Mine water-blocking type explosion-proof signal cable

Abstract

The invention discloses a mine water-blocking type explosion-proof signal cable, comprising a main body, a fastener, a first inorganic insulating tape, communication lines and isolation belts, whereinthe communication lines are arranged in the inner cavity of the main body, three communication lines are arranged in total, the communication lines are separated by the isolation belts, the ends, closed to each other, of the isolation belts are welded, and the first inorganic insulating tape fills a gap between the communication lines and the isolation belt. The mine water-blocking type explosion-proof signal cable is reasonable in structure, good in flame retardant property, strong in explosion-proof performance, good in anti-interference performance, good in mechanical properties, low in cost, safe in operation and very convenient in use, and performance of the cable is improved; and the mine water-blocking type explosion-proof signal cable has excellent water-blocking and moisture-proof functions, product performance completely meets operating requirements of a humid environment, and the practical application need can be well met.

Description

Technical field [0001] The invention relates to the technical field of communication cables, in particular to a water-blocking explosion-proof signal cable for mines. Background technique [0002] With the development of society, cables are used more and more widely, and there are more stringent and diverse requirements on the performance of cables. Continuously improving the performance of sheath materials is an urgent need for economic and social development. Explosion-proof cables have been widely used in places with explosive hazards. For example, in warehouses, chemical companies, gas stations, gas stations, petroleum companies and other places with extremely high safety requirements, explosion-proof cables are required to meet these places High requirements for safety. In order to prevent the storm shock wave caused by the explosion from damaging the cable and electromagnetic interference between the circuit and the surrounding equipment, the internal circular explosion-pr...

AI Technical Summary

Problems solved by technology

Existing explosion-proof cables are realized by installing a circular explosion-proof plate inside the cable, mainly steel wire armor and copper wire armor, so that the cable will not be damaged under the action of external force, but this structure reduces the flexibility of the cable. , bending; the addition of the explosion-proof plate will increase the weight of the cable itself, on the one hand, it will increase the difficulty of installation and laying

[0003] With the research and development of modern technology in our country, mineral mining continues to advance to deep and harsh environment areas. Various types of mine mining operations are increasing day by day, and the level of space operations is becoming increasingly complex and changeable. Due to the effects of environmental and meteorological factors, mine cables may Laying in a humid environment for a long time, water molecules may penetrate radially into the cable through the sheath and be attracted by the insulation, causing a decline in electrical performance, and even causing obstacles or malfunctions, resulting in unnecessary losses or even Safety of life and property
