High-voltage complete switchgear cabinets are designed to complete closed devices of electrical installations of three-phase current frequency of 50 (60) Hz with voltage 6 (10) kV in systems with isolated or earthed through arc suppression reactor neutral. Wide range of execution allows on the basis of KRUIT cabinets to complete the designed switchgear almost any necessary configuration and different purposes.
Advantages:
- individual approach to the Customer's requirements;
- application of advanced element base;
- simplicity and ease of maintenance;
- compactness.
