Application Areas:
Vacuum Interrupter (Circuit Breaker Core)
Metalized ceramic core rods (e.g., alumina-based) are used to manufacture the vacuum interrupter cavity, providing an airtight seal and electrical insulation, enabling high-voltage current interruption. Applications include mining circuit breakers and generator protection systems.
Live Display Device
Used in 10kV–40.5kV power systems, it provides real-time indication of the operating status of high-voltage conductors, circuit breakers (such as SF6 circuit breakers and vacuum circuit breakers), lightning arresters, or instrument transformers, ensuring operator safety.

Typical Parameters: Capacitance ranges from 10pF–230pF (e.g., 90pF at 24kV), with a withstand voltage of 68kV (power frequency) and 125kV (lightning impulse).

Strengthening stability and durability in harsh environments:

High-temperature industrial equipment
Support and insulation components for electric furnaces and heaters, capable of withstanding temperatures exceeding 1000°C for extended periods without deformation.

Corrosion protection systems
Valve and pump seals in petrochemical equipment resist acid, alkali, and salt corrosion.

Medical and semiconductor equipment

Medical: Ceramic feedthroughs for implantable devices (such as pacemakers) maintain a sealed bio-environment.

Semiconductors: Electrical signal feedthrough components within vacuum chambers ensure cleanliness in chip manufacturing.

For Instructions:
PD not more than 5pC at 1.1 times rated voltage without special instructions. Comply with the standard DL /T538-2006(High Voltage Presence Indication Device).
The dimensions can be made according to customer requirements.
Special attention: Prevent the product from damage, moisture and contamination.
Comply with the standard JBT10305-2001(Technical conditions for post insulator of organic material in the 3.6kV40.5kV high voltage equipment at customers end).
For areas below 100 meters or in high altitude areas, please indicate it in the order notes.
