Metalized ceramic core rods (alumina-based) manufacture vacuum interrupter cavities, providing airtight seals and electrical insulation for high-voltage current interruption. Applications include mining circuit breakers and generator protection systems.
Used in 10kV-40.5kV power systems to provide real-time indication of high-voltage conductor status, circuit breakers (SF6 and vacuum types), lightning arresters, and instrument transformers, ensuring operator safety.
Typical Parameters: Capacitance ranges 10pF-230pF (e.g., 90pF at 24kV), with withstand voltage of 68kV (power frequency) and 125kV (lightning impulse).
High-temperature industrial equipment: Supports and insulates electric furnaces and heaters, withstanding temperatures exceeding 1000°C without deformation.
Corrosion protection systems: Valve and pump seals in petrochemical equipment resist acid, alkali, and salt corrosion.
Medical and semiconductor equipment: Ceramic feedthroughs for implantable devices (e.g., pacemakers) and electrical signal feedthrough components in vacuum chambers for chip manufacturing.
