Switchgears for outdoor transformer stations

(type RST Type for pylon transformer stations or in-built ones for brick transformer stations)

RST switchgears are LV distribution switchboards for consumption up to 1000 A. They are designed for transformer stations used for power supplying consumer sites with the nominal transformer power of up to 630 kVA. These switchgears are designed and manufactured in compliance with standards ČSN EN 61 439-1 ed.2, ČSN EN 61 439-2 ed.2 and ČSN EN 61 439-5 ed.2.
