| 摘要 |
The invention concerns a protective sheath against radiation, in particular derived from electric field generated by electric cables (1, 2, 3) extending inside the sheath. The invention is characterized in that it comprises an electrically insulating plastic outer layer (4) covering an electrically conductive material layer (5), the sheath end including removable connecting means for connecting the electrically conductive material layer (5) to an electrical conductor (7) designed to be connected to the ground, said sheath enclosing or designed to enclose at least one neutral cable (1), one ground cable (2) and one phase cable (3) connected to an electric power distribution system. |
