Non-metallic Strength Member Light-armored Direct Buried Cable

GYTY53/GYFTY53/GYFTZY53

Non-metallic Strength Member Light-armored Direct Buried Cable

The fibres are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. A FRP wire locates in the center of core as a metallic strength member. The tubes (and the fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. 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.
