Integrated VDIS Ceramic Capacitor Modules | Plug-and-Play Voltage Detection Assemblies for MV Switchgear
Our integrated VDIS ceramic capacitor modules are pre-assembled, ready-to-install units combining ceramic capacitor rods, connection terminals and insulating housing in a single package. Designed for OEM switchgear manufacturers, these plug-and-play modules simplify assembly of voltage presence indicating systems (VPIS/VDIS) inside 12kV to 40.5kV switchgear panels.
Each module is factory-tested for capacitance, partial discharge and insulation resistance, reducing your in-house testing workload and ensuring consistent quality across production batches.
Key Features
