MGTSV Loose layer stranded optical cable for mine
MGTSV optical cable adopts loose-jacketed stranded structure, and the optical fiber is sheathed in a loose tube made of high-modulus polyester material. The loose tube is filled with waterproof compound (water-blocking ointment). Loose tube and filling rope are twisted around the metal central reinforcing core (phosphating steel wire) to form a compact cable core, and the gaps in the cable core are filled with water-blocking ointment. The cable core is longitudinally wrapped with plastic-coated steel strips on both sides, and then the PE inner sheath is extruded, and then the blue flame-retardant PVC sheath is extruded.
