Product Overview
XGN15-12 AC metal-enclosed ring main switchgear is used in industrial and civil cable ring networks and power supply terminals. It is commonly used for industrial and civil cable ring networks and small substations and switch stations, with the final selection based on rated data, drawings, and site conditions.
EPC companies, electrical contractors, utility project teams, panel builders, and industrial buyers can request configuration review for ring main switchgear. Please send single-line diagram, rated voltage, rated current, short-circuit level, protection scheme, busbar arrangement, and cabinet layout, quantity, destination, and any project standard requirements for quotation.
Model and Meaning
- XGN: indoor fixed box-type ring main switchgear
- 15: design serial number
- 12: rated-voltage class
- Confirm whether the ordered configuration uses a load switch, vacuum load switch, or fuse combination
