Switchyard design

We design high-voltage switchyards for large manufacturing plants, from 110 kV to 230 kV, in both air-insulated (AIS) and gas-insulated (GIS) configurations.

What we deliver

• Switchyard single-line diagrams and equipment layouts for AIS and GIS
• Power transformer sizing and selection, up to 2 × 80 MVA
• Substation earthing design and lightning protection
• HV/LV cable routing, cable trench and tray layouts
• Specifications and data sheets for HV switchgear, transformers and protection panels
• Inspection and routine-test witnessing of HV equipment at manufacturers’ works
• Coordination with CEIG/CEA for drawing approval and the safety certificate
