Primary Distribution Substation System
Primary distribution substations that step 33 kV supply down to 11 kV and feed the medium-voltage networks serving towns, industrial zones, and large developments.
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.
Load assessment and single-line design
Power transformer and 33 kV / 11 kV switchgear specification
Feeder protection, control, and metering coordination
Installation, testing, and energisation support
Typical equipment
