Outdoor Use With Anti-Rodent Protection For Direct Burial GYFTY53
Description
The cable structure involves fibers housed in a high-strength plastic tube, filled with a water-resistant compound.
At the core, a fiber reinforced plastic (FRP), sometimes encased in polyethylene (PE) for high fiber count cables,
acts as a dielectric strength member. Tubes and fillers are wrapped around this strength member, forming a co-
mpact circular core. This core is shielded from water penetration by a water-blocking tape, covered with a thin
PE inner sheath. Following this, a PSP layer is longitudinally applied over the inner sheath, and the cable is fina-
lized with a PE outer sheath for added protection.
Application
★ Designed for outdoor distribution and direct burial, ensuring durability in various conditions.
★ Tailored for trunk power transmission systems, optimizing energy transfer efficiency.
★ Ideal for access and local networks in areas with high electromagnetic interference, ensuring reliable connectivity
amidst challenging environments.
Characteristic
1 Robust mechanical resilience and temperature stability.
2 Hydrolysis-resistant high-strength loose tube construction.
3 Critical fiber protection ensured by a specialized tube filling compound.
4 Balances crush resistance with flexibility for versatile use.
5 Fully filled cable core with loose tube filling compound for enhanced protection.
6 PSP layer bolstering moisture resistance for added durability.
