ACSR Bare Conductor Steel Reinforced 150mm Overhead BS215 Standard
Application
ACSR (Aluminum Conductor Steel Reinforced) is a composite overhead cable combining aluminum strands for conductivity and a steel core for strength. Its key applications include:
Overhead Power Transmission & Distribution
- High-Voltage Lines: Ideal for transmission towers (33kV to 500kV) due to high tensile strength.
- Long Spans: Used in river crossings, mountainous areas, and windy regions (resists sagging).
- Rural Grids: Cost-effective for medium-voltage distribution (11kV-33kV).
Advantage
High Strength-to-Weight Ratio: Steel core supports heavy loads without excessive sag.
Cost-Efficient: Aluminum provides conductivity at lower cost vs. pure copper.
Durable: Resists corrosion (galvanized steel core) and extreme weather.
Standards
ASTM B231 (US), IEC 61089 (International)
Core Types
Single Steel Core: For standard spans.
Multi-Strand Steel Core: Extra strength (e.g., ACSR "Drake" for heavy loads).
