  • Method for making a conductor, or electric circuit balanced in radioelectric interference such as micro-discharge and corresponding conductor or circuit
    Patent number: 6438250
    Abstract: The invention relates to a manufacturing process of an electrical conductor or circuit compensated for radio interferences, including those from the electrical circuit itself. An application of a semi-conductor material (2) of resistivity coefficient allowing the external surface of the conductor (1) to the electrical circuit to be maintained at a static electrical potential near to that of the conductor (1) and the random electrical discharge currents to be absorbed is made to eliminate the interface micro-discharge interference phenomena. Application in the field of HiFi, home automation, instrumentation.
