Abstract
The invention relates to a conduit length to be joined in use to adjacent ends of similar conduit lengths to form an electrical power supply conduit when housing one or more electrical conductors, for the supply of electrical energy to electrical machines, e.g. a mining machine adjacent the conduit, the conduit length being generally of "U" section and internally lined with a seal of flexible material having a corresponding "U" shaped cross section, upper ends of the "U" arms of the conduit each carrying rigid locating means each housing an elongate displaceable sealing means, the two sealing means abutting one another so as to normally close an elongate aperture of the conduit length.
