Abstract
The invention discloses a wave-absorbing shielding cable and a processing technology thereof. The processing technology comprises the steps that an insulating material layer is extruded by a main machine used for extruding insulating materials at the temperature ranging from 150 DEG C to 165 DEGC, and a conductor layer is coated with the extruded insulating material layer; a wave-absorbing material layer is extruded by an auxiliary machine used for extruding wave-absorbing materials at the temperature ranging from 170 DEG C to 190 DEG C after the insulating material layer is extruded for 0.1-0.5 second, and the insulating material layer is coated with the wave-absorbing material layer. According to the wave-absorbing shielding cable and the processing technology thereof, the insulating material layer covering the conductor layer and the wave-absorbing material layer covering the insulating material layer are extruded through a double-layer extrusion mode, the production efficiency of the wave-absorbing shielding cables is improved, the production cost is reduced, and the wave-absorbing shielding rate is greatly improved.
Description
technical field [0001] The invention relates to the technical field of wires and cables, in particular to a wave-absorbing shielded cable and its processing technology. Background technique [0002] The current wire and electrical connection only includes a conductor layer and an insulating material layer covered outside the conductor layer. In order to improve the wave-absorbing and shielding ability of the wire and cable, the shielding layer is usually braided with a metal braid outside the insulating material layer, or through the insulation layer. Wrapping is carried out on the outside of the material layer to improve the wave-absorbing and shielding rate. However, the cost of weaving is high, the process is complicated, and the shielding effect on the high-frequency waves emitted by the conductor layer is poor, and the shielding rate is lower than 70%; the shielding rate is lower than 90% by wrapping. [0003] Therefore, the prior art still needs to be improved and dev...
