WebThe sag sections are normally not longer than 4 miles. Sag sections must have control spans. The control spans will be used to measure the sag for each sag section. If the control spans are properly sagged, the conductors in the sag section should all be at the proper tension. The control spans should be approximately the length of the ruling span.
