# Connecting power lines around corners

I am working on a model city.

Suppose I have utility poles A, B and C (brown) that go around a sharp corner. Looking from above, how do I connect the poles with power lines (gray, solid)?

Are the crossarms of utility pole B rotated correctly with respect to the direction of the lines? Do the crossarms of pole B the correct length, or do they need to be longer than normal? Are there any other problems I should keep in mind?

Thanks.

You can easily see that the wires don't allign(parallel) with the dotted line which would be the line they should follow to maintain the same mutual distance. To calculate the widht the mast should have, you can take the width of the first mast, and divide that by $cos(\alpha)$ where $\alpha$ is half the angle the middle mast makes in degrees.
