GYTA Loose Sheathed Twisted Aluminum Tape Armored Optical Cable
The structure of GYTA optical cable is to put 250 µ m optical fiber into the loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The center of the cable core is a metal reinforced core. For optical cables with certain number of cores, a layer of polyethylene (PE) shall be extruded outside the metal reinforced core. The loose tube (and filler rope) is twisted around the central reinforced core to form a compact and round cable core, and the gap in the cable core is filled with water blocking filler. Plastic coated aluminum tape (APL) is longitudinally wrapped and then extruded with polyethylene sheath to form cable.
Characteristics:
Good mechanical properties and temperature characteristics
Loose tube material itself has good hydrolysis resistance and high strength
The tube is filled with special ointment, which provides critical protection for optical fiber
The specially designed compact optical cable structure effectively prevents the sleeve from retracting
PE sheath has good ultraviolet radiation resistance
The following measures shall be taken to ensure the waterproof performance of optical cables:
Single steel wire central reinforcing core
The loose tube is filled with special waterproof compound
Full core filling
Plastic coated aluminum strip (APL) damp proof course
