The tight buffered fibers which are sheathed with special buffer material to protect the fiber are stranded around the FRP(Fiber reinforced plastic),then, a layer of Aramid yarn is applied as a strength member,the cable is copleted with PVC jacket.(02-12 fiber, Stranded structure, FRP Strength member,1-fiber subunit(Φ900μm Tight buffer, Aramid yarn),PVC jacket.
