High Voltage Ceramic Insulator for Power Feedthrough

Metalized ceramic tube body is one of critical part in vacuum power feedthroughs, which offer unmatched dielectrical strength and outstanding mechanical strength. In the meantime, the ceramic tube could make the leakage rate low to 1*10^-11Pa.m³/s after brazing between ceramic and metal components.

They are commonly made from high purity Alumina Ceramic, such as 96% alumina, 99% alumina. They can be shaped by dry pressed, Isostatic pressed. In order to increase the electrical insulation strength and keep the surface of ceramic body away from foreign contaminations, sometimes, the Ceramic Tubes needs to be with glass glaze finish.

We can proceed with small part-size to large part-size, the min. diameter can be 1mm, the largest diameter is up to 500mm. In order to meet customers' different needs, we offer a selection of types of metallization, the typical ones as below:

1. Ceramic tube + Molybdenum (Mo/Mn) metallization ............................2. Ceramic tube + Mo/Mn metallization + Nickle(Ni) plating

3. Ceramic tube + Silver(Ag) plating..........................................................4. Ceramic tube + Tungsten (W) metallization + Gold(Au) plating
