Steel Tape STA Low Smoke Zero Halogen Cable Class 2 conductor N2X2Y


Application


  1. Flame-retardant low-smoke zero-halogen (LSZH/LSOH) cables are widely applied in various critical scenarios due to their enhanced safety and environmental features:
  2. Transportation Systems:Deployed in metro systems, light rail transit, and aviation facilities to ensure safe power transmission while minimizing toxic emissions during fire incidents
  3. Public Infrastructure: Used in hospitals, schools, high-rise buildings, and commercial complexes to reduce smoke and hazardous gas release, aiding evacuation and firefighting
  4. Industrial Facilities:Installed in petrochemical plants, mining operations, and power stations where fire risks demand cables with superior flame resistance and minimal corrosive combustion byproducts
  5. Energy and Utilities:Employed in nuclear power plants, transformer stations, and electrical distribution systems to maintain operational integrity under extreme conditions
  6. Confined Public Spaces:Utilized in air-handling spaces (e.g., ceilings, raised floors) of airports, subway stations, and office buildings to restrict smoke spread and improve visibility during emergencies

Construction


  1. Conductor :Class 2 stranded copper conductor
  2. Insulation :XLPE (Cross-Linked Polyethylene)
  3. Bedding :LSZH (Low Smoke Zero Halogen)
  4. Armour :STA (Steel Tape Armour)
  5. Sheath :LSZH (Low Smoke Zero Halogen)
