FAQ

Please send the system voltage, frequency, rated current, short-circuit level, SLD, required functional units, protection concept, quantity and installation conditions. If an SLD is unavailable, our engineering team can start from the project load and distribution requirements.

Depending on the product family and project configuration, Qiangchi supplies solutions at 630A, 1250A, 2500A and 3150A. Final current rating is confirmed against the selected switchgear type, busbar design and approved technical specification.

RMU is commonly selected for compact distribution networks; GIS is useful where footprint and environmental protection are important; AIS offers accessible construction and flexible conventional arrangements. Selection should follow voltage, fault level, space, maintenance and lifecycle requirements.

Yes. These system voltages are normally matched to suitable 12kV, 24kV or 40.5kV equipment classes, subject to the project specification and insulation requirements.

Yes. We can review the single-line diagram, functional-unit arrangement, protection requirements and cable interface before preparing the technical proposal and GA drawing.

Dimensions depend on voltage class, functional unit, current rating, component selection, cable entry and project arrangement. Final dimensions are shown in the approved GA drawing.

FAT scope is agreed in the technical documents and may include visual and dimensional inspection, mechanical operation, interlock checks, wiring verification, insulation tests and functional checks. Witness requirements should be stated before order confirmation.

Lead time is confirmed according to configuration, quantity, drawing approval, component availability and inspection scope. Export packing and shipping documentation are arranged according to the contract and destination requirements.
