameter range | 6 mm to 50 mm |
| Current carrying capacity | Varies based on size and installation conditions |
| Standard grades | AA-1350 aluminum, galvanized steel |
| Breaking strength | Varies by size, typically 10 kN to 200 kN |
When selecting ACSR cables, buyers should consider the specific electrical load requirements, environmental conditions, and installation methods. It's important to specify the conductor size, steel core configuration, and any necessary certifications for safety and performance standards. Quantities should reflect project needs, factoring in potential future expansions.
