EDS per sub-conductor (kN)

25% RTS = 22.5 kN — Where to find EDS?

EDS = Every-Day Stress — sustained tension at 15°C still air (kN)

Sources:

① Conductor catalog → find RTS (Rated Tensile Strength) → EDS = RTS × 0.25

② TEİAŞ Technical Specs / Project Criteria → EDS range: 25–33% RTS @ 15°C still air

③ Sag-tension software output (PLS-CADD, SAG10, etc.) → read 15°C EDA tension

↺ button auto-fills RTS × 25% as a conservative starting point
