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.
