XGN15-12 / Product overview
Make the cabinet and switching-device choices explicit
Cabinet insulation and the medium inside a switching device are separate specification decisions.
Air-insulated cabinet
XGN15-12 is an air-insulated, metal-enclosed product family. State the required installation arrangement and service conditions.
Selected switching devices
Load switches, fuse combinations and circuit breakers are selected for the feeder duty. Confirm each installed device and its insulating or interrupting medium.
Coordinated installation
Review cable entry, operating access, room or enclosure dimensions, interlocks and secondary equipment against the selected panel layout.
Technical reference
Key specifications and their application
Use the reference values below to start selection. The confirmed unit, drawings and technical agreement define the supplied equipment.

| Item | Reference | How to apply it |
|---|---|---|
| Product family | XGN15-12 | Air-insulated, metal-enclosed cabinet |
| Rated voltage class | 12 kV | 11 kV network use subject to insulation coordination and utility requirements |
| Rated current reference | 630 A | Confirm the selected circuit and approved rating schedule |
| Frequency | Confirm from the selected datasheet | State the project frequency in the RFQ |
| Short-time withstand duty | Project-specific | Confirm current and duration for the selected panel |
| Functional panels | Load-break switch / fused switch / VCB / metering / PT | Final selection follows the project SLD |
| Switching-device medium | Confirm for each selected device | Distinct from the air-insulated cabinet classification |
| Dimensions and cable interfaces | Selected arrangement drawing | Confirm installation envelope and service access |
Configuration & interfaces

Selection questions
XGN15-12 questions
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.
