Switchgear medium voltage GUDIRA-5110

Crewe GUDIRA-5110 is a switchgear with drawout element, with the selected compartments in a metal case with air isolation to ensure containment of the arc short circuit.

Designed for use in industrial power and distribution networks of electric energy of three-phase AC with frequency 50 Hz and maximum operating voltage up to 17.5 kV.


Through the use of modern switching equipment, and a number of design solutions achieved high reliability and safety of the switchgear.

Use in the construction of steel sheet with aluminum-zinc coating, and painting of doors, external doors and panels cell by a powder method provides excellent protection against corrosion.
