A cable protection pipes are made of cast iron and fastened to the rails alongside a sleeper in
place of a cable protection sleeper.
Different from the normal cable crossing by cable protection sleeper (notched sleeper),
no change of sleeper needed and the weight is approximately 28 kg, so installation can be
performed by a small number of people in a short time.
This cable protection pipe can also withstand tamping by a tamping machine, and provides
adequate cable protection functions.
The cable protection pipe can be used both for the short-term laying or long-term laying
because the center part of pipe are insulated by resin pipe.
It can be applied to 50N and 60K rail.
