For decades Kyocera has produced high-voltage (30kV or higher) ceramic feedthroughs to meet customer requirements.
We have developed design and simulation technology, ceramic materials for higher voltages, and a performance evaluation system that covers a wide variety of product shapes and specifications. We solve various problems of high voltages for our customers.
Consulting with our team - from the initial design stage of high-voltage products to reducing the risk of discharge breakdown.
It is possible to carry out electric field simulation based on product shape. We can propose a robust high voltage insulator design structure based on our abundant experiences.
We propose the most suitable ceramic, from a wide range of materials, according to the required characteristics.
In this section, we will introduce the expected effects of replacing the conventional alumina material with the “high voltage-resistant alumina AH100A” material (reduction of component size and conditioning time).
Creeping dielectric resistance distance: 2 mm
Degree of vacuum: 10-４ Pa or less
Other measurement conditions of Kyocera
Sample thickness: 1 mm
Other JIS C 2141 compliance
50% reduction in ceramic parts due to improved voltage resistance*Kyocera's calculation
Significant reduction in conditioning time to high voltage (approximately 1/10th the time compared with conventional alumina A479)
Elevated voltage speed: 1kV/min
Hermeticity: 10-3 Pa or less
Metallization type of AH100A: Ag-Cu-Ti
We have equipment to measure high voltage resistance and hermeticity. Performance evaluation can be conducted by making customized fixtures.
Kyocera is able to test up to MAX DC120kV. For higher voltage design, please contact us.
Values are based on typical material properties and
may vary according to product configuration and manufacturing process.
