Abstract
At present, the power transmission capacity of a.c.
lines worldwide is close to its minimum value. To
increase it, the conductor surface area must be
increased, which is achieved by increasing the nUlllber
of subccnductors per phase and optimizing their
space arrangement. In so doing, phase-to-phase
spacing may be substantially decreased, which is, the
basic for creating compact lines with increased
natural capacity.
