Shanghai Gengyun Industrial Co., Ltd
The structure of No.T-FC090 GYTA53+33 underwater fiber cable is to insert 250 µ m optical fiber into a loose tube made of high modulus material, and fill the loose tube with waterproof compound. The center of the cable core is a metal reinforced core, and a loose sleeve (and filling rope) is twisted around the center reinforced core to form a compact and circular cable core. The gaps inside the cable core filled with waterproof fillers. After being longitudinally wrapped with plastic coated aluminum strip (APL), a layer of polyethylene inner sheath extruded, and after being longitudinally wrapped with double-sided plastic coated steel strip (PSP), a polyethylene outer sheath extruded. After being armored with a single thin round steel wire, a polyethylene outer protective layer is finally extruded to form the cable.
Standard
Meet YD/T 901 and IEC 60794-1 .
Application
Underwater cables used in the telecommunications industry and offshore oil and gas industry. In addition, they also used in marine observation networks, local area networks (LANs), video, data, CATV and inter-office communication applications.
Product Feature
1. Single steel wire center reinforcement core;
2. Fill the loose tube with special waterproof compound;
3. Complete cable core filling;
4. Plastic coated aluminum strip (APL) moisture-proof layer;
5. Double sided coated steel strip (PSP) improves the moisture resistance of optical cables;
6. Good water blocking materials to prevent longitudinal water seepage in optical cables;
7. Underwater fiber cable has excellent mechanical properties and temperature characteristics;
8. Single fine round steel wire armor enhances the tensile performance of optical cables;
9. The loose tube material itself has good hydrolysis resistance and high strength;
10.The tube is filled with special ointment to provide critical protection for the optical fiber;
11.Good compression resistance and flexibility;
12.Ensure the waterproof performance of the optical cable;
