Abstract
The invention relates to a multifunctional irradiation crosslinking reinforced flexible cable of a coal cutter. The multifunctional irradiation crosslinking reinforced flexible cable of the coal cutter comprises a plurality of power line cores, a plurality of controlling line cores and a pilot line core. Each power line core, each controlling line core and the pilot line core are respectively formed by a conductor and an insulating layer extruded outside the conductor. Each insulating layer is formed by an inner insulating layer and an outer insulating layer. Each power line core, each controlling line core and the pilot line core are formed in the mode of wrapping a semiconduction shielding layer outside in an extruded mode. An inner sheath, an armor layer and an outer sheath are sequentially arranged outside the cable core from inside to outside. The multifunctional irradiation crosslinking reinforced flexible cable of the coal cutter is scientific and reasonable in structure, easy to manufacture and produce, reasonable in cost, good in usability, excellent in electric property, physical mechanical property, chemical stability, high-and-low temperature resistance performance, tear resistance and abrasion resistance, capable of bearing friction force of a large machine, and long in service life. The multifunctional irradiation crosslinking reinforced flexible cable is an ideal cable for the coal cutter.
