描述
The fibers, 250μm, are positioned in aloose tube made of a high modulusplastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) is located in the centerof core as a non-metallic strength member.The tubes (and fillers) are strandedaround the strength member into acompact and circular core. An aluminumPolyethylene Laminate (APL) is appliedaround the cable core. Then the cablecore is covered with a thin polyethylene(PE) inner sheath, which is filled withjelly to protect it from water ingress.After a corrugated steel tape armor isapplied, the cable is completed with aPE outer sheath.
