Anti-interference moisture-proof mining communication cable

Abstract

The invention discloses an anti-interference moisture-proof mining communication cable, relates to the field of cables, and aims at solving the problems that a present mining communication cable is relatively low in tension and impact resistance, water blocking performance, and shielding performance and relatively short in service life. The anti-interference moisture-proof mining communication cable comprises a water absorption layer; an inner waterproof layer, an outer insulating layer, an inner isolation layer, an outer isolation layer, a puncture preventive layer and an outer protective layer are arranged outside the water absorption layer successively from inside to outside; external projections are uniformly distributed outside the puncture preventive layer in the circumferential direction, multiple cores arranged surrounding the inner waterproof layer are arranged between the inner waterproof layer and the outer insulating layer, and a spring is arranged between the inner isolation layer and the outer isolation layer spirally along the length direction of the isolation layer, so that the cable has anti-compression and buffering effects, and can be recovered after being compressed. In addition, the tension resistance of the cable is enhanced, the service life of the cable is prolonged, and the cable is more versatile.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-interference and moisture-proof mine communication cable. Background technique [0002] With the acceleration of our country's modernization process, the coal mining industry is developing rapidly, and the scale and intensity of coal mining are increasing. Harsh environments such as flammable, explosive and strong electromagnetic radiation continue to appear. Therefore, the performance requirements for mining communication cables are relatively high, and the existing mine communication cables have the defects of weak tensile and impact resistance, poor water resistance, poor shielding performance, and short service life. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an anti-interference and moisture-proof mine communication cable. [0004] In order to achieve the above object, the present invent...
