Product Description

High Resistivity Metallized Ceramic Vacuum Tubes

This Vacuum interrupter ceramic tube is made of special alumina material with high insulation resistance. It always work as ceramic insulator tube or ceramic insulating body in vacuum interrupter for medium or high voltage/ currency switch gear.

As its special application, a metal layer plating at both ends is must, also the glazed surface is needed. The vacuum interrupter ceramic tube we manufacturer have a reliable brazing strength, ideal hermeticity.

Small part-size to large part-size is avaibitlity, the min. diameter can be 1mm, the largest diameter is up to 800mm.The typical plating as below:

1. Raw ceramic + Mo/Mn metallization 2. Raw ceramic + Mo/Mn metallization + Nickle plating

We are capable of offering high precision Metallized Ceramic Tube via variety of grinding, CNC machining, cutting processes. The finest tolerance can be +/-0.001 for length, +/-0.01 for inner and outer diameter.
