FAQ
What is the lead time for a 500 kVA oil-immersed transformer?
Standard production lead time is 30–45 days after drawing approval. Stocked ratings can ship faster. Sea freight to most ports takes 25–35 days.
Can you customize the 500 kVA oil-immersed transformer to ANSI or IEC standards?
Yes. We build to both IEC 60076 and ANSI C57 standards, and customize voltage, capacity, vector group, impedance, losses and accessories to your specification.
What certifications does the 500 kVA oil-immersed transformer carry?
Units are available with UL, CE, IEC 60076 and ISO 9001 documentation; marine units carry CCS / DNV / BV / ABS as required. Full factory test reports are provided.
