MIL-DTL-17 Coaxial Cables A Tensolite coaxial cable is a transmission line in which one conductor is centered inside and insulated from an outer flexible metal braid that serves as the second outer conductor. The basic dielectric material for coaxial cables supplied by Tensolite is PTFE because of its electrical and mechanical performance. Some attractive properties of PTFE are extremely low loss, high dielectric strength, no measurable water absorption, and electrical efficiency at both high and low temperatures. Common Conductors* Shield Wires: Jacket Solid or Stranded Silver Coated Copper FEP Silver Coated Copper Covered Steel PFA Silver Coated Copper Silver Coated Copper Alloy *Other conductor materials may be used to give maximum strength, flexibility and conductivity properties to completed cable.
