Double-channel bus forces and inductance

WHEN ARRANGED PROPERLY, channel conductors possess certain desirable electrical and mechanical characteristics. Thus, they can be arranged so that the cross section of the resulting bus approaches Arnold´s equal inductance cross sections¹ for which geometry the skin and proximity effects are reduced to a minimum. Channel conductors have considerable mechanical rigidity with which to withstand short-circuit forces. Their shape enables an open construction which simplifies ventilation and heat-dissipation problems.
