Specific electrical resistivity of screen material

Values for specific electrical resistivity of screen material at 20°C. are taken from standard IEC 60287-1-1 Ed.2.1 where available and from standard technical handbooks for the others. The standard provides a different value of aluminium conductor and sheaths and armour. We use the same value for screen as for sheath.

Value for Aldrey (AL3) is taken from EN 50183, the value given by a manufacturer was 3.33e-8.
