Description
● MGXTWV Central Loose Tube Miner Optical Fiber Cable:
MGXTSWV fiber optic cable, the fibers, 200um or 250um, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape, over a thin inner PE sheath, the cable is completed with a polyethylene (PE) outer sheath.
● 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;
►Two parallel steel wires ensure tensile strength;
►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;
►MGXTWV cable complies with Standard MT386-1995 test method and decision rule of the flame retardant of the cable used in coal mine.
