FAQ
Q. What is an AAC bare conductor?
A. AAC (All-Aluminum Conductor) is an overhead power line conductor made entirely of aluminum with no steel or other metal reinforcement, offering lightweight and corrosion-resistant properties.
Q. What are the primary applications of AAC bare conductors?
A. AAC is commonly used in medium-voltage distribution networks (1–35 kV) and urban/suburban power transmission due to its cost-effectiveness and ease of installation.
Q. What are the advantages of AAC over copper conductors?
A. Lower cost, lighter weight, and better corrosion resistance in humid or coastal environments. However, copper has higher conductivity.
Q. Does AAC require special installation techniques?
A. Yes, it needs proper tensioning and supports due to its lower tensile strength compared to ACSR. Sag must be carefully calculated to avoid overstretching.
Q. How does weather affect AAC performance?
A. AAC resists corrosion but may experience thermal expansion. Ice or wind loads require additional support structures.
Q. What maintenance does AAC need?
A. Regular inspections for sag, corrosion, and hardware integrity. Cleaning vegetation near lines is essential to prevent damage.
Q. Is AAC environmentally friendly?
A. Yes, as aluminum is 100% recyclable. AAC’s lifecycle carbon footprint is lower than steel-reinforced alternatives.
