GYFTA53 Fiber Optical Cable Double Jacket Double Armoured Direct Buried Outdoor Cable
Definition of GYFTA53
The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. FRP locates in the center of core as a non-metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is to protect the cable 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 outer sheath.
Characteristics
Good mechanical and temperature performance.
· Special tube filling compound ensure a critical protection of fiber.
· Crush resistance and flexibility.
· PSP enhancing moisture-proof.
