Loose Tube Armored Flame-retardant Direct Buried Cable
GYTA53(GYFTA53) / GYTS53(GYFTS53)
Loose Tube Armored Flame-retardant Direct Buried Cable
Product Features
Excellent mechanical and temperature performance.
Resistant to high and low temperature cycles, resulting in anti-aging and a longer lifespan.
Loose tube stranding cable core ensures stable cable structure.
Single steel wire serves as the central strength member to withstand axial loads.
100% core filling with water prevents cable jelly to ensure cable watertightness.
Aluminum tape longitudinally covers cable core as a moisture barrier.
Inner sheath effectively reduces external mechanical loading.
Corrugated steel tape longitudinally covers cable core and provides good crush resistance.
Outer sheath protects cable from ultraviolet radiation.

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.
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.

All Dielectric Self-Supporting Cable
The structure of ADSS (single-sheath stranded type) is to place 250um optical fiber into a loose tube made of PBT, which is then filled with waterproof compound. The center of the cable core is a non-metallic central reinforcement made of fiber-reinforced composite (FRP). The loose tubes (and filler rope) are twisted around the central reinforcing core. The seam barrier in the relay core is filled with water-blocking filler, and a layer of waterproof tape is extruded outside the cable core. Rayon yarn is then used, followed by extruded polyethylene (PE) sheath into the cable. It is covered with a thin polyethylene (PE) inner sheath. After a stranded layer of aramid yarns is applied over the inner sheath as a strength member, the cable is completed with a PE or AT (anti-tracking) outer sheath.
