Equivalent span length and sag
- Estimated study time: 86 minutes
Study resources
- Equivalent Span Length & Sag (Article) — Covers catenary vs parabolic sag approximation, equivalent span length concept and the effect of temperature/ice/wind on conductor weight per unit length. Practical engineering reference.
- Sag & Tension Calculation (Article) — Covers the standard practice of keeping conductor tension below 50% of UTS (safety factor = 2). Derives sag formula for equal-level supports with clear phasor diagrams.
