In the assembly hall the specialized units are first pre-
assembled. This division allows us to devote the neces-
sary care to obtaining a perfect balance with, and a cor-
rect assembly of the various components. In the next
stage the cubicles are assembled. This stage is subject
to strict assembly procedures.

After assembly, all cubicles undergo an extremely
thorough control. The electrical tests include resistance
measurements on the circuit breaker switch and earthing
switch. The cubicle is subjected to a voltage test of 28 kV
/ 1 min. The most striking test is the one where the clos-
ing speed of the load break switch and earthing switch
is measured. One can even check the post-vibration of
the electrical points during switching on a digital screen.
The mechanical tests are used to check all fitting mate-
rial, and to examine the correct positions of parts and in-
terlocks.
