Morgan Advanced Materials has launched a new service providing high-voltage ceramic-to-metal feedthroughs capable of performing with voltages in excess of 100kV DC while also withstanding pressures of up to 1,700 bar (25,000 psi).
FeedthroughsThe launch is in response to increased demand for higher-specification products from sectors including medical diagnostics.
Based around Morgan’s acclaimed Deranox 970 high dielectric strength ceramic, each product is designed and manufactured in line with specific customer requirements.
Yannick Galais of Morgan explained: “Ceramic feedthroughs have become widely established as the product of choice for high-voltage applications as other materials can struggle to cope from an electrical or mechanical point of view. We have seen a trend towards applications with highly tailored and extremely demanding requirements, meaning standard products are not always suitable in terms of their design and specification. Failure of these products cannot be tolerated as the ‘corona’ effect caused by undesired voltage build-up can result in catastrophic failure of an entire system and costly, unscheduled downtime.
“Drawing on their experience in the design of ceramic-to-metal brazed assemblies, our team of engineers work with customers from the outset to develop a fully integrated, optimised solution based on our proven range of ceramic materials, metallisation inks, high-temperature glazes and braze alloys. Materials are carefully selected and integrated into a design which will minimise the impact of the ‘corona’ effect and deliver reliable long-term performance in the most demanding conditions.”
Applications for high-voltage feedthroughs in the medical sector include, for anode and cathode connectors in x-ray, scanning and diagnostic equipment.
