GYTA53+333 underwater cable

Fiber count: 2-216 cores
Product description:
Put single or multi-mode optic fiber into loose tube made by high-module polyester material and fill tube with waterproof compound; core of cable is consisted of one metal strength core, PE may need to be painted on metal strength core for optic cables at certain cores; loose tube (and filler) shall be stranded with strength core into tight round cable core, cable core shall be filled with water-blocking fillers; APL shall be longitudinally folded and extruded into cable with polyethylene sheath. PSP shall be longitudinally folded and extruded into cable with outer sheath. Then, such cables shall be finally extruded into cable with polyethylene outer sheath after armoring with single or double small circle steel wire.
Execution standard:
YD/T901-2009 stranded outdoor communication optic cable
Laying method: pipe, direct bury
Application scope: remote communication and inter-unit communication.
Product characteristics:
Double small round armoring enables higher tensile property of cables
Good mechanical performance and temperature property
Material of loose tube compromises water resistance property and higher strength.
Tubes are filled with certain pates to conduct critical protection on optic fibers
Good pressure resistance and flexibility
Following measures may be applied to maintain waterproof performance of optic cables:
-Single steel wire strengthen core
-Fill loose tube with special waterproof compound
-Fully fill cable core
-Good water blocking material prevents longitudinal water leakage on cables
-Paint PSP dampproof coat on both surfaces
-PSP improves penetration resistance property of cables
