GYTY53 Cable The Fibers, 250m,are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound.A steel wire locates in the center of core as a metallic strength member. , sometimes ,the metal strength member will be packed by PE jacket .loose tube ( and fillers ) are stranded around the central strength member into a compact and circular cable core which is filled by the waterproof compound and packed by PVC jacket and PSP to extrude into a cable .
Characteristics
Good mechanical and temperature properties
The loose tube has good water resistance and high tensile strength
Special cream fill the loose tube to provide key protection to the fiber
Good crush resistance and flexibility
To ensure the water resistance by :
Single steel wire central strength core
Inside the loose tube , fill the special water proof chemical compound
PSP enhance the cable water resistance
Good water blocking materials to avoid water penetration
