Outdoor Armored Cable High Modulus Plastic Loose Tube GYFTA53
Description
The 250μm fibers are housed in a high modulus plastic loose tube filled with a water-resistant compound.
A non-metallic FRP core serves as the central strength member, around which the tubes and fillers are
stranded to form a compact circular core. An APL layer shields the core from water, followed by a thin PE
inner sheath. Kevlar yarn enhances tensile strength, covered by a PSP layer, and finalized with a PE outer
sheath.
Application
1 Ideal for outdoor deployment, including direct burial installations.
2 Suitable for trunk power transmission systems.
3 Designed for access and local networks in high electromagnetic interference areas.
Characteristic
1 Excellent mechanical and temperature resilience.
2 Specialized tube filling compound ensures vital fiber protection.
3 Balances crush resistance with flexibility.
4 PSP layer enhances moisture resistance for added durability.
