描述
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 locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.
产品特性
·High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost.
·Good mechanical and temperature performance
·High strength loose tube that is hydrolysis resistant
·特殊的管内填充化合物可确保对纤维的关键保护
·The following measures are taken to ensure the cable watertight:
·Loose tube filling compound
·100% cable core filling
·APL moisture barrier
Product Standard
·GGYTC8A cable complies with Standard YD/T 1155-2011 as well as IEC 60794-1.
