The final paper describes compact medium voltage switchgear blocks, their classification, design and configuration in a way that complies with IEC standards. The second chapter discusses the classification of switchgear blocks, standards that indicate the design of switchgear blocks, the impact of SF gas on the environment and safety measures. The busbar compartment and the compartment for housing connections are separated from the switchgear compartment. Each switchgear block consists of a compartment in which the primary elements are located and the variants in which they can be designed, as described in the third chapter. The fourth chapter describes the configuration of switchgear blocks, which consists of individual fields as a separate unit with the examples given. The remaining chapters present in detail the designs of switchgear blocks from different manufacturers such as BVK, RM6, SM6, SafePlus/SafeRing, with regard to the installation location, their construction, insulation types and characteristics (arc extinguishing, control method, etc.) together with the nominal data for which they are designed.
