KYN28-12 Armored Mobile AC Metal Enclosed Switchgear

The KYN28-12 Armored Mobile AC Metal-Enclosed Switchgear is an indoor switchgear system designed for three-phase AC power distribution networks with a rated voltage of 12kV and a frequency of 50Hz. It integrates functions such as control, protection, and monitoring.

Product Advantages
Safety-Oriented Structure
The enclosure is made of metal and fully grounded, helping to isolate live parts and reduce exposure risks.Each functional area is separately compartmentalized to assist in managing internal arc protection.Mechanical interlocking systems reduce the likelihood of operational errors during switching or maintenance.

Stable and Consistent Performance
Equipped with a vacuum circuit breaker with tested electrical and mechanical characteristics.Independent compartments help maintain operational stability by containing faults locally.Designed for dependable function in standard temperature and humidity conditions.

Adaptable System Configuration
Modular design allows flexible assembly according to specific layout requirements.Suitable for various installation schemes such as single-busbar and sectionalized systems.Supports optional auxiliary devices and monitoring modules for broader applications.

Efficient Maintenance and Handling
Removable vacuum circuit breaker mounted on a handcart enables fast replacement and inspection.All operations, including cable connection and circuit breaker insertion, can be performed from the front.

Product Features
Compartmentalized Metal-Enclosed Construction
Includes four major compartments: circuit breaker, main busbar, cable, and relay/instrumentation.Each section is divided by metal plates or insulation barriers, which improves operational clarity and safety.

Removable Vacuum Circuit Breaker
Circuit breaker is installed on a mobile handcart for easy positioning.Operates in three defined states: service, test, and isolated. The movement between positions is guided by mechanical controls.

Product Applications
Power Distribution Stations
Applied in substations to control and distribute electricity for medium-voltage power grids.Assists in protecting transformers, feeders, and outgoing lines from faults and overloads.

Industrial Plants
Suitable for power-intensive sectors such as steel manufacturing, chemical processing, and mining operations.Supports internal power management, motor control centers, and safety interlocking systems.
