MV Switchgears

MV Switchgears are designed, manufactured and tested for switching, protection and control purposes in alternating current systems from 1 kV to 52 kV according to the IEC 62271-200 standard and Tedaş MYD.

MV Switchgears are classified in 4 main groups as follows according to the IEC 62271-200 standard.

1. Subdivision Class
   • PM Partition : Switchgear providing continuous metallic partitions and/or shutters, intended to be earthed, between
     opened accessible compartments and live parts of the main circuits.
   • PI Partition : Switchgear having one or more non- metallic partitions or shutters between opened accessible compartments and live parts of the main circuit.
2. Internal Arc Classification (IAC)
   • AFL : MV Panel have from internal arc protection for the restricted and authorized personnel in front and lateral.
   • AFLR : MV Panel have from internal arc protection for the restricted and authorized personnel in front, lateral and rear.
3. Loss of Service Continuity (LSC)
   • LSC 2A : defines the switchgears that opening and interfering of switching compartment is allowed while only busbar compartment is energized.
   • LSC 2B : defines the switchgears that opening and interfering of switching compartment is allowed while both cable and busbar compartment is energized.
4. Isolation of Cells
   • Air Insulated
   • Gas Insulated
   • Liquid Insulated
