Abstract

The invention discloses a high-shield anti-interference soft cable, which comprises a PVC filling core; a center hole slot, four insulation wire core slots and one shield wire core slot are arranged on the PVC filling core; an aluminum bar is placed in the center hole slot, four insulation wire cores are placed in the four insulation wire core slots; shield wire cores are placed in the shield wirecore slots; an aluminum belt is arranged at outside of the PVC filling core; a semiconductor nylon belt is wrapped at outside of the aluminum belt, and externally extruded and coated with an outer sheath; the sheath is externally sleeved with a metal bellow. The cable can effective prevent radiation of a magnetic field, protect the cable itself, and improve the cable anti-interference ability; the metal bellow is installed on the outer sheath, thus the passage of the electromagnetic wave can be well inhibited and the cable has excellent shield effect.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a highly shielded and anti-interference flexible cable. Background technique [0002] At present, due to the continuous and rapid development of my country's economy, the power supply is very tight, which has triggered an upsurge in investment and construction of power infrastructure, especially the widespread use of high-voltage power cables in urban power grids. In the process of using the cable, the requirements for the cable are very high. Firstly, the cable needs to have good heat resistance, strength, and tensile strength, and the cable also needs to have good insulation performance, shielding performance and anti-interference ability. [0003] The radiation and leaked electromagnetic waves of cables not only seriously interfere with the normal operation of other electronic equipment, but also lead to equipment dysfunction and transmission errors. Therefore, reducing the el...
