Pole line should not be designed to exceed what strength percentage?

The key idea is to use only a portion of the pole’s strength as the working load to keep a safety margin for real-world conditions. In pole line design, you should not push the pole beyond about sixty percent of its rated or tested strength. This leaves reserve capacity for peak wind gusts, ice loads, dynamic effects, aging, moisture, and potential damage over time, helping prevent sudden failure and allowing for maintenance or replacement as needed. Higher utilization (like seventy or seventy-five percent) reduces that safety margin too much, while fifty percent would be more conservative than typically necessary for balance between safety and cost.
