Stranded Layer Non Armored Ribbon Fiber GYFDTA
GYFDTA uses FRP as the central strength member ensures good tensile resistance,and improves the bending performance.The middle layer of aramid yarn increases the tensile strength of the cable. It has excellent moisture resistance ability:the loose tube is filled with grease to protect the fiber, APL tape prevent the water ingress, then the cable is completed with PE out sheath. It's suitable for aerial and duct application. Because of the good moisture resistance, it can also be used in cable trench. It has the loose tube structure with ribbon cable, which is surrounded by the APL tape. GYFDTA is a good option for interoffice communication,outdoor access network
