All cables of this group can be produced in versions (A)-HF, H and (А)-FRHFLTx.

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

H — cable jacket is made of a polymer material not propagating fire in a single laying.

(A)-FRHFLTx — the cable jacket is made of a polymer material, flame retardant in a group laying, not emitting corrosive gases when burning and smoldering with low toxicity of combustion products.

The InDuct Steel Tube 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.
