Pin or strain for uplift?
The profiler can indicate when there might be a problem with uplift on a pole. There are a few ways you can compensate for uplift:
- reduce tension in the conductor
- install a bigger pole
- replace a pin construction with a strain construction
Many utilities indicate they permit zero uplift so one of these solutions will be required.
When can you still use a pin construction if uplift is indicated? The issue is avoiding strain on the tie wires. Your utility’s design manual may give guidance.
