Which type of stranding is used for 8000 series aluminum feeder conductors?

The correct choice is compact stranding, which is specifically designed for 8000 series aluminum feeder conductors. This type of stranding offers several benefits that are particularly advantageous for feeder applications.

Compact stranding involves a layout where the individual aluminum wires are packed more closely together. This reduces the overall diameter of the conductor while maximizing the conductor's flexibility and minimizing its weight. As a result, compact stranded conductors can exhibit improved conductivity and mechanical strength compared to traditional or other types of stranding. This makes them ideal for installations where space is limited or where weight is a critical factor.

The design of compact stranding also helps in reducing the overall skin effect, allowing for better performance in AC applications. This design attribute makes compact stranding particularly effective for handling the current ranges typically found in feeder applications, where efficiency and reliability are paramount.

Other types of stranding, while used in various electrical applications, do not provide the same combination of benefits that are specifically suited for 8000 series aluminum feeder conductors.
