Часто задаваемые вопросы

Please send us your required MVA rating, primary voltage, secondary voltage, frequency (Hz), cooling class (ONAN/ONAF/OFAF), vector group, impedance, and installation site conditions. We will respond with a technical proposal and indicative pricing within 24 hours.

The product can be produced according to IEC 60076 and customer technical specifications for power transformer applications. Routine and type tests including temperature rise, impulse, and short-circuit withstand are available. Third-party witnessed testing can be arranged.

Large power transformers are shipped with oil-filled or oil-free transport options depending on voltage class and destination. All units include full documentation: routine test report, nameplate data, packing list, and certificate of origin. Lead time is confirmed at order stage based on specification complexity.
