AC and DC rig electrical equipment

Everything electrical that goes into operating a rig, AC or DC. SCR/DC systems remain EI's deepest specialty, and we also source the drives, controls, power distribution, motor control, protection, and support hardware used on AC-powered super-spec rigs.

AC Drives & VFD Systems

Low- and medium-voltage drives for drawworks, mud pumps, top drives, rotary systems, and rig auxiliaries, current through long-obsolete.
