GYXTZY type armored cable, indoor/outdoor, нг(А)-HF jacket
Used for laying in the ground, including swamps and shallow non-navigable rivers, cabling in cable ducts, pipes, trays, tunnels, collectors, over bridges and overpasses, between buildings, and inside buildings.
Design
The cable contains a central optical module with loosely laid fibers. The free space in the optical module is filled with a hydrophobic gel. Steel wire armor is spirally covered over the central optical module. The free space between the wires is filled with a hydrophobic gel. The armor is covered with a jacket made a flame retardant, halogen free, low smoke emission, resistant to UV radiation polymer composition.
