Halogen-free environmental-friendly anti-electromagnetic interference sensor cable for mine

Abstract

The invention relates to a halogen-free environmental-friendly anti-electromagnetic interference sensor cable for a mine, belonging to the technical field of cables and is formed by concentrically symmetrically twisting three insulation cable cores, three reinforced ribs or six insulation cable cores and two reinforced ribs into a cable core by using a guide pipe as a center, arranging an inner shielding layer outside, compounding an outer shielding layer with the inner shielding layer and finally extruding and wrapping an outer jacket. The cable guide pipe of the halogen-free environmental-friendly anti-electromagnetic interference sensor cable for the mine can be used for sensing changes of liquid level and pressure under a deep well, and feeding the changes back to a terminal alarm device; due to the reinforced ribs, the mechanical stretching resistance of the cable is enhanced; due to a symmetrical concentric structure, the cable has a uniform electromagnetic field, small mutual interference and good electromagnetic compatibility; due to the compound shielding, the anti-electromagnetic interference performance is enhanced, and further the tensile strength of the cable is improved; and due to the use of a novel insulation and jacket material, low-temperature and high-temperature resistance, low-smoke halogen-free environmental friendless and other performance indexes are improved, and the halogen-free environmental-friendly anti-electromagnetic interference sensor cable is safer and more reliable in use, and can meet the requirements of working conditions of occasions of an oil well, a mine and the like, and serious working environment conditions.

Description

Technical field: [0001] The invention relates to a halogen-free, environment-friendly and anti-electromagnetic interference mine sensor cable, which belongs to the technical field of cables. Background technique: [0002] With the development of the economy, the demand for power resources is increasing day by day, and the amount of coal is also increasing. The mining and excavation of coal resources is becoming more and more difficult, and in deep wells, mines and other harsh environments with pressure changes, the lower end of the sensor system equipment is connected with the silicon pressure sensor and differential pressure transmitter, and the upper end of the cable is connected with the silicon pressure sensor and differential pressure transmitter. The ground measurement and control system is connected to the computer, and the cable is easy to break. It is impossible to accurately detect the change of liquid level and pressure, and timely feedback to the terminal detec...
