Description
Air-blowing micro cable (GYFTY) is housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member and surrounded with dry water-blocking material to form a cable core. An extremely thin outer PE sheath is extruded outside the core.
