Wire and cable research direction in electromagnetic compatibility

(1) The research of cable shielding structures, including various types of cable shielding materials, forms or composite structures, generally include: 1 metal tubular structure; 2 wire braid (different weaving density) structure; 3 wire winding (different density) structure; 4 metal Membrane pressure edge winding (or vertical package) structure; 5 steel tape armored structure; 6 metal plating (including physical or chemical plating) structure; 7 semi-conductive shielding material shielding; 8 conductive paint film structure; 9 above combination structure.

(2) Mathematical models and engineering calculation methods for shielding effects of different cable shielding structures under different frequency bands or different field sources.

(3) Different transmission forms of wire and cable, including: 1 twisted pair; 2 twisted pair shield; 3 star twisted; 4 star twisted shield; 5 coaxial structure; 6 double coaxial symmetric RF structures (partial shield plus total shield); 7 Triaxial structure; 8 Coupling of leaky cables (using electromagnetic coupling).

(4) How to ground and ground the effect of different cable transmission types.

(5) Electromagnetic compatibility tests, including electromagnetic interference testing, electromagnetic sensitivity testing, and shielding effectiveness testing.
