Compact Sub-Station (CSS/PSS)

Our Compact Substations (CSS) — also known as Packaged Substations — provide a fully integrated solution for power distribution up to 33 kV. Each unit houses a medium-voltage switchgear (VCB / LBS / RMU), a distribution transformer, and a low-voltage panel (PCC) in a compact, factory-built, and fully enclosed enclosure.
They are ideal for outdoor installations requiring minimum space, faster commissioning, and enhanced safety.
