Frequently Asked Questions
What is the typical lead time for orders?
Standard models generally ship within 15–30 days, while fully customized units require approximately 30–45 days depending on specifications.
Do you support OEM and ODM customization?
Yes, we provide full customization for voltage levels, rated capacity, winding materials (Copper/Aluminum), and specific loss levels to meet local grid requirements.
What insulation classes are available for dry-type transformers?
We offer Class F (100K) as standard and Class H (120K) for heavy-load or high-temperature environments. Lower temperature rise options are also available.
What certifications do your products hold for international export?
Our products are manufactured under ISO9001, ISO14001, and ISO45001 systems and hold necessary certifications such as CCC and relevant test reports for global markets.
How are the transformers protected during international shipping?
We use export-standard reinforced wooden cases designed to withstand long-distance maritime and land transport, ensuring the equipment arrives in perfect condition.
What maintenance is required for dry-type transformers?
Our dry-type transformers are virtually maintenance-free due to the oil-free, epoxy resin cast design, which eliminates leakage risks and reduces operational overhead.
