Non-metallic Strength Member Single Armored Cable – GYFTY53

Central Strength Member is FRP

Cable Structure:

Tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of the core as a non-metallic strength member. Tubes and fillers are stranded around the strength member into a compact and circular cable core. Then the cable core is covered with a thin PE inner sheath, which is filled with jelly to protect it from water ingress. A layer of water-blocking material is applied around the cable core to prevent water ingress all the same. After a corrugated steel armor is applied, the cable is completed with a PE sheath.
