FAMILY · FLYER
Transforms power between voltage levels.
Compact secondary substation, transformer package, MV / LV transformation system.
Known transformation boundary, repeatable transformer + protection arrangement, factory-assembled, reduced site coordination.
Indicative block diagram
Use when
Voltage conversion has to be compact, repeatable, and easier to commission.
Known boundary
Transformer, protection, MV/LV interface, ventilation, service access.
Operating value
Predictable conversion behaviour and clearer maintenance context.
