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 in mining circuit breakers and generator protection systems.

Live Display Device: Used in 10kV-40.5kV power systems to indicate operating status of high-voltage conductors, circuit breakers (SF6/vacuum), lightning arresters, or instrument transformers, ensuring operator safety.

High-Temperature Industrial Equipment: Support and insulation components for electric furnaces and heaters, withstanding temperatures exceeding 1000°C without deformation.

Corrosion Protection Systems: Valve and pump seals in petrochemical equipment resistant to acid, alkali, and salt corrosion.

Medical & Semiconductor Equipment: Ceramic feedthroughs for implantable devices (pacemakers) and electrical signal feedthrough components in semiconductor vacuum chambers.

Technical Instructions

Partial discharge ≤5pC at 1.1 times rated voltage (unless otherwise specified). Complies with DL/T538-2006 (High Voltage Presence Indication Device) and JB/T10305-2001 (Technical conditions for post insulator of organic material in 3.6kV-40.5kV high voltage equipment).

Custom dimensions available upon request. Products must be protected from damage, moisture, and contamination. For installations below 100 meters or in high altitude areas, please specify in order notes.
