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
  • Low DC corona inception, particularly after numerous temperature cycles
  • 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.  Teflon tape wrapped cable, which is similar to FEP in dielectric strength and corona inception, is difficult to bond to because of its multiple spiral cross section, irregular surface and variations in diameter.

FEP cable should not only be considered for use in cable assemblies, but as high voltage hook up wire within encapsulated high voltage power supplies, TWTs and transformers.
 

Note: Pre-conditioning of FEP wire or cable is recommended because FEP insulation will shrink when exposed to temperature cycling. Pre-conditioning should be conducted in an air circulating oven at 204°C (400°F) for one hour. Pre-conditioning should only be performed on cut lengths prior to stripping and any termination procedure. No attempt should be made to condition wire or cable in bulk form or while spooled.
