Description:
The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tube are filled with a water-resistant filling compound. The tube is wrapped with a layer . The loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel FRP wires are placed at the two side of the steel tape. The cable is completed with a polyethylene(PE) sheath.
Characteristics:
Good mechanical and temperature performance.
High strength loose tube that is hydrolysis resistant.
Special tube filling compound ensure a critical protection of fiber.
Crush resistance and flexibility.
PSP enhancing moisture-proof.
Two parallel steel wires ensure tensile strength
Small diameter, light weight and friendly installation
Long delivery length
Application:duct/aerial
