Loose sheath layer stranded single fine round steel wire armored optical cable (GYTA53 + 33)
The structure of GYTA53+33 optical cable is that the 250 μ M optical fiber is sheathed in 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. The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact and circular cable core. The gap in the cable core is filled with water blocking filler. A layer of polyethylene inner sheath is extruded after longitudinal wrapping of plastic coated aluminum strip (APL), and polyethylene outer sheath is extruded after longitudinal wrapping of double-sided plastic coated steel strip (PSP). After being armored by single fine round steel wire, the PE outer sheath is extruded to form cable.
Product standards
GYTA53 optical cable meets YD / T 901 and IEC 60794-1 standards.
Product features
It has good mechanical properties and temperature characteristics
The single fine round steel wire armor makes the optical cable have stronger tensile properties
Loose tube material itself has good hydrolysis resistance and high strength
The tube is filled with special ointment to protect the optical fiber
Good compression resistance and softness
The following measures shall be taken to ensure the waterproof performance of the optical cable:
-Reinforced core of single steel wire center
-The loose tube is filled with special waterproof compound
-Full core filling
-Plastic coated aluminum strip (APL) damp proof course
-Double side plastic coated steel strip (PSP) improves moisture resistance of optical cable
-Good water blocking material to prevent longitudinal water seepage of optical cable
Application: directly buried, climbing, underwater
