Shielding, monitoring and wrapping reinforced low smoke halogen free rubber jacketed flexible cable of coal mining machine

Abstract

The invention relates to a shielding, monitoring and wrapping reinforced low smoke halogen free rubber jacketed flexible cable of a coal mining machine. The shielding, monitoring and wrapping reinforced low smoke halogen free rubber jacketed flexible cable comprises main wire cores and monitoring wire cores and is characterized in that each main wire core comprises a power wire core conductor, wherein a first insulation layer is arranged outside the power wire core conductor in an extruded manner, a first halogen free semiconduction shielding layer is arranged outside the first insulation layer in an extruded manner, each monitoring wire core comprises a control wire core conductor, a second insulation layer is arranged outside the control wire core conductor in an extruded manner, a second halogen free semiconduction shielding layer wraps the second insulation layer, a monitoring wire core conductor is woven outside the second halogen semiconduction shielding layer, halogen free EVA sheath material is arranged outside the main wire cores and the monitoring wire cores and extrudes an inner sheath, an aramid fiber weaving reinforcement layer is woven outside the inner sheath, and alow smoke halogen free EVA sheath material is arranged outside the aramid fiber weaving reinforcement layer and extrudes an outer sheath. By the shielding, shielding, monitoring and wrapping reinforced low smoke halogen free rubber jacketed flexible, the requirements of low smoke, halogen freeness, low toxicity and flame retardance of the cable are met, the tensile performance of the cable is improved, and the service lifetime of the cable is prolonged.

Description

technical field [0001] The invention relates to a low-smoke and halogen-free rubber-sheathed flexible cable with shielding monitoring and wrapping reinforcement for coal mining machines, belonging to the technical field of cable distribution. Background technique [0002] Mining shearer shielding monitoring wrapping reinforced rubber sheathed soft cable sheath is mainly used to connect underground shearer and transmit power and control signals for the shearer. One end of it is connected to the shearer equipment and the other end is connected to the power supply. . During use, with the movement of the shearer, it is always in a periodic motion state of being coiled-straightened-recoiled-restraightened. The underground tunnel is very narrow, and the cables may be smashed and dragged at any time. Due to the harsh environment of use, the service life of the cable is very short. Often put into use for a short period of time there will be failures, resulting in the normal power...

AI Technical Summary

Problems solved by technology

[0006] c. The control wire core and monitoring wire core section of the shielded monitoring wrapped reinforced rubber-sheathed soft cable for mining coal mining machines are small, and it is easy to cause broken cores during frequent bending and retracting.
