PRODUCT PREVIEW
Transformers
Project-specific power transformation
Wafr Packaged Unit Substations provide an integrated, factory-assembled solution combining medium-voltage switching, transformer and low-voltage distribution equipment within a coordinated outdoor enclosure.
Designed for Canadian environmental and electrical requirements, Wafr packaged substations reduce field installation time and simplify coordination between medium-voltage equipment, transformer protection and low-voltage distribution.
Each system is engineered according to project voltage, capacity, available fault current, environmental conditions and protection requirements.
