GYTA33 Underwater steel wire armored optical cable


The structure of GYTA33 optical cable is based on the structure of GYTA optical cable, which strengthens the waterproof function and anti-extrusion function. The optical fiber is sheathed in a loose tube made of PE material, and the tube is filled with waterproof compound. The center of the cable core is a metal reinforced core. For some optical cables with several cores, a polyethylene (PE) sheath needs to be extruded outside the metal reinforced core. The loose tube is twisted around the central reinforcement to form a compact circular cable core, and the gaps in the cable core are filled with water-blocking fillers. After being coated with aluminum tape, a layer of PE inner sheath is extruded, and then a single layer or a double layer of thin round steel wire armor is longitudinally wrapped, and finally a polyethylene outer sheath is extruded to form a cable.
