132 Tower Data

1) The document outlines tower spotting requirements for different types of towers (K, L, M) used for a 132kV DC transmission line. 2) It specifies limitations for the vertical load of individual spans, normal spans, deviations from spans, wind spans, vertical load limitations for ground wires and conductors, permissible sums of adjacent spans based on deviation angles, and design longitudinal tensions under different conditions. 3) The requirements aim to ensure tower spotting results in safe and stable placement of towers along the transmission line route within specified technical parameters.
