Local cables can be produced in versions (A)-HF, (А)- HFLTx 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 (Class PRGP1).

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