Multi Loose Tube Miner Optical Fiber Cable(MGTSV)


Product description/ PRODUCT

MGTSV fiber optic cable, the fibers, 200μm or 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress. The PSP is longitudinally applied over the cable core, a thin PE inner sheath is applied, then the cable is completed with a PE outer sheath.

Product Features/ PRODUCT

·Good mechanical and temperature performance
·High strength loose tube has good performance of water proof and high strength
·Special tube filling compound ensure a critical protection of fiber
·Good crush resistance and flexibility
·The following measures are taken to ensure the cable watertight:
    ·Steel wire used as the central strength member
    ·Loose tube filling compound
    ·100% cable core filling
    ·PSP enhancing moisture-proof and anti-rodent 
    ·Good water resistance material prevent longitudinal seepage 
·Blue flame retardant PVC as second sheath to make the cable has good flame retardant performance.

 

Product Standards / PRODUCT

·MGTSV cable complies with Standard MT386-1995 test method and decision rule of the flame retardant of the cable used in coal mine.
