GYXTW Armoured Fiber Optic Cable

TangHu GYXTW central bundle tube cable is constructed by inserting a 250 μm fiber into a loose tube made of a high modulus material filled with a water-repellent compound. The loose tube is coated with a double-sided plastic coated steel strip (PSP) longitudinally, and a water-blocking material is added between the steel strip and the loose tube to ensure the compactness and longitudinal water resistance of the cable. Two parallel steel wires are placed on both sides to be extruded. The vinyl sheath is cabled.
