GYFTY cable
For GYFTY cable, 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. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. After the cable core is filled with the filling compound to protect it from water ingress, the cable is completed with a PE sheath.
Features:
Full cross-section water-blocking structure to ensure good water blocking and moisture resistance
Loose tube is filled with special ointment for a key fiber protection
High-modulus glass fibre reinforced plastics (FRP) central strength member
With all-dielectric (non-metallic) structure, and light weight, the fiber is convenient for laying, excellent in anti-electromagnetic capacity, and applicable to power system and multi-thunder area.
Applications:
Suitable for long-distance communication and indoor communications
