Abstract
A detectable pull tape comprising at least one elongated conductive wire extending longitudinally in the tape, wherein each elongated conductive wire has a coating of insulation, a woven outer cover formed from nonconductive warp and nonconductive weft yarns, the warp yarns extending longitudinally in the tape and the weft yarns extending transversely in the tape and weaving over and under the warp yarns, and a set of binder yarns extending longitudinally in the tape, the binder yarns weaving with the weft yarns on at least one side of the conductive wires to lock the warp yarns and the conductive wires in position relative to each other. A method of detecting the location of conduit using a detectable pull tape is also disclosed.
