3. INSTALLATION OF THE SWITCHGEAR AT SITE 17
Cleaning of soiled silicone insulating parts
Perform cleaning work immediately before
assembly of the relevant component as follows:
• Remove surplus or dirty grease from the
silicone part with a soft, clean, non-fraying
cloth.
• Clean the silicone insulating part when required
with intensive cleaner M.T.X. 60 forte and a soft,
non-fraying cloth.
Important note
Only use intensive cleaner M.T.X. 60 forte
as the cleaning agent.
• Only moisten the cloth slightly with intensive
cleaner. Apply only moderate pressure when
cleaning the insulating parts of busbar
connections. Do not wipe from the black areas
towards the light insulating surfaces. By
adopting this procedure you avoid transferring
black, conductive material onto the light,
insulating area.
• After cleaning with intensive cleaner M.T.X. 60
forte, wipe the silicone insulating part with a
dry cloth.
Important note
As the cleaner causes the silicone to swell
slightly, it then has to dry for approx. 15
minutes in the air.
Greasing the insulating parts
Grease the components immediately before use
as follows:
• Use the quantities of assembly paste listed in
table 3.1.3.1.
• Silicone insulating parts on the busbar
connection:
Evenly grease the light, outer areas of the
silicone insulating part as shown in fig. 3.1.3.1.
• Blanking plugs for the busbar connection:
Evenly grease the light, outer areas of the
blanking plug as shown in fig. 3.1.3.2.
• Silicone insulating parts of plug-in voltage
transformers or test plugs:
Evenly grease the silicone insulating part as
shown in fig. 3.1.3.3.
• Silicone insulating parts of the blanking plugs
for voltage transformer sockets:
Evenly grease the silicone insulating part as
shown in fig. 3 .1.3.4.
