Stranded Loose Tube Single-steel-wire Armored Cable GYTA53

fiber, 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. An Aluminum Polyethylene Laminate (APL) is applied around the cable core. which is filled with the filling compound to protect it from water ingress.

GYTA53-underground-cable

Feature:

1. Good mechanical and temperature performance
2. High strength loose tube that is hydrolysis resistant
3. Special tube filling compound ensures a critical protection of fiber
4. Crush resistance and flexibility
5. The following measures are taken to ensure the cable watertight:
    a. Steel wire used as the central strength member
    b. Loose tube filling compound
    c. 100% cable core filling
    d. APL moisture barrier
    e. Water-blocking material

Note:1.suffix Xn denotes fiber type and see details in FOCC's cable coding illustration

         2.the colour arrangement of fiber and tube is specified in the colour identification table.

 Fiber coloure Identification of loose tube with FOCC

the fibers in cables can be identified by standard colour identification in compliance with YD/T901-2001 Standard.

Standard colour Identification

GYTA53-underground-cable2Note: A. when the fiber count of one loose tube is less than 12, the fibers are identified form the NO.1 colour on a stream.

         B.in standard colour identification, the NO.6 white colour could be replaced by nature colour,which called standard colour identification W.
