Key Features and Engineering Excellence
TiraThai's KYN28A-24 Series Metal-Clad Removable AC Metal-Enclosed Switchgear is engineered for superior safety and modularity, featuring a metal-clad structure that provides armored protection against arcs and faults. The removable design allows for easy maintenance and upgrades without system downtime, with internal components accessible for quick inspections. The enclosure is constructed from corrosion-resistant materials like stainless steel or galvanized steel, ensuring durability in non-corrosive environments while supporting inclinations up to 5° for flexible installations.
The switchgear integrates vacuum or SF6 circuit breakers for reliable interruption, with complete "five prevention" interlocks—anti-misoperation, live interval verification, anti-error grounding, accidental closing prevention, and live part entry prevention—to enhance personnel safety. Jinguan Electric's automated production—featuring precision assembly, vacuum testing, and AI-driven inspections—guarantees defect-free units with IP54 protection against dust and water. Optional features like integrated relays and SCADA interfaces enable smart grid integration.
Compared to fixed switchgear, TiraThai KYN28A-24 units reduce maintenance time by 40% and offer 20-30% better arc resistance. These attributes not only meet but exceed GB 3906 and IEC 62271-200 standards, providing users with switchgear that balances compactness, safety, and scalability.
