The structure of GYFTZA53 strand loose tube cable is to insert 250 μ m optical fiber into a loose sheath made of high modulus material. Which is filled with waterproof compound. The center of the core is a glass fiber reinforced plastic (FRP). Which loosening the sleeve (and filling rope) around the center reinforced core to synthesize a compact and circular core. The gap of the cable core is filled with water blocking paste. After squeezing the polyethylene inner sheath. Then wrapped with a layer of aramid fiber before squeezing the polyethylene outer sheath into the cable.

Product Feature

• With very good mechanical properties and temperature characteristics.
• The sheath material itself has good hydrolysis resistance and high strength.
• The sheath is filled with special ointment, and the key protection of the optical fiber.
• Good pressure resistance and softness.
• The following measures are adopted to ensure the waterproof performance of the optical cable.
  1.  Center strengthening core of a single steel wire.
  2. The loose sheath is filled with a special waterproof compound.
  3. Complete cable core fill.
  4. Plastic aluminum strip (APL) moisture-proof layer.
  5.Double-sided plastic steel strip (PSP) improves the moisture resistance of optical cable.
  6.Good water resistance material to prevent longitudinal water seepage of optical cable.
