| 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. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath. 
 Features:
   ◆Good mechanical and temperature performance ◆High strength loose tube that is hydrolysis resistant ◆Special tube filling compound ensure a critical protection of fiber ◆Crush resistance and flexibility ◆PSP enhancing moisture-proof ◆Two parallel steel wires ensure tensile strength ◆Small diameter, light weight and friendly installation ◆Long delivery length     Standards:   GYXTW cable complies with Standard YD/T 769-2003.     Optical Characteristics:
