The fibres are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. A fibre reinforce plastic locates in the center of core as a non-metallic strength member. The tubes(and the fillers) are stranded around the strength member into a compact and circular core. After the cable core is filled with the filling compound to protect it from water ingress. The cable is completed with a PE(LSZH) sheath.
Installation
Duct, Non self-supporting aerial
Characteristics
1.Excellent mechanical and temperature performance.
2.Special tube filling compound ensure a critical protection of fibre and resist the water.
3.100% core filling water prevent cable jelly to ensure the cable watertight.
4.Single FRP as the central strength member to withstand axial loads.
5.Outer sheath protects cable from ultraviolet radiation.
