All cables of this group can be produced in versions (A)-HF.

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

InTube Micro cable may be produced in a dry version.

In dry version hydrophobic gel is replaced with dry water-blocking materials. This cable is easy to install.
