Open switchgears 220, 150, 110, 35 kV are made of unified prefabricated transportable blocks, consisting of a metal supporting frame with high-voltage equipment and elements of auxiliary circuits mounted on it.
The following are used as high and medium voltage switchgear switching devices:
– column-type vacuum circuit breakers VRS-110 of our own production on the 110 kV side
– column-type SF6 circuit breakers VGT-110, LTB145D1, DT1-145, 3AP1EG-145
– tank SF6 circuit breakers VEB-110 on the 110 kV side
– column-type SF6 circuit breakers LTB170D1 on the side of 150 kV
– column-type SF6 circuit breakers VGT-220, LTB 245D1, 3AP1DT-245 on the 220 kV side
– core vacuum circuit breakers VR35NS, VR35NSM of our own production on the 35 kV side
