MGTSV multi-loose tube miner cable

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.

Product features

• Good mechanical and temperature properties.
• Loose tube material has water resistance and high strength.
• The special ointment in the tube provides critical protection for the optical fiber.
• Good pressure resistance.
• Two parallel steel wires ensure the tensile strength of the cable.
• Double-sided plastic-coated steel strip (PSP) enhances moisture resistance and has anti-mouse function.
• The water blocking material prevents water seepage in the longitudinal direction of the cable.
• Using blue flame retardant PVC secondary sheath, flame retardant effect is good.

Product standard

The MGTSV cable follows MT386-1995 Test Methods and Judgment Rules for Flame Retardancy of Flame Retardant Cables for Coal Mines.
