LV (0,6/1 kV) power cables with XLPE insulation and HFFR sheath with concentric conductor

AXCMK-HF

APPLICATION

Power cable suitable for fixed installation in dry and damp environment, on or under plaster, on cable trays, same as in walls and concrete. Not intended for direct laying in ground or water. For outdoor application can be laid in tubes, but in that case should be taken all precautionary measures necessary to prevent water penetration into the tubes. Suitable for supply systems in an emergency. Appropriate for application in all situations where people and material goods need to be protected in case of fire. 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. Concentric conductor serves as electromagnetic screen, which could be applied as neutral conductor too.
advantages: 
- halogen-free, no release of toxic or corrosive gases under fire
- reduced smoke occurrence under fire 
- no flame propagation in vertical cable bundle
