| FAQ |
Q: What is the difference between XGN15 and XGN66 high voltage ring main units?
A: XGN15 is compact small cabinet for underground pipe gallery, small load; XGN66 has larger cabinet space, expandable PT and lightning protection modules, suitable for industrial factory high voltage main distribution with larger load capacity.
Q: What advantages does GCS draw-out cabinet have over fixed GGD cabinet?
A: GCS drawer unit can be pulled out for maintenance separately without cutting off the whole busbar power supply, suitable for data centers, hospitals and other high-reliability power supply scenarios; GGD is low-cost for ordinary factory fixed power distribution.
Q: Can the whole set of switchgear realize remote monitoring and fault alarm?
A: Yes, we can configure intelligent communication instruments to upload voltage, current, power and fault signals to upper computer, supporting remote real-time monitoring and automatic alarm for overcurrent and short-circuit faults.
Q: Is the SF6 gas insulated high voltage cabinet safe for long-term operation?
A: The cabinet adopts fully sealed SF6 load switch with zero gas leakage design, stable arc extinction performance, no open arc risk during switching, safe for long-term unattended operation in underground and outdoor environments.
Q: Can the internal busbar and protection parameters be customized according to project demand?
A: Fully customizable, including copper busbar cross-section, circuit breaker breaking capacity, protection action current and delay time, matching photovoltaic, industrial, municipal and other different project load characteristics.
