Description
● GYDTA Stranded Loose Tube Aluminum Armored Fiber Ribbon Cable:
The structure of GYDTA optical cable is to put 4, 6, 8, 12 core optical fiber ribbon into loose tubes made of high modulus material, and the loose tubes are filled with waterproof compound. The center of the cable core is a metal reinforced core. For some optical fiber cables, a layer of polyethylene (PE) needs to be extruded outside the metal reinforced core. The loose tubes and the filler ropes are twisted around the central reinforcing core to form a compact and round cable core, and the gaps in the cable cores are filled with water blocking fillers. The Aluminum tape (PSP) is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.
● Features:
►Good mechanical properties and temperature characteristics;
►The loose tube material itself has good hydrolysis resistance and high strength;
►The tube is filled with special grease to protect the optical fiber critically;
►Specially designed compact optical cable structure effectively prevents the casing from retracting;
►Good pressure resistance and flexibility;
►PE jacket has good resistance to ultraviolet radiation;
►Adopt 4, 6, 8, 12 core optical fiber ribbon, flexible application;
►Use the following measures to ensure the waterproof performance of the optical cable:
-Single steel wire center reinforced core
-Loose casing filled with special waterproof compound
-Complete cable filling
-Aluminum tape improves the moisture resistance of optical cable
►Complies with Standard YD/T 981.3 and IEC 60794-1 standards.
● Application:
►Aerial/conduit;
►Connecting communication equipment;
►Indoor shaft, buildings, pipe, buried.
