Central Loose Tube Stranded Figure 8 Self-supporting Cable

GYXTC8S/GYXTC8A

Central Loose Tube Stranded Figure 8 Self-supporting Cable

The fibers are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. The tubes (and the fillers) are stranded around the strength member into a compact and circular core. Then, the core is wrapped with swelling tape longitudinally. After part of the cable, accompanied by the stranded wires as the supporting part, is completed, it is covered with a PE sheath to form a figure-8 structure.

Packing And Mark

OYI cables are coiled on bakelite, wooden, or ironwood drums. During transportation, the right tools should be used to avoid damaging the package and to handle them with ease. Cables should be protected from moisture, kept away from high temperatures and fire sparks, protected from over-bending and crushing, and protected from mechanical stress and damage. It is not allowed to have two lengths of cable in one drum, and both ends should be sealed. The two ends should be packed inside the drum, and a reserve length of cable not less than 3 meters should be provided.

Loose Tube Non-metallic Heavy Type Rodent Protected

The color of cable markings is white. The printing shall be carried out at intervals of 1 meter on the outer sheath of the cable. The legend for the outer sheath marking can be changed according to the user's requests.

Test report and certification provided.

    • Air Blowing Mini Optical Fibre Cable

      Air Blowing Mini Optical Fibre Cable

      The optical fiber is placed inside a loose tube made of high-modulus hydrolyzable material. The tube is then filled with thixotropic, water-repellent fiber paste to form a loose tube of optical fiber. A plurality of fiber optic loose tubes, arranged according to color order requirements and possibly including filler parts, are formed around the central non-metallic reinforcement core to create the cable core via SZ stranding. The gap in the cable core is filled with dry, water-retaining material to block water. A layer of polyethylene (PE) sheath is then extruded.
      The optical cable is laid by air blowing microtube. First, the air blowing microtube is laid in the outer protection tube, and then the micro cable is laid in the intake air blowing microtube by air blowing. This laying method has a high fiber density, which greatly improves the utilization rate of the pipeline. It is also easy to expand the pipeline capacity and diverge the optical cable.

    • ADSS Down Lead Clamp

      ADSS Down Lead Clamp

      The down-lead clamp is designed to guide cables down on splice and terminal poles/towers, fixing the arch section on the middle reinforcing poles/towers. It can be assembled with a hot-dipped galvanized mounting bracket with screw bolts. The strapping band size is 120cm or can be customized to customer needs. Other lengths of the strapping band are also available.

      The down-lead clamp can be used for fixing OPGW and ADSS on power or tower cables with different diameters. Its installation is reliable, convenient, and fast. It can be divided into two basic types: pole application and tower application. Each basic type can be further divided into rubber and metal types, with the rubber type for ADSS and the metal type for OPGW.

    • ABS Cassette Type Splitter

      ABS Cassette Type Splitter

      A fiber optic PLC splitter, also known as a beam splitter, is an integrated waveguide optical power distribution device based on a quartz substrate. It is similar to a coaxial cable transmission system. The optical network system also requires an optical signal to be coupled to the branch distribution. The fiber optic splitter is one of the most important passive devices in the optical fiber link. It is an optical fiber tandem device with many input terminals and many output terminals, especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH, etc.) to connect the ODF and the terminal equipment and to achieve the branching of the optical signal.
