Shielded Solid Insulated Switchgear (2SIS) Technology Technical Paper

This technical paper discusses the advantages of Shielded Solid Insulated Switchgear (2SIS) technology for medium voltage (MV) networks, particularly its ability to withstand harsh environmental conditions and high altitudes. It compares 2SIS with other switchgear types (AIS, SIS, GIS) and highlights how its conductive layer, connected to earth, maintains constant electrical field performance, preventing aging and internal arcs.
