High-voltage bus insulators SM are used for fixing current-carrying buses inside power cabinets and assemblies in order to fix and isolate live parts from the case and assembly panels, with the subsequent connection of power conductors to distribute electricity inside the switchboard.
The insulator is fixed on one side with a bolt to the mounting plate or housing, on the other side the bus bar is attached to the insulator. Each bus is installed on at least two insulators (at the ends of the bus), and it is also possible to install intermediate insulators (depending on the installation scheme and the length of the bus).
