These are the cells that amplify the busbars of busbar segmenting cells to other busbar and contact them, of which rated current is up to 1250 A and of which short circuit strength is up to 25 kA.

3 polar and 3 position (open-closed-grounding rod) SF6 gas insulated or revolving separator are used for busbar amplification cells, for which switching is requested.

Busbar amplification cells are used for coupling of two busbars, together with busbar segmenting cells.
