KPSng(А)-FRHF cable

Fire resistant cables KPSng(А)-FRHF cable

Construction details:

KPS — fire alert system cable
ng — does not sustain combustion
(А) — construction category in terms of fire safety parameters
FR — Fire Resistant, not sustaining combustion (FE 180)
HF — Halogen Free, does not emit halogens and corrosion fires in smouldering and combustion

Aapplication

For bunched wiring with regard to the volume of combustible material volume in premises with computer and microprocessor equipment; in crowded buildings and structures. Short contact with mineral oil ans gasoline is possible.

Laying and operation conditions:

  • for laying in fire protection systems (fire alert systems), alert and evacuation management systems, automated fire extinguishing systems, smoke protection systems and other systems that should sustain operation in fire).
  • for internal and external operation subject to protection from direct sunlight and fallout.
  • minimal permissible bend radius in the course of installation is 10 maximum outer diameters of the cable.
  • can be used in fire-hazardous and explosion-hazardous areas of any class.
  • shielded cables are used in buildings and structures with a high level of electromagnetic interference.
  • cables must be resistant to ambient temperatures from minus 50°C to plus 80°C and to high humidity up to 98% at temperatures up to 35°C.
  • the service life of cables in fixed installation conditions, provided that the consumer complies with the requirements for transportation, storage conditions, laying (installation) and operation, is at least 20 years.
