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 360 mm.
5) VUCG.T consists of three single-phase units.
6) VUCG.B consists of one single-phase and one two-phase unit arranged as shown in
the dimension drawing for UCL.B.
7) Space required for protective equipment.
