Elastic pressure-resistant cable suitable for high-pressure environment

Abstract

The invention relates to an elastic pressure-resistant cable suitable for a high-pressure environment. The cable comprises a cable body wrapping set, and a flame-retardant layer, an armor layer and awear-resistant outer wrapping layer sequentially wrap the cable body wrapping set from inside to outside, and an elastic pressure-resistant wrapping set used for buffering and offsetting pressure whena cable body is extruded or pressed and providing restoring force for the cable body after extrusion or pressing is finished is wrapped in the cable body wrapping set. Compared with the prior art, byarranging the elastic pressure-resistant wrapping set composed of an elastic pressure-resistant sleeve, an elastic buffer plate and a central bone rod, the interior of the cable is hollow and has thecharacteristics of high elasticity and pressure resistance, the weight of the cable is reduced, and after the cable is extruded or pressed, the elastic pressure-resistant wrapping set can protect thecable body from being broken; besides, the cable has very high elasticity and can be quickly reset after being extruded or pressed, and the use performance is not affected.

Description

Technical field [0001] The invention relates to the technical field of cable production, in particular to an elastic pressure-resistant cable suitable for high-pressure environments. Background technique [0002] Cables are usually twisted by several or several groups of wires (at least two in each group), each or each group of wires are insulated from each other, and often twisted around a center, the entire outer bread is highly insulated Overlay. It has the characteristics of internal energization and external insulation. It is often used to transfer electricity or information from one place to another. [0003] There are many types and shapes of cables, which can be applied to various harsh and complicated environments. However, most of the existing cables are solid cables, which are not only heavy in quality, but also when squeezed or pressed, the inner cable body is easily squeezed by other parts of the cable, causing the cable body to break and cause equipment failure; in...

Problems solved by technology

However, most existing cables are solid cables, which are not only heavy in weight, but also when squeezed or pressed, the inner cable body is easily squeezed by other parts of the cable, causing the cable body to break and cause equipment failure; in addition, Less elastic and unable to recover on its own after being squeezed or pressed
