Configure Your Substation

An American-type (pad-mounted) substation is a single compact assembly: the HV switching, fuse protection and transformer share one oil-filled tank, with the oil serving as both insulation and arc-quenching medium. Select the functions and supply arrangement your project requires, then send us the single-line diagram for technical confirmation.
