In which areas is AAC the preferred conductor for substation equipment connections?

The preferred use of Aluminum Alloy Conductors (AAC) in coastal areas is primarily due to their excellent corrosion resistance when exposed to saltwater environments. Coastal regions often confront harsh conditions that can significantly degrade other types of conductors, particularly those made from materials that are more susceptible to corrosion. The unique combination of aluminum's lightweight properties and its resistance to corrosion makes AAC an ideal choice for connections in substation equipment located in such areas.

In coastal settings, using AAC helps reduce maintenance costs and prolongs the lifespan of the conductors, which is critical for ensuring reliable electricity distribution. Other factors, such as weight and thermal characteristics, also contribute to AAC's advantages, making it favorable for installations that need to weather the specifics of coastal climates. These attributes play an essential role in the decision-making process regarding conductor selection in these environments.
