Temperature coefficient of screen material

Values for temperature coefficient of screen per K at 20$^{\circ}$C. are taken from standard IEC 60287-1-1 Ed.2.1 where available and from standard technical handbooks for the others.

Value for Aldrey (AL3) is taken from diploma thesis 'Quantifying the effect of time and temperature on the mechanical behaviour of Aldrey overhead line conductors' by M. Frigerio, 2016.
