As veryone else has suggested, the clone tool or healing brush will allow
you to *paint* them out of the picture.

However, if you have another reason for wanting to select the power lines,
try this.
Copy the image into a new layer and convert the whole thing to grayscale.
Now go into images>adjustments>levels and constrict the white and black
channels together to increase the contrast to the point where you're left
with a silhouette.
You can now use this silhouette layer, or selected parts of it as a layer
mask to pick out the relevant parts.
