Improvements in the application of sheaths to electric cables

摘要

An installation for the sheathing of an electric cable body stretched the last by means of a tow rope inside a pipe of greater size that has been laid straight and reducing the diameter of the pipe to lengthen it and make it fit properly on the cable body, in which the tow rope is threaded through a long and sufficiently tight enclosure and is maintained at one end and connected at the other to a piston that is inserted into the front end of the hub and the latter is carried over the piston inside of the enclosure in which the tube is laid, this enclosure being kept under pressure which, acting on the piston, keeps the tow rope taut and the piston attached to it stationary while the tube is being carried on it within the enclosure.
