Multi Loose Tube Miner Optical Fiber Cable(MGTSV)


·Products Description 

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

·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

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