2. Switching compartmentA 3-position SF6 switch disconnector with epoxy cast resin housingis provided with inspection windows and available also with gasdensity indicator.

3. Cable compartment75 % of the space in the switch disconnector cubicle is reserved forpower cable connection making it possible to use both 1- and 3-phasecables with most simple unscreened terminations. Space is alsoadequate for cubicle accessories such as surge arresters, currenttransformers, second earthing switch etc. The door has an inspectionwindow and safety interlocking as standard. For cable entry there are3 individual cable gland plates in the bottom with support for a suitabledimensioned cable clamp. The bottom and the threshold of the cubiclecan be removed for ease of cable installation.

UES-A3/2 double springoperating deviceThe UES-A3/2 is used together with the switchdisconnector type SFG and the cubicles ofSDF.

The same mechanism is used to operate theswitch positions between OPEN ñ CLOSEand OPEN ñ EARTH. The UES-A3/2 is alsoused to operate the earthing switch EF. Therehas to be always the central interlockingmodule 1VFJ220001R2 fully assembledin the front of the UES-A3/2 during theoperation.

The UES-A3/2 uses the energy stored in 2 flatsprings. One (K-spring) to close and open theswitch disconnector and another (A-spring)to rapidly open the switch-disconnector.The A-spring charges the K-spring. The Aspring is charged during the manual or motoroperation from the open to the close positiononly once. During the operation the A-springwill be locked and not released before theimpulse from the fuse, shunt trip-coil ormechanical push button. Before that theUES-A3/2 can be used similarly to UES-K3/2.The operation shaft has to be returned to theopen position after the tripping.

The total manual operation angle is approxi-mately 180° (90°+ 90°). The switch iscon-nector is closed by a clockwise operation andthe earthing switch is closed by an anti-clockwise operation.

The mechanism is maintenance free duringthe whole lifetime (i.e. 30 years) in normalconditions. Mechanical endurance is 2000C/O (5000 C/O in a motor use only) and 1000O/Earth.
