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).
