High-End Vacuum Interrupter & Switching Apparatus
Vacuum circuit breakers (VCBs) are the core switching and protective devices inside medium-voltage power systems. By extinguishing electrical arcs inside hermetically sealed ceramic vacuum interrupters, VCBs deliver zero maintenance and long electrical endurance.
Features include solid-embedded pole construction, withdrawable handcart mechanisms for KYN28 switchgear panels, and smart FTU controller integration for outdoor boundary pole switches.
