Riser with Micro Tubes

Applied inside buildings (including vertical runs), in trays, channels, on outer sides of buildings, as well as in duct, in tubes and blocks. Suitable for blowing-in into protecting polyethylene tubes.

Applied in ducts, trays, blocks, tunnels, and collecting channels in protecting tubes.

Also applied for aerial installation power lines, lamp posts, between buildings and constructions. Suitable for aerial installation on transmission equipment and power facilities.

Advantages

Perfect solution for high buildings: a separate micro loose tube is guided to every inter-floor box. With 100% penetration, the number of micro loose tubes equals to the number of floors, the number of fibers equals to the number of flats on the floor.

Operation temperature down to -30C.

Easy access to the fiber at any place of the cable

Flame-retardant

UV-resistant

All-dielectric construction

Resistance to crushing loads – 80-200 N/cm.

Allowable tensile strength up to 400 N.

High density of fibers makes it possible to bundle up to 24 fibers into micro loose tubes and place up to 48 micro loose tubes in a cable.

Options

Local cables can be produced in versions ng(A)-HF and ng(А)-HFLTx.


ng(A)-HF — cable jacket is made of a polymer material, flame retardant in a group laying, with low smoke emission, halogen-free (Class PRGP1).


ng(A)-HFLTx — the cable jacket is made of a polymer material, flame retardant in a group laying with low toxicity of combustion products.
