To provide an exact quotation, we need: rated capacity, primary/secondary voltage, frequency, vector group, tap changer type, impedance, installation site conditions (altitude, ambient temperature), and if possible, your loss or efficiency requirements. You can send us your technical specification sheet, and we will supply a complete parameter and quotation proposal accordingly.
Yes. We provide detailed installation and commissioning manuals together with the transformer. Remote technical guidance by experienced engineers is available, and on-site supervision service can be arranged if required (subject to separate quotation).
Transformers are packed with wooden crates, protected against moisture, shock and collision, suitable for sea, land or railway transport. We have experience shipping to many countries and can arrange complete export packing and transport according to your port and destination requirements.
The noise level is designed to meet the requirements of IEC 60076-10 standard. Exact noise value depends on capacity and cooling configuration. For noise-sensitive sites such as hospitals and residential communities, we can provide low-noise design. Please let us know your site requirement.
