The fibres are positioned in a loose tube made of a high modulus plastic. Tubes are filled with a filling compound. Fibres can move inside the tube. Tubes are stranded around the strength member into a compact and circular cable core. The cable is completed with a polyethylene sheath.
Main characters of YOFC stranded loose tube cable:
－High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fibres.
－The strength member is located in the center of the cable core. The loose tubes are stranded around the strength member at proper lay length. The tensile strength and temperature performance of cable can be ensured by controlling the fibre excess length and adjusting the lay length.
－The spaces between loose tubes and strength member are filled with cable filling compound to prevent water ingress.
－Various measures are taken to ensure the cable watertight longitudinally and axially.
－Various measures are taken to ensure the crush-resistance of the cable according to different requirements.
