It has good mechanical properties and temperature characteristics.
The loose tube material itself has good hydrolysis resistance and high strength
The tube is filled with special oil sound, which provides key protection for the optical fiber.
The specially designed tight cable structure effectively prevents the tube from shrinking.
It has good pressure resistance and softness.
The PE sheath has good resistance to ultraviolet radiation.
GYXTW: Central bundle tube type, two parallel steel wire structure to ensure the tensile strength of the optical cable: strong anti-lateral pressure ability.
GYTA: Layer twisted structure, single steel wire center reinforcement core, loose tube filled with special waterproof compound, complete cable core filling, double-sided plastic coating (PSP) to ensure the waterproof performance of the optical cable.
