NHXCH FE180/E30

Application

NHXH cables 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 electric installations with marked fire-fighting and function preserving requirements, for alarm systems, fire sensors, evacuation elevators and other 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. Important – NHXH cables should not be laid on common trays, but on fire-resistant trays which retain their geometry in case of fire. Keeping NHXH cables in the same position in case of fire, enables additional protection of cable conductivity, by means of the mineral layer discharged around the cable at increased temperature.

advantages:
– halogen-free, no release of toxic or corrosive gases under fire
– reduced smoke occurrence under fire
– no flame propagation in vertical cable bundle
– preserved electric function of the system within set time period
