Frequently Asked Questions
Is this page a final equipment specification?
No. It is a voltage-based selection entry. Final ratings, dimensions, components and interfaces are confirmed in the approved technical agreement and drawings.
Can Qiangchi review an EPC single-line diagram?
Yes. Send the SLD, BOQ and specification for functional-unit selection and a project-specific proposal.
Can drawings and FAT documents be supplied?
GA drawings, technical submittals and agreed inspection or FAT records can be coordinated for confirmed orders.

Confirm the Correct Voltage-Class Equipment
System voltage alone does not complete product selection. Confirm rated voltage, insulation level, rated current, short-circuit current and duration, frequency, functional units, cable arrangement, application and required standard before quotation.
