1.1The steel wire strand provides extremely high tensile strength, facilitating self-supporting aerial installation and reducing installation costs.
2.The cable exhibits excellent mechanical properties and temperature characteristics.
3.The loose tube material itself possesses good hydrolysis resistance and high strength.
4.The tubes are filled with a special thixotropic jelly, providing critical protection for the fibers.
5.The following measures ensure the cable''''''''s water resistance:
Filling the loose tubes with a special waterproof compound.
Fully filling the cable core.
A moisture barrier of plastic-coated aluminum tape (APL).
