Removing moisture from hollow guiding members

A system for removing moisture, comprising:

• a plurality of cable ducts for guiding and protecting cables, the plurality of cable ducts being provided with an entrance opening for supplying a flow of gas and an exit opening for discharging a flow of gas, each cable duct of the plurality of cable ducts being provided with a first opening and a second opening;
• a coupling-in member for supplying a gas flow to a first number of cable ducts of said plurality of cable ducts by way of the first openings thereof, the coupling-in member being coupled gastight to the first openings of said first number of cable ducts, and being provided with a gastight feed-through opening for each cable included or to be included in one or more of the first number of cable ducts and with a gas-supply opening constituting said entrance opening of the system,
• a coupling-out member for discharging gas flowing out by way of first openings of a second number of cable ducts of said plurality of cable ducts, the coupling-out member being coupled gastight to the first openings of said second number of cable ducts, and being provided with a gastight feed-through opening for each cable included or to be included in one or more of the second number of cable ducts and with a gas-discharge opening constituting said exit opening, and
• a coupling-through member for a gastight coupling-through between the second openings of the first number of cable ducts and the second openings of the second number of cable ducts, the coupling-through member being provided with a gastight feed-through opening for each cable included, or to be included in, at least one of the cable ducts of the first and the second number of cable ducts.
