مقبس فراغ الضغط العالي

Ceramic-to-metal sealing products not only have the characteristics of ceramic high temperature resistance, المقاومة للتآكل, but also have the strength and toughness of metal. They are widely used in electronic aerospace, medical industry and other applications.

تغذية: An assembly which provides for the transfer of electrical power, gases or fluids from outside a hermetic chamber to the inside. Feedthroughs can provide both a hermetic seal and electrical isolation from the chamber wall.
تغذية are sometimes referred to as ‘passthroughs.Ceramic feedthroughs provide the solutions for applications requiring hermeticity and electrical isolation.
In addition to remaining leak-free in high and ultra-high vacuum,many of feedthroughs can accommodate:
• High temperatures
• Cryogenic temperatures
• High pressure
• Aggressive chemicals
A feedthrough is basically defined by the requirements for installation, عازلة, and conductor material. The method of interconnection is flexible and left to the customer’s discretion.
