Loose center tube single thin round steel wire armored optical cable (GYXTA33)
The structure of GYXTA33 optical cable is that 250 µ m optical fiber is sheathed in a loose sleeve made of high modulus material, and the loose sleeve is filled with waterproof compound. A layer of single thin round steel wire is twisted outside the loose sleeve to form a compact and round cable core, and the gap in the cable core is filled with water blocking filler. Plastic-coated aluminum tape (APL) is longitudinally wrapped and extruded with a layer of polyethylene inner sheath, and then armored with single thin round steel wire, and finally extruded with polyethylene outer sheath to form cable.
Product standards
GYXTA33 cable complies with YD/T 769-2010 and IEC 60794-1 standards.
Product features
• Excellent mechanical properties and temperature characteristics
• Double layer single fine round steel wire armored cable with stronger tensile performance
• The loose casing material itself has good hydrolysis resistance and high strength
• The tube is filled with special ointment, providing critical protection to the optical fiber
• Good compression resistance and flexibility
• Small size, light weight, easy to lay
• Use the following measures to ensure the cable waterproof performance:
- The loose casing is filled with a special waterproof compound
- Complete cable core filling
- Coated with plastic-aluminium strip (APL) moisture barrier
- Good water-blocking material to prevent longitudinal water seepage of optical cable
