Your specification comes first

A previous supply milestone does not define a standard model for your site. OSTL’s confirmed power and distribution range is up to 10 MVA and up to 66 kV; dry-type transformers are manufactured up to 3 MVA. Confirm the exact configuration, standards and supply scope against your own project.
