Product Overview
The structure of MGTSV optical cable is to put 250 μm optical fiber into a loose
The structure of MGTSV optical cable is to put 250 μm optical fiber into a loose sleeve made of high modulus material, and fill the loose sleeve with waterproof compound. The center of the cable core is a metal reinforcing core, and the loose sleeve (and filling rope) are twisted around the center strengthening core to form a compact circular cable core. The gap in the cable core is filled with water-blocking filler. Double-sided plastic-coated steel strip (PSP) is lengthwise wrapped and then extruded into a polyethylene inner sheath, and then squeezed into a layer of polyethylene outer sheath to form a cable.
The MGTSV cable follows MT386-1995 Test Methods and Judgment Rules for Flame Retardancy of Flame Retardant Cables for Coal Mines.
