Vitreous Silica Insulated Cable – TEW&C HG-HG90


  • Flexible – continuous use up to 1800F(982C)
  • Provides accurate temperature measurement
  • According to AMS2750E load thermocouple made from calibrated spool thermocouple wire up to 2000 feet do not need to be calibrated individually
  • According to AMS2750E on single use load thermocouple SAT test is not required (special procedure on instrument calibration is to be implemented)
  • Very useful as TUS test thermocouple

Vitreous Silica fiber designed for extreme temperature applications. Vitreous Silica fiber in this design is braided with thicker insulation on the individual conductors and the jacket giving a continuous temperature rating up to 1800 Degrees F (982 Degrees C). The vitreous silica fiber is flexible throughout the extended temperature range but is not recommended for application that are highly abrasive in high temperatures. The high temperature limit of Vitreous Silica allows it to be used in areas where temperature is higher than the upper limit of fiberglass braided wires.
