Cable with high pressure resistance

Abstract

The invention discloses a cable with high pressure resistance. The cable comprises an inner core layer, a cable core and a tensile core, wherein the cable core is annularly arranged in the inner core layer; the tensile core is arranged at the axis center of the inner core layer; the external part of the inner core layer is provided with an elastic layer; a gap is formed between the elastic layer and the inner core layer; first elastic balls are annularly arranged at the gap; second elastic balls are arranged between two adjacent first elastic balls; the second elastic balls are abutted against the elastic layer; the external part of the elastic layer is provided with a wearing layer; and the external part of the wearing layer is provided with an armor layer. When the external part of the cable bears the extruding force, the cable can absorb the pressure through deformation of the first elastic balls and the second elastic balls so as to avoid directly transmitting the pressure to the cable core, and at the same time the armor layer can bear the external frictional force; and when the armor layer is fractured, the subsequent pressure is borne by the wearing layer so as to protect the elastic layer and guarantee normal usage of the cable.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a cable with high compression resistance. Background technique [0002] Cables are commonly used conductors in daily life. During the laying process of cables, manual or mechanical traction is required. During the traction process, due to the unevenness of the ground, the cables will be deformed to a large extent. After transmission, it is passed to the cable core, which is likely to cause deformation of the cable core and affect normal use. At the same time, after extrusion and deformation, the maintenance of the cable is more difficult, causing greater work pressure to the maintenance personnel. [0003] Therefore, it is necessary to design a cable with high compression resistance, relatively simple structure, relatively low cost, and suitable for popularization and use. Contents of the invention [0004] The technical problem to be solved by the present invention is to p...
