Types of MV switchgear installations - Switchgear Content· Metal-Enclosed Switchgear: The Compartmental Type: The complete installation is enclosed by earthed metal and hence sometimes is called the "package type." The circuits are usually segregated into separate metal compartments, but the components of the circuit (bus bars, isolators CBs, etc.) are not necessarily in different compartments. The main insulation is air, and the CBs …
