SK Unitube Non-armored Cable（GYXY）
Features
•Description
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. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides. The cable is completed with a polyethylene (PE) sheath.
•Characteristics
• Good mechanical and temperature performance
• High strength loose tube that is hydrolysis resistant
• Special tube filling compound ensure a critical protection of fiber
• Two parallel steel wires ensure tensile strength
• PE sheath protects cable from ultraviolet radiation
• Small diameter, light weight and friendly installation
• Long delivery length
•Standards
GYXY cable complies with Standard YD/T 769-2003.
