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.
