Mining flame-retardant communication cable Category 5e explosion-proof wire

The communication cable used in coal mines is a key component of the underground communication system, mainly used for transmitting voice, data, and monitoring signals. Communication cables for coal mines shall comply with the standards of the Ministry of Coal IndustryMT/T 167—87The relevant standards such as "Mining Polyethylene Insulated Polyvinyl Chloride Sheathed Communication Cables" stipulate the models, specifications, technical requirements, test methods, etc. of cables to ensure their safe and reliable operation in coal mines.

Structure of communication cables for coal mines---High purity oxygen free copper is often used, in the form of single stranded copper wire or multi stranded copper wire, such as7/0.28mmThat is 7 root diameter0.28mmTwisted copper wires are used for transmitting electrical signals. The mainstream material for the insulation layer is polyethylene or polyvinyl chloride, and cross-linked polyethylene is used in special environments to isolate adjacent conductors and prevent signal interference or short circuits. The shielding layer can be in the form of copper wire braided shielding and aluminum-plastic composite tape wrapped shielding, which can block electromagnetic interference and prevent the leakage of the cable's own signal. The material of the armor layer is steel strip armor or steel wire armor. Some lightweight cables use galvanized steel strip, which can resist underground rock compression, mechanical collision, etc. The outer sheath is generally made of chloroprene rubber or flame-retardant polyvinyl chloride, which needs to pass flame retardant testing and have waterproof, moisture-proof, oil resistant, and flame-retardant properties.

Application scenarios of communication cables for coal mines---Laying in the tunnel, connecting the dispatch center with the telephones of each working face to achieve voice dispatch. Mobile equipment such as coal mining machines pass throughMHJYVEnhanced cable connection console, transmitting operation instructions and equipment status data. The underground camera of the monitoring system passes throughMHYVPShielded cables transmit high-definition video signals to ensure clear and stable images.
