To carry out a damping study of this kind, there are some parameters that SAPREM requires to the customer:
a) Line identification: country, name, voltage, etc.
b) Mechanical and dimensional characteristics of conductor.
c) Description of clamps and armour rods, if any.
d) Tensile load in the average span, without overload, at the average temperature in the coldest month of the year. When this tensile is not available, it must be provided enough data for its calculation, specially the above mentioned temperature or a logic approximation to it.
e) Minimum, average and maximum span length.
f) Orography, type of terrain and vegetation along the line. Eolical particularities.
g) Special spans: crossings of lakes, rivers, gully and steep riverbanks, spans over 700 m. Description of other particular characteristics.
