Main Substation System
High-voltage intake substations that step 66 kV supply down to 33 kV or 11 kV for utility networks, infrastructure, and major industrial power requirements.
Defined project scope
One coordinated system, not disconnected packages
Power Tagun coordinates technical decisions, equipment interfaces, site delivery, testing, and handover around the approved system requirement.
System studies and single-line design
Transformer and switchgear specification
Protection, control, and metering coordination
Installation, testing, and energisation support

- 03
Installation
Coordinate site interfaces, installation quality, and construction readiness.
- 04
Testing
Verify protection, control, equipment, and system performance before energisation.
- 05
Commissioning
Control handover, energisation, and project records.
