GLVAC is a worldwide leading manufacturer of HV relay. The most significant difference between GLVAC HV relay and common relay: GLVAC use unique ceramic vacuum sealing technology, separate the sealed contacts from outside air to obtain high dielectric withstand voltage. The working voltage can be up to 70KVDC. Different voltage dielectric such as vacuum or high pressure gas can be filled in relay according to different applications. GLVAC HV relay can be divided into ceramic vacuum relay, vacuum reed relay, gas-filled relay according to insulating medium. On the base of contact set and control methods, GLVAC HV relay can be divided into SPST HV relay, SPDT HV relay, DPDT HV relay, latching HV relay.
