Abstract

The invention belongs to the technical field of cables, in particular to a polyvinylidene fluoride insulated electromagnetic filtering cable and a processing method thereof. The cable comprises an inner conductor, wherein an insulation inner layer having a thickness of 0.10-0.18mm is formed outside the inner conductor through extrusion; an electromagnetic filtering layer having a thickness of 0.01-0.06mm coats the insulation inner layer and an insulation outer layer having a thickness of 0.05-0.12mm is formed outside the electromagneticfiltering layer through extrusion; an outer sheath is formed outside the insulation outer layer through extrusion; the insulating inner layer and the insulating outer layer are made of polyethylene fluoride, the electromagnetic filtering layer is uniformly dispersed with a magnetic material, and the adhesion and compatibility of the electromagnetic filtering layer and the insulating layer are strong, so that the electromagnetic filtering performance andthe overall insulation performance of the cable are improved.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a polyvinylidene fluoride insulated electromagnetic filter cable and a processing method thereof. Background technique [0002] At present, the amount of information that needs to be transmitted in aerospace weapons and equipment is increasing, and the frequency of signal transmission is getting higher and higher. The transmission of high-frequency signals brings serious electromagnetic interference. If no protective measures are taken, high-frequency electromagnetic waves in space will Coupling to other wires and cables will cause the signal transmitted in the cable to be distorted, leading to misoperation of various electronic equipment in aerospace vehicles, with serious consequences. In addition, in the information warfare in the complex electromagnetic environment in the future, the implementation of strong electromagnetic pulse (EMP) interference against various ...
