Double Sheath Steel Tape Armored Fiber Optic Cable GYTA53 / Aluminum Armored Direct Buried Cable
The 250µm fibers are housed in PBT loose tubes filled with water-blocking gel. A central steel strength member supports the core, with tubes and fillers stranded around it for a compact structure. The core is wrapped with APL for moisture protection, followed by a PE inner sheath. PSP armor is applied longitudinally, and the cable is finished with a durable PE outer sheath for direct-burial environments.
Features
Has good mechanical properties and temperature characteristics.
Loose tube material itself has good water resistance and high strength.
The tube is filled with a special grease to protect the fiber.
The specially designed compact cable structure effectively prevents the casing from retracting.
PE jacket has excellent UV radiation resistance,ensure the waterproof performance of the cable.
Single wire center reinforcement core.The loose tube is filled with a special waterproof compound.
Full core filling.Plastic coated aluminum tape (APL) moisture barrier
Application
Suitable for directly buired laying method
