01 — HV/EHV Substations (33/66/110/132/220/400kV)

Our substation capability is structured for utility and industrial projects that require robust GIS, AIS, or hybrid configurations under demanding grid conditions. We support development phases from concept through detailed engineering and packaged procurement alignment, including transformer bays, circuit breakers, CT/VT interfaces, surge arresters, busbar arrangements, protection and control architecture, SCADA/IEC 61850 integration, auxiliary AC/DC systems, and earthing. Civil interfaces are coordinated from early layout studies to constructability-ready documentation. System studies such as load-flow, short-circuit, and insulation coordination are integrated with SLD, GA, cable schedules, and BOQ outputs to support clear decision gates. This is positioned as capability for suitable projects, delivered through qualified networks, and not presented as a claim of completed jobs in every listed voltage class.
