Electrical Constants and Relative Capabilities of Bundled-Conductor Transmission Lines

The electrical characteristics of bundled-conductor transmission lines are analyzed in terms of the transmission capability of bundled-conductor versus single-conductor lines. The results of the analysis are presented in the form of several graphs as well as extensive tabulations of bundled-conductor transmission line constants (inductive and capacitive reactances, surge impedances, and surge impedance factors) as a function of conductor size, bundled-conductor or intragroup spacing, number of conductors per phase, and phase separation. The range of analysis is such that transmission voltage classes between 69 kv and 700 kv are considered.
