CABLES AND WIRES - Novkabel

Halogen-free flame retardant materialsThe statistics have recorded a significant numberof fires caused by the adverse events on electricalinstallations.Studies have shown that the fire in buildings androoms has often been transmitted via cables. Thisfact was of crucial significance for the measurestaken to prevent the fire from spreading or, incase of spreading, to prevent it from spreading viacables, thus reducing the negative consequencesfor people, property or environment.The following table contains the literary data ontoxic compounds and smoke density in thecombustion products for certain materials used incable industry:University of Radnički, Novi SadTable: Comparative values of combustion productsMaterial CO NO X SO 2 HCN HClDensity ofsmoke DmPVC 1500 < 5 < 5 < 3 600 x 10 3 600XLPE 200 < 1 < 1 < 1 < 1 90EPR 100 < 1 < 1 < 1 < 1 75Regulation * < 3000 < 50 < 50 < 100 < 50 -* Method NES 713, values in ppm after 1.5 min.The cables made of halogen free flame retardant materials (HFFR) with improved properties orimproved properties and insulating functionality in case of fire are intended for the following:- signal systems for fire detection and alarm systems,- security lighting systems,- general purpose.210The installation of HFFR cables provides low fire load without flame transmission via cables.Low density of smoke released by fire allows people to find their way out more easily.Combustion products are not toxic since they do not contain halogen elements in theirstructure.HFFR cables are appropriate for use in buildings and facilities receiving a lot of people orcontaining valuable equipment, such as:- residential and commercial buildings,- theaters, cinemas, night-clubs,- hospitals, schools, hotels,- shopping malls, subways,- banks, museums, galleries,- computer centers, telephoneexchange,- power plants, command and controlcenters,- sport facilities, distributive centersArena Sport Center, Belgradeetc.
