Product Type: MGTSV product structure: MGTSV standard mining flame-retardant fiber optical cable is set into the high modulus plastic beam tube, the inner tube filled with water blocking compound. Centre to strengthen steel, steel - polyethylene inner jacket strengthened bond between the production of beam tube and sheath filled with water blocking the high-density nonwoven fabric or waterproof ointment, and then outsource blue flame CMR .. Laying: aerial, pipeline operating temperature: -40 ℃ ~ + 60 ℃ Applications: Mine Features: 1. Proper design and precise control over loose tube fiber length, the cable has excellent tensile properties and temperature performance. 2. Within the core filled with ointment, to ensure watertight cable effect. 3. Selection of flame retardant jacket, suitable for all types of mines. Center beam tube: from inside to outside is optical fiber, optical fiber paste, loose sleeves, thin wire (a plurality of steel around the circle), steel, PE inner sheath, flame retardant outer sheath. Stranded: from inside to outside the center stiffener (usually with phosphate wire), optical fiber, optical fiber paste, loose tube, cable ties, cable cream, steel, PE inner sheath, flame retardant jacket. MGTSV mine cable not only inherits all the properties of optical fiber and cable, but also because of the special requirements of the coal industry and the addition of a number of special properties, mainly for additional performance: flame retardant and rodent characteristics, due to coal, gold, iron ore for accident-prone land, in order to ensure the accident remains unobstructed, the state requires all mine communications cable must have a safety coal safety certification mark. Buying Tips: When you purchase, please look for coal mine safety certificate when using fiber optic cable, online confirmation query to verify. RRT Tianrun a boat Technology Group specializes in producing MGTSV mining cable (with coal safety certification), OPGW, ADSS cable variety of models, welcome to come to counseling, guaranteed price concessions, quality clearance!
