China Mid-mounted Cabinet KYN28A-24, 10kV Armored Enclosed Switchgear Suppliers & Factory
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.
The mid-mounted cabinet features a comprehensive "five-prevention" locking mechanism to prevent accidental operation. Optional integrated protection devices enable intelligent measurement and protection. Designed in strict compliance with domestic and international standards such as GB and IEC, this product stands out with high reliability, compact structure, user-friendly operation, and safe maintenance, making it the preferred equipment for modern distribution network construction.

The modular design allows key components such as the circuit breaker and isolation carriage to be mounted on a removable cart. This enables flexible operation and easy maintenance through multiple positioning states: working, testing, isolation, and removal.
The cabinet is constructed from high-quality aluminum-zinc coated steel plates processed through multiple bending operations, forming a fully enclosed metal armor structure that provides excellent durability and protection.
The "five-prevention" locking mechanism is a comprehensive interlocking system integrated into the mid-mounted cabinet. It is specifically designed to prevent accidental or incorrect operations during use, significantly enhancing safety for operators and equipment.
The product typically features a rated current ranging from 1250A to 3150A and a short-circuit breaking capacity of 25kA to 40kA, making it suitable for medium to high-demand distribution network applications.
The cabinet is divided into four isolated compartments: busbar room, circuit breaker cart room, cable room, and instrument relay room. This isolation ensures that any fault is contained within a single compartment, preventing escalation and protecting other components.
This product is designed in strict compliance with both domestic GB standards and international IEC standards. This dual compliance ensures high reliability, safety, and compatibility for use in modern distribution networks worldwide.
