Distribution 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.

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.
