These are the cells that contact busbars which are supplied from the same or two different sources, of which rated current is up to 1250 A and of which short circuit strength is up to 25 kA and these are obtained by utilizing busbar partition and busbar amplification cells together.

3 polar and (open- closed- grounding rod) 2 SF6 gas insulated cells and 3 position (open-closed-grounding rod) separators are used on these cells as a standard.

Busbar coupling cells are used;
