Application Areas
Vacuum Interrupter (Circuit Breaker Core)
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.
Live Display Device
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).
Harsh Environment Applications
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.
Usage Instructions
- Partial discharge ≤5pC at 1.1 times rated voltage (unless otherwise specified)
- Complies with DL/T538-2006 (High Voltage Presence Indication Device)
- Custom dimensions available upon request
- Protect from damage, moisture, and contamination
- Complies with JBT10305-2001 (Technical conditions for post insulator of organic material in 3.6kV-40.5kV high voltage equipment)
- For areas below 100 meters or high altitude areas, specify in order notes
