Product Description

Leaky feeder can be installed in such a way that it spools from the rear of the tunnel boring machine as it moves along the tunnel drift. By using a cable spool mount and a rotating leaky feeder connector (Model RC), the leaky feeder cable spool is able to spin freely while also remaining connected to the overall leaky feeder communications infrastructure. This allows leaky cable to be attached along the length of the tunnel boring machine to facilitate radio communications.

A protection rating of IP51 can be achieved due to the close fit of the bushing, for protection against light oil, dust, and water
