    Description

    Use:
    For laying in 1-3 categories of soils (without cryosolic deformations), in cable-conduit lines and pipelines on bridges and pipe bridges, in tunnels, collectors at the entry into a building, including places infested with rodents, and on the exterior walls of building and structures.

     

    Design:
    Cable with a central optical module, which can contain up to 24 optical fibers. Represents simplified version of a design UТxxx-SM-03.Armour layer is made from steel goffer band, and apart from providing mechanical protection, serves as a hydrobarrier preventing moisture diffusion through polymeric coatings towards optical fiber. Water-blocking band is laid between armour and optical module. External coating is made from UV-stabilized polyethylene of high density. For additional reinforcing of construction, two strength elements are placed in external coating, they are made from steel braiding.
