The fibers are arranged in a loose, high-modulus plastic tube. A water-resistant filling substance is used to fill the interstice on the inside and outside of the tubes. In the middle of the core is a steel wire that, if required, is covered with polyethylene to provide strength.
To create a small, spherical cable core, tubers (and fillers) are stranded around the strength member. To create a cable, the plastic-coated aluminum tape is wrapped around the core and extruded into a polyethylene sheath.
Good moisture-proof and water-resistant performance is provided by the full section water blocking structure.
Ideal optical fiber protection is provided by special filling gel-filled loose tubes.
Resistance to corrosion High modulus phosphoric steel wire serves as the main component of strength.
It is simple to route the flexible buffer tubes in closures.
Outstanding temperature and mechanical performance.
Superior protection against UV rays, fungi, abrasions, and other outdoor elements is offered by jackets.
A 30-year lifetime is made possible by strict workmanship and raw material management.
