Product Description

We provide relays for high voltage applications, which is notablely different from general relays by using particular impervious ceramic technology to keep relays' contacts in sealed container that is separate from air and obtain high dielectric strength. The relays can be filled by different medium for different application. Two kinds of medium, vacuum and high pressure gas, were normally used in GuoLi's relay.

Performance of Vacuum :

As very few gas molecule exists in vacuum, arc hardly occurs. Ideally, it is possible to obtain dielectric strengths of ****0V per 0.1 mm in vacuum. Because there is no air in vacuum, contacts is oxidation free. Thus, vacuum relays typically have low and stable contact resistance, which is ideally used in radio frequency (RF) condition.

Performance of high pressure gas:

Pure high pressure gas allows relays to obtain advanced dielectric strength and avoid oxidation. When relays are used for hot switching, gas can keep contacts from high temperature burning. These relays are ideal for high in-rush capacitive make and capacitive discharge loads found in ESD test equipment, cable test equipment and heart defibrillators. Gas-filled relays also provide low, stable leakage current in applications sensitive to current fluctuations - especially across open contact sets over long periods of time.
