Power technologyStart with the electrical duty
A useful RFQ connects the required capacity and voltage ratio to the actual load, grid and installation. A model name alone does not define the equipment. Use the following checklist and attach the available drawings; identify unresolved items instead of filling them with assumptions.
| Specification item | Information to provide |
|---|---|
| Capacity and quantity | Rated kVA/MVA, number of units, load profile and any future expansion requirement. |
| Voltages and frequency | Primary/secondary rated voltage, system highest voltage, frequency and tapping range. |
| Connections and fault duty | Vector group, neutral/earthing arrangement, required impedance and available fault information. |
| Losses, temperature and cooling | No-load/load-loss requirements with reference temperature, cooling mode and temperature-rise limits. |
| Site conditions | Indoor/outdoor location, ambient temperature, altitude, pollution/corrosion and enclosure requirements. |
| Physical and electrical interfaces | Terminals, cable/busbar entry, footprint, maintenance clearances, accessories and monitoring. |
| Standards and evidence | Destination specification, applicable editions, routine/type/special tests, drawing and inspection document list. |
| Commercial and delivery inputs | Destination, desired schedule, named port, requested trade/payment terms, packing and warranty requirements. |

Attach the available design inputs
A single-line diagram, load list, site/layout drawing and destination specification help align the proposal. Send the enquiry summary through the form, or contact Mingyu Ma by email to coordinate drawings. Clarify document revisions and unresolved items before final approval.
Final ratings, configuration, performance and supply scope are defined in the project technical agreement.
