What is a YB-12 prefabricated substation?
It integrates medium-voltage switchgear, a transformer and low-voltage distribution equipment inside a coordinated outdoor enclosure.
What transformer capacity is available?
Project configurations are available up to 3150kVA within the confirmed YB-12 design scope.
Can it use an oil-immersed or dry-type transformer?
Both arrangements can be evaluated according to capacity, loss requirements, fire-safety rules, ventilation and the project specification.
Which MV switchgear can be installed?
The medium-voltage compartment can be configured with suitable RMU or switchgear according to the system voltage, SLD, protection philosophy and available space.
How is the LV section configured?
Incoming, outgoing, metering, protection and reactive-power compensation are selected against the load schedule and project requirements.
Are enclosure dimensions fixed?
No. Overall dimensions depend on transformer capacity, compartment arrangement, access, ventilation, cable entry and local project requirements.
What is needed for quotation?
Please send the SLD, transformer schedule, primary and secondary voltage, capacity, vector group, impedance, feeder list and site conditions.
Can FAT and export packing be arranged?
Yes. Inspection, routine tests, agreed FAT scope, packing plan and shipment documentation can be coordinated for confirmed projects.
