Watch Pulling the cable in the pipe for 200 m video on DTube
The video shows the method of pulling a thread in a pipe laid underground to pull a steel cable, and then pull out an electrical cable. A pipe 200 meters long was already laid under the road and railroad without a cable. There was no large compressor, so we used a 300W pass-through fan. As a piston, a 1.5-liter pail was used.
