Core Structure and Performance Features

1. Advanced Structural Design

The KYN28-12 Medium Voltage Vacuum Switchgear adopts a fully enclosed metal armored structure. The cabinet is made of high corrosion-resistant aluminum-zinc alloy steel plate with an IP4X protection rating. Internal busbars, circuit breakers, cables, and low-voltage components are independently separated, effectively suppressing the spread of fault arcs. Equipped with a dedicated transfer mechanism, it facilitates the pushing and positioning of the trolley, supports front maintenance and wall mounting, and saves floor space.

2. Reliable Safety Protection

Equipped with a comprehensive "five-proof" interlocking system to prevent electrical misoperation; independent heaters can be selected for the circuit breaker compartment and cable compartment to prevent condensation corrosion; the cable compartment has ample space, allowing for neat wiring and convenient maintenance.

3. Strong Adaptability and Interchangeability

Compatible with multiple vacuum circuit breakers such as VS1-12, ABB VD4, and Schneider HVX; can be configured with voltage transformers, isolating trolleys, and other modules; the trolleys are universally interchangeable, reducing maintenance difficulty and costs.
