Application

These cables are applied for fixed indoor and outdoor installation. Suitable for direct laying in ground, also resistant to UV-irradiation. They can also be laid in dry and damp environment, on or under plaster, on cable trays, same as in walls and concrete. Resistant to water sprinkling, but not intended for immersion in water. Suitable for medium mechanical loads, and specially for installations requiring increased flexibility. Suitable for electric installations with marked fire-fighting and function preserving requirements, for alarm systems, fire sensors, evacuation elevators and other supply systems in case of 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. It is important that these cables should not be laid on common trays, but on fire resistant trays, which retain their geometry in case of fire. Keeping the 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
– easier handling and installation due to high flexibility
– possible direct laying in ground and exposure to UV-irradiation
