GYTS Stranded Loose Tube Light-armored Cable

GYTS

Stranded Loose Tube Light-armored Cable

1. Loose Tube: thermoplastic material, containing optical fibers and filled with gel.

2. Central Strength Member(CSM): phosphate steel wire.

3. Armor: corrugated steel tape.

4. Longitudinal Water Blocking Material: Water blocking tape.

5. Cable Filling Compound.
   

6. Outer Sheath: black polyethylene.

Description

• Excellent mechanical and temperature performance guaranteed by the accurate excess fibre length

• Critical protection to fibres, based on the excellent hydrolysis resistance and strength performance of tube material and special filling compound filled in the tube

• Excellent crush resistance and flexibility

• Excellent ultraviolet prevention with PE sheath

• The following measures are taken to ensure the water blocking performance of the cable:

•     Single steel wire used as the central strength member

•     Special water-blocking filling compound in the loose tube

•     100% cable core filling

•     PSP moisture barrier
