Why are the busbars in high and low voltage distribution cabinets exposed? What are the harms?
The exposed busbars inside the cabinet facilitate installation and also save on costs. With the cabinet door closed, the busbars cannot be accessed, which ensures sufficient safety in use. Moreover, after the busbar is installed, it requires almost no maintenance, and it is rarely replaced throughout the life cycle of the cabinet. If the busbars that may be contacted upon opening the cabinet door are energized, it is recommended to use heat-shrinkable insulating film.
