1) Shielding rings are used only for insulation levels 650-275 kV and higher.
2) Space required for lifting the diverter switch, excluding the lifting equipment.
3) Dimension without shielding-ring.
4) For tie-in resistor switch add 370 mm.
5) VUCL.T consists of three single-phase units.
6) VUCL.B consists of one single-phase unit and one two-phase unit.
7) Space required for protective equipment.
