Description
The fibers, 250um, are positioned in a loose tube made of a high modulus plastic.
The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic(FRP)locates in the center of core sa a non-metallic strength member. The tubes(and fillers)are stranded around the strength member into a compact and circular core.
After the cable core is filled with the filling compound,it is covered with thin PE(polyethlyene)inner sheath. Then a layer of aramid yarn is applied as additional strength member
and the cable is completed with a polyethylene(PE)outer sheath.
Characteristics
Good mechanical and temperature performance
Aramid yarn strength member ensures good performance of tensile strength
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Crush resistance and flexibility
The following measures are taken to ensure the cable watertight
Single Fiber Reinforced Plastic as the central strength member
Loose tube filling compound
100% cable core filling
