Fireproof, halogen-free telecommunication cables are intended for use in emergency lighting systems, alarm systems, signaling systems, teletransmission systems, sound warning systems (DSO), as well as in fire alarm and fire automation systems and in other circuits ensuring safety. The static shield (ekw) protects the cables against the influence of external magnetic fields. In fire conditions, these cables ensure the proper functioning of the installation for at least 90 minutes. (PH90) and cable insulation durability for 3 hours (FE180). During combustion, they do not emit toxic gases or dense smoke. The cables are suitable for permanent installation inside buildings. HTKSHekw FE180/PH90 (E90) cables have been tested in accordance with the requirements of DIN 4102 part 12 and can be installed in E90 cable routes as part of the E90 cable assembly (assembly on brackets every 30 or 60 c
