发明名称 METHOD AND DEVICE FOR INTRODUCING A CABLE INTO A CABLE GUIDE TUBE
摘要 A method and device for installing a cable, more in particular a glass fibre cable, into a duct of a channelization system, the consideration which has led to this being based on the fact that the dragging working, considered from the cable inlet end, as caused by a flow of compressed gas effected in a relevant duct portion will increase according to a non-constant function and, dependent on the geometry and the length of the duct portion, can be insufficient over the initial part of it to compensate the friction forces exerted on the cable locally. According to the invention it has now been suggested to fulfil such a compensation function by exerting on the cable a pushing force working extending to the point where the dragging working will be sufficient to compensate the friction forces.
