Loose Tube Armored Flame-retardant Direct Buried Cable

GYTA53(GYFTA53) / GYTS53(GYFTS53)

Loose Tube Armored Flame-retardant Direct Buried Cable

The fibers are positioned in a loose tube made of PBT. The tubes are filled with a water-resistant filling compound. A steel wire or FRP is located in the center of the core as a metallic strength member. The tubes and the fillers are stranded around the strength member into a compact and circular core. An Aluminum Polyethylene Laminate (APL) or steel tape is applied around the cable core, which is filled with filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE (LSZH) outer sheath.(WITH DOUBLE SHEATHS)

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.

      The OYI-FOSC-09H Horizontal fiber optic splice closure has two connection ways: direct connection and splitting connection. They are applicable to situations such as overhead, manhole of pipeline, and embedded situations, etc. Comparing with a terminal box, the closure requires much stricter requirements for sealing. Optical splice closures are used to distribute, splice, and store the outdoor optical cables that enter and exit from the ends of the closure. The closure has 3 entrance ports and 3 output ports. The shell of the product is made from PC+PP material. These closures provide excellent protection for fiber optic joints from outdoor environments such as UV, water, and weather, with leak-proof sealing and IP68 protection.
