ACAR Bare Conductor Aluminum Conductor Aluminum Alloy Reinforced Bare Overhead Conductors

APPLICATION

ACAR (Aluminum Conductor Alloy Reinforced) bare conductors are widely used in:

• ‌High-voltage transmission lines‌ (e.g., overhead power grids) due to their lightweight and cost-effectiveness compared to copper‌.
• ‌Rural electrification projects‌ where aluminum’s lower material cost offsets installation challenges‌.
• ‌Renewable energy systems‌ (e.g., wind/solar farms) for long-distance power distribution‌

CONSUTRUCTION

ACAR (Aluminum Conductor Alloy Reinforced) bare conductor is a composite stranded wire primarily composed of ‌high-purity aluminum alloy strands‌ and ‌reinforcing steel core wires‌. The structure features:

• ‌Outer Layer‌: Multiple layers of aluminum alloy strands (typically 6101 or 6201 alloy) arranged in concentric layers, providing high conductivity and corrosion resistance.
• ‌Core‌: A central steel core (usually galvanized steel) for mechanical strength, ensuring tensile resistance against wind and ice loads.
• ‌Layering‌: The aluminum strands are helically wound around the steel core with a ‌specific lay length ratio‌ (e.g., 6:1 or 8:1) to balance flexibility and structural integrity.

CHARACTERISTIC

• ‌Conductivity‌: Aluminum alloy strands achieve ‌53-61% IACS‌ (International Annealed Copper Standard), optimized for power transmission efficiency.
• ‌Tensile Strength‌: The steel core contributes to a ‌minimum breaking load‌ of 20-40% higher than pure aluminum conductors of the same diameter.
• ‌Diameter Ratio‌: The steel core diameter is typically ‌1/3 to 1/2‌ of the total conductor diameter, ensuring optimal weight-to-strength balance.

FAQ

What is ACAR conductor made of?‌
ACAR (Aluminum Conductor Alloy Reinforced) consists of high-strength aluminum alloy strands with a steel core for enhanced mechanical performance.
‌What are the advantages of ACAR over AAC conductors?‌
ACAR offers higher tensile strength (30-40% greater than AAC) while maintaining good conductivity, making it ideal for long-span applications.
‌Does ACAR conductor comply with international standards?‌
Yes, it meets BS EN 50182:2001 (European standard) and ASTM B230 (U.S. standard) for alloy composition and mechanical properties.
‌What temperature range can ACAR conductors operate in?‌
Standard ACAR operates between -40°C to +90°C, with optional coatings for extreme environments.
‌How is ACAR conductor installed?‌
It uses standard tensioning tools for overhead lines, with recommended sag tables provided in BS EN 50182.
‌What is the typical lifespan of ACAR conductors?‌
Designed for 40+ years, lifespan depends on environmental factors (e.g., coastal areas may require galvanized steel cores).
‌Can ACAR be used for underground applications?‌
No, it is exclusively for overhead transmission/distribution lines. Underground applications require insulated cables.
‌How does ACAR compare to ACSR conductors?‌
ACAR has a higher aluminum-to-steel ratio than ACSR, offering better conductivity but slightly lower strength.
