Frequently Asked Questions
Q
What is the rated voltage of the XGN15-12 box-type closed ring network switch?
The XGN15-12 is rated at 12 kV, making it suitable for medium-voltage distribution systems operating at this voltage level.
Q
What types of load switches are available for the XGN15-12?
Two types of load switches are available: Type I uses the FLN36-12 Load Switch, and Type II uses the FLN48-12 Load Switch, providing flexibility for different application requirements.
Q
What are the available external dimension options for the XGN15-12 switchgear?
The cabinet height (H) can be 1400 mm, 1600 mm (both for single-core cables), or 1800 mm (for three-core cables). Width (W) options are 375 mm, 500 mm, or 750 mm, and the depth (D) is fixed at 918 mm.
Q
What is the protection class of the XGN15-12 switchgear?
The XGN15-12 switchgear carries an IP3X protection class, providing protection against solid objects greater than 2.5 mm in diameter, suitable for indoor installation environments.
Q
What information should be provided when placing an order for the XGN15-12?
When ordering, customers should provide product ordering drawings including wiring diagrams, transformer capacity, main component model specifications, distribution branch circuits and capacity. If metering or reactive power compensation devices are required, the relevant meter/transformer configuration and capacitor capacity should also be specified, along with any surface treatment requirements.
Q
What are the key withstand voltage parameters of the XGN15-12 switchgear?
The XGN15-12 features a 1-minute power frequency withstand voltage of 42/48 kV (phase-to-phase/earth/isolation) and a lightning impulse withstand voltage of 75/85 kV. The secondary circuit 1-minute power frequency withstand voltage is 2 kV, ensuring reliable insulation performance.
