Novel discharge anti-magnetic anti-interference high-energy irradiation cross-linked cable

Abstract

The invention discloses a novel discharge anti-magnetic anti-interference high-energy irradiation cross-linked cable. The cable comprises a plurality of cable cores, a cabling filling layer, and a sheath layer, wherein each cable core comprises a copper conductor and an insulating layer; the outer side of each copper conductor is wrapped with each insulating layer; a semi-conductive material lining layer further wraps the outer sides of the plurality of cable cores; the spaces between the semi-conductive material lining layer and the cable cores are filled with the cabling filling layer; and the sheath layer wrap the outer side of the semi-conductive material lining layer. A semi-conductive layer is added between a sheath and an insulation part; electrons passing through the sheath are led out of a product through the semi-conductive layer; the structure not only can effectively protect the insulation part from being affected by electron accumulation when the sheath is irradiated, but also can improve the external shielding effect of the product; and finally, the effects of electron leading-out and magnetic interference resistance are achieved.

Description

technical field [0001] The invention belongs to the field of cable manufacturing, in particular to a radiation cross-linked cable. Background technique [0002] Compared with ordinary cross-linked cables, irradiation cross-linked cables have high wear resistance, scratch resistance and crack resistance, high-level heat aging resistance, and unique radiation resistance. The insulation and protection of irradiation cross-linked cables The cross-linking of the sleeve must use an electron beam accelerator to irradiate and cross-link the product. When irradiating the sheath, the electron beam cannot completely penetrate the sheath layer and the insulation to reach the conductor, so a large number of electrons accumulate inside the insulation, and to a certain extent, it will cause the breakdown of the insulation layer, resulting in the scrapping of the product. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention...
