Broadband and high-frequency radiation leakage cables

Abstract

Broadband and high-frequency radiation leakage cable, characterized in that it comprises: an inner conductor; an insulating layer arranged outside the inner conductor, wherein the insulating layer consists of a mixture of a physically foamed polyethylene and a fluoroethylene propylene copolymer and the degree of foaming of the insulating layer gradually increases in the direction from the inner conductor to an outer conductor;an outer conductor arranged outside the insulating layer, wherein the outer conductor has several large groups of slots, the several large groups of slots being spaced apart from one another along the axis of the outer conductor, and wherein a single large group of slots comprises: a group of split figure-eight slots, consisting of several rows of figure-eight slots spaced apart from one another along the axis of the outer conductor, each of the rows of figure-eight slots comprising at least two figure-eight slots whose axes coincide, and wherein the axis of each of the rows of figure-eight slots is arranged at different angles to the axis of the outer conductor;a group of slotted slots comprising at least two rows of slotted slots spaced apart from each other along the axis of the outer conductor, each row of slotted slots comprising at least one long slotted slot hole and at least one short slotted slot hole whose axes coincide, and wherein the arrangement of the long slotted slots and the short slotted slots is different in two adjacent rows of slotted slots; a circular slot hole arranged between the group of split figure-eight slots and the group of slotted slots; a sheath arranged outside the outer conductor.
