GYXTC8S
GYXTC8S fiber optic cable is structured to insert 250 microns of optical fiber into loose sleeves made of high-modulus materials, which are filled with waterproof compounds At the center of the core is a metal reinforced core (or non-metallic, such as FRP, etc ), the loose sleeve (and filling rope) is twisted around the central reinforced core to form a compact circular core A layer of plastic-coated aluminum strip (APL) is added to the outer sheath of the cable core and inner sheath of the cable core in the form of longitudinal package At last, the polyethylene sheath is extruded together with the steel strand to make its section "8 "
- Product introduction
·Product features
• steel wire strand has extremely high tensile strength, which facilitates self-supporting overhead laying and reduces installation cost
• excellent mechanical properties and temperature characteristics
• the loose casing material itself has good water resistance and high strength
• the tube is filled with special ointment, which provides critical protection for the optical fiber
• adopt the following measures to ensure the waterproof performance of optical cables
• loose sleeve filled with special waterproof compounds
• full section filling of cable core
• double-sided coated plastic steel belt (PSP) moisture-proof layer
·Product standards
GYXTC8S cable follows YD/ t1155-2011 and iec60794-1 standards.
