VDA Vacuum distribution switchgear

The VDA vacuum distribution apparatus is engineered as three-pole units for nominal voltages up to 24 kV, specifically designed for indoor installations in compliance with IEC 62271-200 standards.

This apparatus can comprise multiple independent fields, each capable of individual operation. All fields are enclosed in a common gas-tight steel housing, with SF6 gas providing effective insulation between the fields and the enclosure. Electric arcs in the circuit breakers and disconnector switches are reliably extinguished within vacuum chambers.

Available in both non-extensible and extensible configurations, the VDA apparatus provides exceptional flexibility, enabling the design of a wide range of single-pole scheme configurations.

In the past 20 years, we have successfully delivered over 3,000 units in 100 distinct configurations to customers across the globe. Driven by technical and environmental standards, we remain committed to innovating next-generation systems to meet the ever-evolving needs and challenges of the market.
