7.2.1
Establish Gas Connections between Density Monitor and Pole columns
REV6
/REV7
In one equipment version, the switchgear is available with a gas
connection of type FlexLink.
The FlexLink technology makes it particularly easy to couple the
gas connections to the pole columns. (see Chapter "12.2" on
page 101)
We recommend that the following tools be used to connect the gas
couplings:
- T022:
Compact open-end wrench (open-ended spanner),
SW27
- WK001: Torque wrench (spanner) with ratchet adapter and
SW27 open-end wrench head
• Remove the protective caps from the gas couplings on the pole
columns and the gas piping.
• Grease the threads of the gas couplings as per L4.
• Connect the gas piping to all pole columns. The filling
connections are equipped with threads for this purpose. First
screw on the filling connections by hand, then tighten
provisionally using tool T022, and finally tighten using tool set
WK001 to a torque of 30 Nm. Use two wrenches for connecting
the filling connections.
• Retighten all couplings in the gas piping system.
