- 35 kV remotely-operated switch gearbox

Ideal for both urban and rural settings, a highline power substation replaces the need for traditional generators by connecting the rig directly to the regional power grid.
The result is dramatic fuel savings and significant reduction in generator noise and odor. In addition, the substation enables limited refueling and reduced truck traffic.
Best of all, the highline power substation requires only a negligible change to your rig footprint, minimal integration time, and zero sacrifice in rig performance.
