Gen. to CT 2243.
CONSTRUCTION
Micromodules: the fibers are grouped in a micro-structure (group of fibers inside of
a thin-walled tube) of 6 or 12 fibers with filling compound inside and a maximum diameter of 1.4 mm. The identification of the fibres and the micromodule is effected by means of colors in accordance with Tables 1 and 2.
Core: The micro-modules are grouped inside without any central reinforcing element.
Water blocking elements: Sweallable yarns and tapes to avoid water penetration
and make the cable waterproof.
Reinforcing elements: Aramid Yarns or fiberglass and reinforcing elements (FRP) embedded in the outer sheath.
Outer sheath: High density Polyethylene (HDPE), UV resistant with a rip cord and three green bands.
Sheath marking : The cable sheath will be marked with white ink at regular intervals with the following information:
o Manufacturing year / CABLESCOM/ cable identification/ owner + length markings
o Other sheath marks available upon request
