Compression-resisting cable

Abstract

The invention discloses a compression-resisting cable. The compression-resisting cable comprises three cable main lines clustered together, wherein a cable sheath is arranged on the outer side of a clustered whole. A clustered mode of the three cable main lines that the three cable main lines form a lined-up structure, are located on the same horizontal plane and do not mutually extrude in the vertical direction, and a cross section of the cable sheath is of a flat or elliptic structure. The cable main lines are of woven structures. An independent insulating sheath is wrapped on the outer side of each cable main line and is made from ethylene propylene rubber. The thickness of the insulating sheath in the middle one of the three cable main lines is more than 20% larger than that of insulating sheaths of adjacent cable main line on two sides. Main line conductors inside the compression-resisting cable are not interfered and extruded and are small in destructive force, good layer recovering performance and excellent in overall compression resistance.

Description

technical field [0001] The present invention relates to cables, in particular to compression cables. Background technique [0002] The structure of the cable is roughly that there are multiple main wires inside, and the outside is wrapped with a jacket. Of course, the main wires are also individually covered with sheaths. However, in reality, conveyors are used in some sand mining fields and coal storage yards, and the power cables are all removable. It is unavoidable that there are often large excavators and bulldozers traveling back and forth. Normal cables cannot withstand repeated rolling, and the damage and replacement rate of cables is very high, resulting in great waste. [0003] Therefore, after the current round ordinary cable is rolled, its insulation is damaged to form a phase-to-phase short circuit and power damage. A pressure-resistant cable is urgently needed to solve this problem. [0004] The Chinese patent with publication number 202258436U and publication ...

Problems solved by technology

[0005] The above public documents only change the internal structure to a braided structure, and add a high-elastic silicone rubber sheath layer on the outside to avoid strong pressure. In fact, we see that the problem he needs to solve is secondary to the pressure resistance, and the most important thing is to strengthen The torsion and bending performance of the cable is affected, so the compression effect achieved by the public literature is not good enough, or even the effect is very poor, and it is impossible to withstand the rolling of large machinery for a long time.
