Duct & Aerial Cable

Stranded Loose Tube Non-armored Cable GYTA/S

The fibres, 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 fibre 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) or PSP is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath.

    Characteristics

    Good mechanical and temperature performance

    High strength loose tube that is hydrolysis resistant

    Special tube filling compound ensure a critical protection of fibre

    Specially designed compact structure is good at preventing loose tubes from shrinking

    PE sheath protects cable from ultraviolet radiations

    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 or PSP moisture barrier

    Standards

    GYTA/s  cable complies with Standard YD/T 901 as well as IEC 60794-1.

    Note: 

    a. Suffix Xn denotes fibre type

    b. The colour arrangements of fibre and tube are specified in the colour identification table

    c. The cable shouldn‘t store in outdoor environment more than 6 months in order to keep the cable reel good state
