Sourcing FAQ

How do I evaluate a Turkish transformer manufacturer?
Check the manufacturer's factory presence or production facility in Türkiye, product range and power/voltage classes, available test reports, and references for similar projects; verify compliance with required standards and inspect factory/test capabilities if possible.
What typical minimum order quantities (MOQs) should I expect?
MOQs vary by manufacturer and transformer size: smaller distribution units may be ordered in single units while large power transformers are typically project-based; ask each supplier for their MOQ and production batching policy.
Which certifications and tests should I request?
Request conformity to the applicable standards (IEC/ANSI/local), routine and type test reports, material certificates, and factory acceptance test (FAT) documentation for high-voltage or critical units.
What drives lead time for transformers?
Lead time is driven by transformer size/complexity, core and winding procurement, drying and oil treatment, testing schedules and current factory backlog; clarify expected schedule and critical-path items when requesting a quote.
