Zusammenfassung: | The invention provides a mining communication cable. According to the mining communication cable, extruded insulation layers outside a conductor form insulated wire cores, every two insulated wire cores are hinged oppositely to form a single cable core, an electric cable core is formed by hinging multiple cable cores, and an isolating layer, a drainage wire, a copper-polyethylene bonding protective layer, a fire resistant layer, an interlocking armor layer and an outer protective sleeve are arranged outside the electric cable core in sequence. The mining communication cable has the properties of resisting electromagnetic wave interference and being tensile, capable of bearing pressure, dampproof, resistant to fire, resistant to low temperature and resistant to weather, and is especially suitable for communication transmission in various strip mines. |
