However, here are some options you could consider, depending on the context:
* A line of poles: This is the most straightforward and descriptive option.
* A row of poles: Similar to "line," this emphasizes their arrangement.
* A stand of poles: This implies a group of poles standing together, perhaps in a particular location.
* A grid of poles: This is appropriate if the poles are part of a larger power grid system.
Ultimately, the best choice will depend on the specific situation and the impression you want to create.
