The invention concerns a locatable locating tape of which the tape body (10) consists of two strips (11, 12) interconnected over their entire surface, the tape interior (19) comprising a plurality of conductors made of metallic material. In order to render the locating tape easier to locate, the conductors are made of copper which unexpectedly does not corrode in the ground even if one of the electrical conductors (21) is left blank and has passages (15) ensuring that there is a good electrical earth contact. Further conductors (22, 23) are sheathed by an insulation layer (28) which screens them electrically with respect to the ground and enables the location tape to be actively located. The sheathed conductors also improve the conventional passive location process. |
