MGTSV Loose layer stranded optical cable for mine

Classification:


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.

Main Features

  • A-class fiber core, long transmission distance, uniform thickness and fiber flexibility.
  • The blue flame retardant PVC is used for secondary sheathing, so that the optical cable has good flame retardant effect;
  • Stretch resistance, abrasion resistance, flattening resistance and impact resistance, and it can be repeatedly bent, twisted, wound and bent (the bending angle does not exceed 90 degrees), and it has good mechanical properties;
  • Its temperature cycle is stable, the sheath is complete, and it has good environmental performance such as water resistance and flame retardancy;
  • The precise control of the excess length of optical fiber and the stranded pitch of optical cable ensures that the optical cable has excellent tensile performance and temperature characteristics;
  • Light weight, small cable diameter, fast transmission speed and long distance. Good confidentiality, electromagnetic interference resistance, good insulation and good chemical stability.
