Abstract
At least one conductive element combined with a magnetic absorbing mixture surrounding at least part of the conductor has a composite structure: a core is formed by a filament or fiber (rayon, nylon, glass) and a conductive coating (metal or metallic glass). There is so provided a high resistance element, with good mechanical properties and a great absorption of high frequencies. Applications: antiparasitic cables for ignition of internal combustion engines, instrumentation and low-pass cables, coaxial cables, shields and screens.
Claims15
An electric lossy element of the electric wire, cable or screen type, comprising:
- at least one conductive element, said conductive element being a composite structure including a non-conductive core of the textile, plastic or glass type coated with a thin conductive metallic layer;
- and
- a magnetic absorbing mixture at least partially surrounding said at least one conductive element, said magnetic absorbing mixture being non-conductive.
A radio frequency interference suppressor cable, comprising:
- at least one conductive element;
- and
- a magnetic absorbing mixture, said mixture at least partially surrounding said at least one conductive element;
- wherein said at least one conductive element includes a plurality of non-conductive fibers, each of said plurality of fibers being coated with a thin conductive metallic layer, said plurality of fibers being grouped together.
