GYFTY53 Stranded Loose Tube Armored Cable
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 locates in the center of core as a
strength member. The tubes (and fillers) are stranded around the
strength member into a compact and circular core. Then the cable
core is covered with a thin polyethylene (PE) inner sheath, which
is filled with jelly to protect it from water ingress. A layer of
water-blocking material is applied around the cable core to prevent
water ingress all the same. After a corrugated steel tape armor is
applied, the cable is completed with a PE outer sheath
Characteristics
· Good mechanical and temperature performance
· High strength looes tube that is hydrolysis resistant
· Special tube filling compound ensure a critical protection of
fiber
· Crush resistance and flexibility
· 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- APL moisture barrier
- PSP enhancing moisture-proof Water-blocking materialStandard
GYTY53 cable complies with Standard YD/T 901-2001as well as IEC
60794
