Abstract
A bushing arrangement for passing at least one electrical cable with conductive shielding through an opening in a wall while providing protection against electromagnetic overtension or electrical interference comprising an electrically conductive bushing in the wall opening that is electrically connected to earth ground potential, and electrically connecting an electrically conductive tape between the electrically conducting shielding and the electrically conductive bushing so as to connect the conductive shielding to earth ground potential.
Claims16
A bushing arrangement for passing at least one electrical cable through an opening in a wall to provide protection against at least one of electromagnetic overtension and interference, said busing arrangement comprising:
- an electrically conductive tape substantially made of an electrically conductive rubber by the addition thereto of carbon particles in the form of carbon black;
- and
- an electrically conductive cable shielding of said at least one cable being in contact with said electrically conductive tape and functioning to connect said cable shielding to earth ground.
A method for passing at least one electrical cable having electrically conductive shielding through an opening in a wall while providing protection against electromagnetic overtension or electrical interference comprising the steps of:
- placing an electrically conductive bushing in said opening that is electrically connected to earth ground potential;
- using an electrically conductive tape to connect said electrically conductive shielding to said electrically conductive bushing so as to connect said conductive shielding to earth ground potential.
