Normal Span (M) =400

Notes - 1) All the derived Sag for the spans in stringing chart are in Meters

2) All the derived Tension are in Kgs

3) The Tension of the section of the Trans. line is based on the Equivalent Span of the section.

4) The Tension of the Conductor & Ground wire of section having Eq. Span less than Normal Span

are derived from the working condition specified in Column "Normal Span"
