JSC VEI-AVIS is founded in 1992. The main sphere of the enterprise activity is the development of new types of high-speed vacuum switching devices and control circuits on the basis of research of the physical processes in high power pulse discharges in vacuum.

VEI-AVIS has developed a range of triggered vacuum switches intended for high-voltage and high-current pulse sources switching. A series of high-voltage unipolar vacuum contactors both for AC and DC is developed. Development of DC high-voltage vacuum circuit breakers is also conducted. The enterprise owns a number of high-voltage pulse stands with the test equipment on which researches and tests of new devices are conducted.
