China KYN28A-12 Mid-mounted Cabinet Suppliers - 10kV Armored Enclosed Switchgear Factory for Power Distribution
The product features a highly modular design. Key components such as the circuit breaker and isolation carriage are mounted on a removable cart, enabling flexible operation and easy maintenance through multiple positioning states including working, testing, isolation, and removal. The cabinet is constructed from high-quality aluminum-zinc coated steel plates through multiple bending processes, forming a fully enclosed metal armor structure.
It is divided into isolated compartments — busbar room, circuit breaker cart room, cable room, and instrument relay room — ensuring operational safety and preventing fault escalation.
Busbar Room
Dedicated compartment for main busbar connections, ensuring electrical isolation and safety.
Circuit Breaker Cart Room
Houses the removable circuit breaker cart with multiple positioning states for flexible operation.
Cable Room
Isolated space for cable terminations, facilitating safe installation and maintenance access.
Instrument Relay Room
Contains measurement and protection relays, separated from power components for enhanced safety.
The mid-mounted cabinet features a comprehensive "Five-Prevention" locking mechanism to prevent accidental operation, safeguarding personnel and equipment against misoperation at every stage of switching and maintenance.
