Description
Stranded loose tube double armored and double sheathed cable (GYTA53) construction is that 250um fibers are positioned in a loose tube which is made of high modulus plastic and 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 are stranded around the strength member into a compact and circular cable core; The APL (Aluminum Tape) is longitudinally applied over the cable core which is filled with the filling compound to protect it from water ingress and then the cable core is covered with a polyethylene (PE) inner sheath; After the PSP (Steel Tape) is longitudinally applied over the inner sheath, the cable is completed with a polyethylene (PE) outer sheath.
Standards
Stranded loose tube double armored and double sheathed cable (GYTA53) complies with standard YD/T901 and IEC60794-1
