METHOD OF SCREENING THE MAGNETIC FIELD GENERATED BY AN ELECTRICAL POWER TRANSMISSION LINE AND ELECTRICAL POWER TRANSMISSION LINE SO SCREENED

摘要

An electrical power transmission line (1), comprises at least one electrical cable (3), a conduit (2) of ferromagnetic material enclosing the electrical cable (3) and comprising a base (5) and a cover (6), and electrical contact elements (7) for electrically connecting the base (5) and the cover (6), wherein the electrical contact elements (7) are selected from the group consisting of metal fusion joints and metal resilient members suitable to pierce the ferromagnetic material, so that an electromagnetic continuity between base (5) and cover (6) can be provided for improving the magnetic shielding properties of the conduit (2).
