Standards and Norms

  • UL 444 Communications Cables
  • UL 1655 Community Antenna Television Cable
  • NEC Article 725 Remote-Control, Signaling, and Power-Limited Circuits
  • NFPA 70 National Electrical Code
Conductor
  • Copper: High electrical conductivity and good mechanical properties
  • CCS (Copper-Clad Steel): Higher mechanical strength
  • Skin effect: Same performance as solid copper at high frequencies
Insulation
  • Foamed polyethylene (SFS) with lower dielectric losses
  • Better suited for long distances
  • Chemical or physical foaming (nitrogen injection)
Jacket
  • Flame-retardant Polyvinyl Chloride (PVC)
  • Good flexibility and resistance to chemical agents
  • Abrasion resistant
Shielding
  • Double shielding: Aluminum tape + Aluminum braid
  • Shielding effectiveness depends on coverage percentage
  • Higher coverage = Higher effectiveness
