Thermocouple Extension Wire | PVC Insulated Cable – TEW&C UP/ALPTWK


  • Continuous use up to 221F (105C)
  • Flame Retardant
  • Excellent Dielectric Strength
  • Good Moisture, Chemical and Solvent Resistance
  • 100% Continuous Drain/Shield Contact
  • Economical Construction

Overall Shield

PVC twisted/overall shielded thermocouple cable is ideal for systems sensitive to induced voltage and electrical noise. The twisting of the conductor and the Aluminum/polyester taper shield provides protection against cross talk, static and magnetic noise in instrumentation circuits. Conductors are insulated with color-coded PVC, then twisted with a tin/copper drain wire. Next, an Aluminum Mylar tape is wrapped around the wires, followed by a final layer of overall PVC jacket. The wire is UL listed for Power Limited Tray Cable (PLTC) 300V applications and meets NEC Article 725 Class I, Division 2, hazardous locations and NEC 725 for use in Class and Class 3 Circuits.
