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. Each module below is specified to your project. Tell us your requirement (e.g. ring-network feed + 800 kVA + tropical rating) and we build to it.

Section 1

HV Switching

Four-position load switch + backup & plug-in fuses.

Section 2

Transformer (in oil)

Sealed oil-immersed core, oil = insulation & arc-quench.

Section 3

LV Side

Metering, distribution and compensation to spec.
