Abstract
A low balanced reactance delta closure for a three phase electric arc furnace has delta connected tubular coil collectors mounted close to the transformer. Triangulated tubular phase conductors project through the wall of a closed transformer vault connecting to the collectors inside the vault and to flexible cable terminal heads, spaced for triangulation of the suspended cables, outside the vault. In each phase liquid coolant from an inlet connection outside the vault flows through an inlet passageway inside the tubular conductor, through passageways inside the tubular collector, back through the outlet passageway inside the tubular conductor and to an outlet connection outside the vault.
