 Co-axial Cables
 
Co-axial cables are also known as Radio frequency cables. These are produced with specific raw materials & strict dimensions & design control for accurate impedance, capacitance & attenuation losses etc. Normally used in RADIO FREQUENCY APPLICATIONS SUCH AS ANTENNAS AND VIDEO TRANSMISSIONS.
 
  • Conductor : Annealed Plain/Tinned/Silver Plated/CCS Wires
  • Insulation : Foam/PTFE/Solid Polyethylene.
  • Shield : Annealed Plain/Tinned Copper
  • Outer Sheath : PVC/PTFE
  • Temperature Range : -20 °C to +85 °C
