- Class AA conductors are usually used in overhead lines where high strength and low flexibility are required.

- Class A conductors are suitable for covering with weather-resistant materials or for bare applications where more flexibility than Class AA is needed.

- Class B conductors are designed for insulating with various materials or for more flexible applications than Class A.

- Class C and D conductors offer even more flexibility than Class B and are used where extreme bending is required.
