SPEC 42235

ETFE/ETFE Instrumentation Shielded Triads Tray Cable

Flexible Instrumentation - Shielded Triads, 600 Volts 150°C Dry Special Applications



  1. Conductor:Class B stranding per ASTM B8. Tinned, annealed copper per ASTM B33
  2. Insulation:Extruded ethylene -tetrafluoroethylene (ETFE)
  3. Twisted Triad:Three conductors twisted together with a drain wire and alum/mylar shield
  4. Shielding:Aluminum mylar shield and drain wire is applied over the core
  5. Overall Jacket:Extruded ethylene -tetrafluoroethylene (ETFE)

Applications and Features:

For use as a 600 volt, Multi Pair instrumentation cable where flame retardance, Moisture/Chemical resistance, and high temperature rating is critical. Cable can be installed in free air, in raceways or direct burial. The cable is also approved for damp or dry locations as well as Class 1 Division II industrial hazardous locations per NEC 501-4(b) for (UL) Type tray cables (TC).

Temperature rating of 150°C dry for special applications. Excellent cut through resistance, electrical properties, chemical resistance, resistance to fluids, and flame resistance. Resistant to crush, compression and deformation. Low coefficient of friction makes installation easier. Good mechanical strength. Flexible. Triads are black, white and red with pair number printed on the white conductor.
