<p>The arrangement has a metal shield (20) radially enclosing a single-conductor electrical cable and arranged above the cable. An uninterrupted tooth banding (22) made of high-permeable material encloses the metal shield. The metal shield comprises a contact unit at ends of the shield for contacting the shield. The metal shield is formed with enlarged electrical conductance value to reduce electrical leakage at the metal shield, so that shield current is induced. The shield current is same as conductor current of a cable conductor (12) during marginal case.</p> |
