Abstract:
A method for removing moisture from a plurality of cable ducts for guiding and protecting cables, each cable duct of the plurality of cable ducts being provided with a first opening and a second opening, the method comprising the steps of:providing 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 at least one of the first number of cable ducts and with a gas-supply opening;providing a coupling-out member for discharging gas flowing out by way of first openings of said second number of cable ducts, and being provided with a gastight feed-through opening for each cable included in at least one of the second number of cable ducts and with a gas-discharge opening;providing 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 first and the second number of cable ducts;continuously supplying a gas to the gas-supply opening of said coupling-in member; andmaintaining a continuous flow of the supplied gas through the first number of cable ducts and via the coupling-through member through the second number of cable ducts by maintaining a pressure difference between the gas-supply opening of the coupling-in member and the gas-discharge opening of the coupling-out member.
