KYN28-12 AC Metal-Enclosed Switchgear

Our key advantages of KYN28-12 AC Metal-Enclosed Switchgear

"Five-Prevention" Interlocking for Ultimate Safety: Our dedicated "Five-Prevention" interlocking protection system serves to completely prevent operational errors—specifically, preventing the accidental opening or closing of circuit breakers, operating disconnectors under load, applying ground wires to live circuits, closing circuit breakers while ground wires are attached, and accidentally entering live compartments. This system thoroughly eliminates the risk of high-voltage operational errors, thereby safeguarding the safety of operating personnel and preventing faults caused by human error.

Withdrawable Trolley Design for Maintenance Without Power Interruption: The circuit breaker utilizes a withdrawable trolley structure. If a fault occurs in a specific circuit, the corresponding trolley can simply be withdrawn for maintenance; the remaining high-voltage circuits remain completely unaffected, eliminating the need to shut down the entire high-voltage system. This significantly reduces downtime and is perfectly suited for high-voltage environments where continuous power supply is critical.

IP4X High Protection Rating: With an IP4X protection rating, the switchgear effectively blocks dust and moisture, thereby protecting the internal high-voltage components. This ensures stable and reliable operation, even in environments characterized by high humidity or high dust levels.
