PTCL Cables offer ADSS (All Dielectric Self-Supporting) Aerial Optical Fiber Cables. ADSS Optical Fiber Cables are solution for High Performance Aerial Environments including Power Transmission and Distribution Networks. All-Dielectric Construction reduces installation costs by avoiding the need for expensive cable shielding and grounding.



    Aerial Installation - Lightening Protection - Junction Communication System, Subscriber Network System        


Cable Constructions:      

   Loose Tube Filled With Gel-Stranded around Central Strength Member - Dry Core - Core Wrap - Water Blocking Material - Polyethylene Inner Sheath - Peripheral Strength Member (Layer of Aramid Yarn) - Polyethylene Outer Jacket


Technical Characteristics

  • The unique extruding technology provides the fibers in the tube with good flexibility and bending endurance
  • The unique fiber excess length control method provides the cable with excellent mechanical and environmental properties
  • Multiple water blocking material filling provides dual water blocking function
  • Provides good crush resistance
