cables/lines
(4) are tightly sealed (see
Fig. 2
) to prevent a “snorkel effect” in
rising water.

The seal must be gas-tight.
•
Use compression joints with an oil
stop etc.
•
Then encase the cable using a cast
resin fibre closure (2) .
Fibre enclosures outside the
underground distribution system:
Note!
•
Do not lay cables directly in the
ground!
•
A conduit (1) , among other things,
can be used to protect the cables!
