A heating cable (10) and a method of manufacturing a heating cable (10). The heating cable (10) comprises at least one conductor (12a,12b) extending along the cable (10), a conductive shield extending along the cable (10), and surrounding said at least one conductor (12a,12b); and at least one insulating separation layer (14a,14b) separating the conductive shield from said at least one conductor (12a,12b). At least a portion of said conductive shield comprises a shielding conductor (16) extending in a spiral around said at least one conductor (12a,12b), the spiral comprising a plurality of turns (16a-e), each turn (16a-e) being physically separated from a corresponding portion of an adjacent turn (16a-e). |
