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.
