1- Install the busbar between the bushing of
the 1st switchgear’s disconnector and the 2nd
switchgear’s disconnector. Place the ball on the
busbar in the 1st row switchgear and tighten the
separator isolator busbar bolt with the torque
wrench from the sphere (with 50Nm force).
Apply the above procedures separately for three
phases respectively.
2- Insert busbars and spheres between separator
insulators of second switchgear and separator
insulators of third switchgear and tighten the
separator insulator busbar bolts through the
sphere with a torque wrench.

Put the number 1 base plate to its place and
mount it to the switchgear.
Connect the cable holder to L1 phase. Connect
the earthing head to the ground earthing.
Replace the bellows on the cable.
Put the number 2 base plate to its place and
mount it to the switchgear. Assemble the cable
clamp. Connect the cable earthing to the busbar
earthing.
Repeat these operations again for L2 and L3
phases.
Prepare the cable termination.
Installation of Toroid Transformers:
If Toroid transformers will be used in the
switchgears, transformers are prepared
seperately, mounted to the cables and fixed.
