Detailed introduction

· Product Description

The fibers, 250μm, are positioned in a loose tube made of a high modulus material. The tubes are filled with a water-resistant filling compound. The loose tube is longitudinally covered with a double-sided plastic steel strip (PSP). A water-blocking material is placed between the steel strip and the loose tube to ensure the compact and longitudinally water-blocking cable. Two parallel steel wires are placed on both sides of the cable and then the cable is squeezed into a polyethylene sheath.

· Product Features

· Good mechanical and temperature properties · The loose tube material itself has good hydrolysis resistance and high strength

· Special oil is filled in the tube to protect the optical fiber

· Good compression resistance and softness

· Double-coated plastic steel strip (PSP) improves the cable's moisture resistance

· Two parallel wires ensure the tensile strength of the cable

· Small diameter, light weight and easy to lay

· Longer delivery length

· Product standards

GYXTW cable complies with YD/T 769-2003 standard
