VBPK-35 (vacuum switches)

2022: Start of mass production

On September 16, 2022, Roselectronics announced the start of mass production of vacuum switches for transformer substations at railway infrastructure facilities and power grid companies. The equipment allows import substitution of switching devices of the Swiss company ABB, the holding said.

The first samples have already been delivered by Russian Railways for operation on the route of the Sapsan train on the route St. Petersburg - Moscow.

Roselectronics launched the production of analogues of electrical equipment ABB

A new line of vacuum circuit breakers was developed by NPP "Contact" (part of Roselectronics) to replace switching devices of imported production with a voltage of 35 kV. The equipment is used in the configuration of closed switchgears, transformer substations, as well as in distribution points.

The maximum operating voltage of the developed circuit breakers reaches 40.5 kV, and their mass is not more than 350 kg. The service life for switching resistance at rated current is at least 10 thousand cycles of switching-on-off.

According to the manufacturer's website, the VBPK-35-25/1600 U 3.1 switch is designed to operate in three-phase alternating current networks with a frequency of 50 Hz with an isolated or grounded neutral, as well as to protect electrical circuits in emergency modes with disconnection and switching on short-circuit currents.

As the executive director of NPP "Contact" Alexander Yudin noted, vacuum switches VBPK-35 developed within the framework of the import substitution program to replace foreign equipment, primarily at critical infrastructure facilities. The equipment has passed all tests and certification.

At the moment, mass production has been launched with full localization in Russia and industrial supplies are being made. In addition to railways, our switches are already used at the substation of JSC LOESK - Electric Networks of St. Petersburg and the Leningrad Region, he said (quoted by the press service of Roselectronika).
