neglected, because distances from overhead conductors to ground are always greater than distances
among conductors.
13.6 Characteristics of Overhead Conductors
Tables 13.2aand 13.2bpresent typical values of resistance, inductive reactance and capacitance react-
ance, per unit length, of ACSR conductors. The size of the conductors (cross-section area) is specified in
square millimeters and kcmil, where a cmil is the cross-section area of a circular conductor with a
diameter of 1=1000 in. The tables include also the approximate current-carrying capacity of the
conductors assuming 60 Hz, wind speed of 1.4 mi=h, and conductor and air temperatures of 75 8 C
and 25 8 C, respectively. Tables 13.3a and 13.3b present the corresponding characteristics of AACs.
