  • One such conduit is a piastic pipe.
  • This pipe is made from plastics and has a single channel inside A number of cabies are inserted into the pipe and are protected by it.
  • a second type of protective conduit comprises a concrete U-shaped channel with a concrete lid placed over the top when the cables, wires and such like are in place.
  • a common practice when such problems arise is to try to push through a smaller conduit and then insert the new cable through the smaller conduit.
  • a typical practice in cable installation is to bury a 150mm diameter pipe made from fibre reinforced cement or PVC and to pull the cables through this.
  • a flexible smaller conduit of e.g. 35mm diameter is pushed through.
