Optical fiber cable installation in a pressure sewerage
A house connection for a cable in a medium conduit comprises a cable passage with which the cable is taken out of the medium conduit. The cable passage is provided with a cable tensioner with which a portion of the cable can be tensioned in the medium conduit. The cable passage is preferably part of a rotatable manifold.
1. Liquid pressure generator suitable for coupling to a cable, in particular the outer end of a cable, with which a cable can be drawn in a pipe of a medium conduit and the cable can be displaced in the pipe through the medium conduit through buildup of liquid pressure downstream of the liquid pressure generator, which liquid pressure generator comprises a central shaft and comprises an elastic ring therearound with which a diameter of the liquid pressure generator can be adapted to a diameter of the pipe of the medium conduit, characterized in that an intermediate body of elastic material is present between the central shaft and the elastic ring, the intermediate body being less elastic than the elastic ring,
wherein the liquid pressure generator comprises a sensor and a transmitter for wireless communication.
2. Liquid pressure generator as claimed in claim 1 , provided with a water-repellent layer which forms a barrier to flow of liquid through the liquid pressure generator.
3. Liquid pressure generator as claimed in claim 1 , wherein the intermediate body forms an envelope for electronics of the sensor and/or the transmitter.
4. Liquid pressure generator as claimed in claim 1 , characterized in that the elastic ring is replaceable after use.
5. Liquid pressure generator as claimed in claim 1 , wherein the intermediate body extends over at least 30% of the length of the liquid pressure generator.
6. Assembly of liquid pressure generator as claimed in claim 1 and a cable.
7. Use of a liquid pressure generator as claimed in claim 1 for guiding a cable through a medium conduit.
