I see frequent talk in this forum about SF6 switches and how they’re primarily used in Europe. I’ve worked on projects here in the States where we’ve specified them, but it always has to do with space and cable routing issues. The SF6 switches (as I know them anyway) are wider than they are tall, sit off the floor about 18” or so on legs, and the cables terminate on the front of the gear with some sort of elbow joint (please inform me of the proper term for these terminations if you know). This allows MV conductors with large bending radii to have enough room to sweep down from above (or below), since the terminations are at a lower elevation than for standard 90” tall gear.
Is this just a manufacturing standard for this particular company’s SF6 switch, or all they all made this way? Why is this low-profile arrangement only found on SF6 switches and not other types of air-break, vacuum-break, or other switches?
