Comewill factory's GCK Low Voltage Withdrawable Switchgear features high stability, strong electrical performance, and flexible maintenance. The system's rated operating voltage can reach up to 690V, the horizontal busbar rated current up to 4000A, and the short-time withstand current up to 80kA. The cabinet is constructed of high-quality galvanized steel plate, offering corrosion resistance, high strength, and multiple safety interlock protections.
1. Multiple security protections
· Reliable Isolation and Interlock: The Comewill high qaulity GCK low voltage withdrawable switchgear is divided into three mutually isolated zones—busbar room, functional unit room, and cable room—effectively preventing accident spread and facilitating live maintenance. The drawer units are equipped with mechanical interlock mechanisms. When the switch is in the closed position, the drawer doors cannot be opened, ensuring compliance with safety procedures.
2. Good electrical and structural properties
· Powerful power load capacity: Rated operating voltages up to 400V and 690V, with rated insulation voltages of 660V and 1000V. The horizontal busbar can handle a maximum rated current of 4000A, with short-term current tolerance up to 80kA (1 second) and peak current tolerance of 176kA.
· Robust cabinet structure: The cabinet frame features a double-folded edge technology with aluminum-zinc coated steel plates, ensuring corrosion resistance and structural integrity. The horizontal busbar is positioned at the cabinet top, completely isolated from functional unit zones and cable areas, guaranteeing sufficient safety clearance between the busbar and maintenance personnel.
3. Convenient operation and intelligent potential
· Easy installation and maintenance: The removable top cover of the horizontal busbar area facilitates on-site busbar installation.
