African rural electrification and regional grid extension projects often connect newly built substations to distribution networks with different voltage standards. This dual voltage oil immersed distribution transformer is developed for utilities, government infrastructure contractors and EPC companies that require greater voltage adaptability during network development.

The transformer can be configured around commonly encountered African distribution voltages such as 11kV, 22kV and 33kV, with the secondary side designed for local low-voltage distribution networks.

Project Advantages

Dual HV voltage capability for network expansion and voltage conversion requirements
Compact oil-immersed structure for substation installation
Suitable for pole-mounted, ground-mounted or compact substation configurations depending on capacity
High-voltage insulation system adapted to medium-voltage distribution networks
Optional off-circuit tap changer for local voltage adjustment
Designed and manufactured according to project-specific technical specifications
