The bers, 250m,are positioned in a loose tube made of a high modulus plastic. The tubes are lled with a water-resistant Ring compound.A steel wire, sometimes sheathed with polyethylene (PE) for cable with high ber count, locates in the center of core as a metallic strength member. Tubes (and Hers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core, which is Iled with the Ring compound to product it from water ingress. The cable is completed with a ame一retardant sheath.
Description
Features
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube Iling compound ensure a critical protection of ber
Special sheath material ensure excellent ame-retardant performance
Crush resistance and exibility
Special designed compact structure is good at preventing loose tubes from shrinking
The following measures are taken to ensure the cable watertight:
1.Steel wire used as the central strength member
2.Loose tube luing compound
3.100% cable core Iling
4.PSP enhancing moisture-proof
5.Water-blocking material
