Product Overview & Key Features
This KYN28-12 12kV armoured withdrawable AC metal enclosed switchgear is a mainstream indoor complete distribution unit designed for three-phase AC 50Hz power systems. It is widely used for power reception, distribution, control, protection, and monitoring in electrical networks.
The equipment adopts an armoured assembled structure. The cabinet is fabricated from high-quality cold-rolled steel sheets processed by CNC bending and bolted assembly, ensuring high structural precision and mechanical strength.
Internally, it is divided into four independent metal compartments: circuit breaker chamber, busbar chamber, cable chamber, and instrument chamber. Each compartment is fully sealed and isolated to prevent fault propagation.
The circuit breaker adopts a centrally positioned withdrawable truck-type design, allowing smooth operation and precise positioning. Trucks of the same specification are 100% interchangeable. A complete mechanical and electrical interlocking system is provided between the truck, cabinet, and door, ensuring full "Five-Prevention" safety functionality and eliminating misoperation risks.
The system features a rational layout, excellent heat dissipation, and convenient maintenance, making it one of the most widely used mature solutions in 10kV distribution systems.
Application Scope
This equipment is widely used in 10kV power systems such as power plants, substations, industrial and mining enterprises, commercial buildings, residential communities, renewable energy stations, and data centers.
It serves as a core distribution device for low-to-medium voltage indoor electrical networks.
Flexible Procurement & Customization Capability
The company offers low procurement thresholds with a minimum order quantity of only 1 unit. Mixed ordering of different models, voltage levels, and configurations is fully supported, providing high purchasing flexibility.
Comprehensive customization services are available, including cabinet size adjustment, selection of different brands of circuit breakers and electrical components, customized incoming/outgoing line solutions, and integration of intelligent monitoring modules.
For customized orders, the technical team provides full-process support, including professional configuration proposals to ensure complete alignment with project requirements and operating conditions.
