Fiber Optic Cable with 8 Shape Self Supporting Messenger GYTC8S
Descripción
Product description
The structure of the GYTC8S cable is to insert a 250 μm fiber into a loose tube made of a high modulus material, and the loose tube is filled with a waterproof compound. The center of the core is a metal reinforcing core (also non-metallic, such as FRP, etc.), and the loose tube (and filling rope) is twisted around the center reinforcing core into a compact circular core. In the form of a longitudinal package, a layer of plastic coated aluminum tape (APL) is placed inside the sheath outside the core, and finally a polyethylene sheath is extruded together with the steel strand to make the cross section “8” shaped.
Features
·Steel wire strands have extremely high tensile strength, which is convenient for self-supporting overhead laying and reduces installation costs.
·Good mechanical properties and temperature characteristics.
·The loose tube material itself has good water resistance and high strength.
·The tube is filled with a special grease to provide critical protection to the fiber.
·The following measures are taken to ensure the waterproof performance of the cable.
·The loose tube is filled with special waterproof compound.
·Filling the whole cross-sectional cable core.
·Double coated steel strip (PSP) moisture barrier.
Product Standards
·GYTC8S cable complies with YD/T1155-2011 and IEC60794-1 standards.
