This versatility makes TiraThai's HV Switchgear an essential choice for efficient, resilient power control in diverse global applications.
Key Features and Engineering Excellence
TiraThai's HV Switchgear excels through its innovative, modular architecture, balancing compactness with superior safety and adaptability. The compact structure reduces floor space by up to 30% compared to traditional designs, while surface treatments like spraying or galvanizing ensure corrosion resistance and longevity in harsh environments. Each functional chamber is sealed by metal plates with independent pressure release channels, preventing arc propagation and enhancing personnel safety during faults.
Compatibility extends to advanced breakers: domestic ZN85-40.5 vacuum types for eco-friendly, maintenance-free operation; French SF1/SF2 SF6 for high-reliability arc quenching; and FP system SF6 for compact, high-performance interruption. The design supports door-closed operation, strong structural adaptability for over 198 wiring schemes, and complete "five prevention" functions—including anti-misoperation, live interval verification, and anti-error grounding—ensuring foolproof reliability.
Jinguan Electric's automated production—featuring precision welding, vacuum testing, and AI-driven quality inspections—guarantees defect-free assembly, with material options like cold-rolled steel, aluminum-zinc sheets, stainless steel, or aluminum plates for non-magnetic needs. Optional features such as integrated relays, surge arresters, and SCADA interfaces enable smart grid integration. Compared to conventional switchgear, TiraThai units offer 20-25% faster installation and lower lifecycle costs through modular scalability. These attributes not only comply with GB3906-199 but exceed it, providing users with a switchgear that thrives in high-stakes power distribution.
