The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are flled with a water-resistant flling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The parallel steel wires are placed at the two sides tape. The cable is completed with a polyethylene (PE) sheath.
Description
The fibers, 250μm, are positioned in a loose tube made of a high modulus
plastic. The tubes are filled with a water-resistant filling compound. A steel
wire, sometimes sheathed with polyethylene (PE) for cable with high fiber
count, locates in the center of core as a metallic strength member. Tubes
(and fillers) are stranded around the strength member into a compact and
circular cable core. The PSP is longitudinally applied over the cable core,
witch is filled with the filling compound to protect it from water ingress.
Then, the cable is completed with a 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
Special designed compact structure is good at preventing loose
tubes from shrinking
Crush resistance and flexibility
PE sheath protects cable from ultraviolet radiation
The following measures are taken to ensure
the cable watertight:
Steel wire used as the central strength member
Loose tube filling compound
100% cable core filling
PSP enhancing moisture-proof
Application: duct/aerial/direct buride
Standards
INGO GYTS cable complies with standard YD/T901-2001
as well as IEC60794-1
