Fluorinated Ethylene Propylene (FEP) offers exceptional dielectric properties that standoff high voltages at smaller diameters in comparison to silicone wire. FEP has a robust molecular structure, which makes it best suited for use in high temperature or harsh environment applications. Teledyne Reynolds' FEP high voltage wire is tested and highly controlled to offer one of the most trusted FEP wires on the market.

Benefits of extruded fluorinated ethylene propylene (FEP) insulated high voltage wire and cable:

  • Exceptional dielectric strength without the disadvantages common to equally rated silicone rubber insulated wire
  • Wire, cable assemblies and cable bundles have much smaller diameter than silicone wire and, therefore, take up substantially less volume while also having a smaller bend radius allowing the designer to better utilize the space within the system
  • Good corona inception qualities
  • Excellent durability and resistance to dielectric/cooling fluid degradation
  • Inert when exposed to most industrial solvents and chemicals
  • Meet NASA low outgassing TML and CVCM levels 
  • Not prone to "pin-holing" and high voltage punch-through when the cable surface is abraded or when strands break during in-field use 
  • More resistant to damage when making contact with sharp edges, although this should be avoided when designing high voltage systems
  • While difficult to bond to, with the use of TRI's proprietary surface preparations and coating processes, Ready-to-Bond™ versions are available that offer an excellent silastic bond.​

In the event that an off-the-shelf solution doesn't fit your specific high voltage interconnect needs, Teledyne Reynolds has a rich history of developing custom, programme specific solutions, including hybrid connectors and cable assemblies combining optics, signal and high voltage. This process is aided by a combination of solid modelling, E-Field simulation software and an internal model shop.
