This guide provides a template to assist line design engineers in gathereing information and organizing it into a coherent design criteria document for use in the design of overhead electric power transmission lines, generally at voltages of 69 kV and higher. The guide will also be useful for the design of lower voltage lines.
This generic standard may be applied in all fields of electronics where equipment and installations are required to conform to a metric modular order. The choice of coordination dimensions for the mechanical structure for heights, widths, and depths lies within a homogeneous, metric, modular, three-dimensional grid as specified in IEC 917 (1988) [13]. Optimum conditions are thereby created for the application of computer-assisted methods throughout design and manufacturing, such as, for… read more instance, computer-assisted planning, development, manufacturing, testing, and installation. read less
