Stranded Loose Tube Mining Flame-retardant Cable（MGTS）
Details:
Stranded Loose Tube Mining
Flame-retardant Cable（MGTS）
Description
The fibers, 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 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. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a flame-retardant sheath.
Characteristics
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Specially designed compact structure is good at preventing loose tubes from shrinking
Crush resistance and flexibility
Special sheath material ensures excellent flame-retardant performance
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
PSP enhancing moisture-proof
Standards
MGTS cable complies with Standard YD/T 901-2001 as well as MT386-1995; and passes MA certification.
Application: Duct /Aerial /Direct buried
