Halogen-free installation cable suitable for application in household and industry, in facilities where human lives or valuable property need to be protected against damages caused by fire. Used as halogen-free alternative to NYM cable. Recommended for public buildings frequented by a lot of people, and for buildings of high material value, for industrial complexes, electric power plants, transformer stations, municipal facilities, hotels, shopping malls, hospitals, schools, airports, underground railways and similar. Laid in, on or under plaster, in walls or in concrete, directly or in cable canals, without special mechanical protection, but not in dry or prestressed concrete. Suitable for dry, damp or wet environment, for internal or outdoor application (only if the cable is protected against direct sunlight).

advantages:
- halogen-free, no release of toxic or corrosive gases under fire
- reduced smoke occurrence under fire
- no flame propagation in vertical cable bundle
