FAQ
What is the XGN15-12?
It is a 12kV-class air-insulated ring main unit used for switching, protection and distribution in 11/12kV networks.
Can XGN15-12 be used on an 11kV system?
Yes. An 11kV network commonly uses equipment from the 12kV rated-voltage class, subject to the project insulation level and utility specification.
Which functional units are available?
Typical arrangements include load-break switch, fuse-switch, circuit-breaker, metering and PT units. Final availability follows the approved SLD.
What does 630A mean?
630A is the normal-current rating for the main circuit. Cable, busbar and feeder selection must also satisfy the project load and temperature-rise requirements.
What information is required?
Voltage, current, fault level, frequency, quantity, SLD, BOQ, cable details and technical specification.
Are dimensions fixed?
Panel dimensions and lineup length depend on the functional units, mechanism, cable entry and auxiliary equipment. Final dimensions are issued in the approved GA drawing.
Can FAT be arranged?
Yes. Routine tests, witness points and project document requirements can be agreed before production.
Can Qiangchi support OEM or EPC projects?
Yes. Project-specific configuration, drawings, component coordination and technical submittal support are available against confirmed requirements.

XGN15 identifies a metal-enclosed air-insulated ring-main-unit family; 12 identifies the 12kV equipment class. Functional configuration and installed switching devices are confirmed from the project SLD and specification.
XGN15-12 is an air-insulated product route for 10kV and 11kV distribution projects. It must not be confused with the QCL gas-insulated product family.
Service Conditions & Project Confirmation
| Ambient temperature | Subject to project specification and technical confirmation |
|---|---|
| Altitude | State the installation altitude in the RFQ; derating or design review may be required |
| Relative humidity | Confirm maximum and average project conditions |
| Pollution and corrosion | State pollution level, salt mist, dust and corrosive atmosphere where applicable |
| Seismic condition | Project-specific requirement to be confirmed |
| Installation | Indoor or outdoor enclosure, cable entry, room dimensions and service aisle must be specified |
Standards and Technical Compliance
The applicable IEC standards, utility requirements, project specifications, inspection plan and document list are confirmed during technical clarification. Compliance statements apply only to the final approved configuration; no unverified certificate or test claim is implied.
Engineering, Packing & Shipment
After drawing approval, Qiangchi coordinates production, inspection, routine testing and the agreed FAT scope. Finished equipment is protected for handling and export shipment according to cabinet size, destination, transport method and contractual packing requirements.
