Abstract

The invention relates to an anti-interference cable with electromagnetic shielding capability. The anti-interference cable comprises a wire core, an insulating layer, an outer sheath and a metal corrugated pipe, wherein the surface of the wire core is coated with a copper net, and the copper net is arranged in a permanent magnet mode; the insulating layer comprises polyvinyl chloride resin, a barium titanate thin film and polyester fiber cloth; the polyester fiber cloth is formed by weaving polyester fibers; and the polyester fiber is provided with a polyester fiber body, wherein an Ag-Ag composite membrane and a Cu membrane are sequentially arranged on the surface of the polyester fiber body from inside to outside.

Description

technical field [0001] The present application relates to the field of cable technology, in particular to an anti-interference cable with electromagnetic shielding capability. Background technique [0002] Cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. Cables in a broad sense are also referred to as cables for short. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection composed of the following parts; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. [0003] The radiation and leaked electromagnetic waves of cables not only seriously interfere with the normal operation of other electronic equipment, but ...
