The fibers, ∅250µm colored fibers, 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 PE for cable with high fiber count, locates in the center of
core as metallic strength member. Tubes (and fillers) are stranded
around the strength member into a compact and circular cable core.
An Aluminum Ployethylene Laminate (APL) is applied around the cable
core. Then the cable core is covered with a thin flame-retardant
inner sheath, which is filled with jelly to protect it from water
ingress. Ater a corrugated steel tape armor is applied, the cable
is completed with a flame-retardant outer sheath.
Features:
- Good mechanical and temperature performance and flame-retardant
property;
- High strength loose 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 water tight:
steel wire used as central strength member; 100% cable core
filling; loose tube filling compound; APL moisture barrier; PSP
enhancing moisture barrier; Water-blocking material.
