MGTSV Mining Cable SM 12 Core Armored G652D flame retardant sheath directly buried installations roadways tunnel shafts

MGTSV adopts loose tube fiber optic cable stranded structure, optical fiber into the pine casing made of high modulus polyester material, waterproof casing filling compound. The loose sleeve (and filling rope) is twisted around the metal center strengthening core (phosphating steel wire) to form a compact cable core, and the gap in the cable core is filled with water blocking ointment. Blue flame-retardant PVC sheath extruded from cable core. Using blue flame retardant PVC sheath, with good flame retardant properties; -Resistant to stretching, abrasion, crushing, impact, repeated bending, twisting, curving, bending (bending angle not exceeding 90°), gunshot, etc., with good mechanical properties; -Good environmental performance such as temperature cycling stability, sheath integrity, anti-seepage drip, flame retardant, etc; -Precision control of fiber residual length and fiber stranding
