Abstract
A detectable tracer element for use in underground detection applications includes a metallic wire, a non-fibrous insulating jacket integral with the wire, and a flexible, cut-resistant, non-electrically shielding woven protective tube surrounding the wire and jacket combination. The woven protective tube includes a plurality of non-metallic fibers woven around the wire and jacket combination such that the combination is disposed within the interior of the protective tube. In one configuration of the invention, the woven protective tube defines a substantially oval or circular tube weave. The substantially oval or circular tube weave is woven, such that, the tube weave is pulled or stitched into a flattened configuration for use in underground applications.
