QTVR Self-Regulating Heating Cable

nVent RAYCHEM QTVR self-regulating trace heating cables are suitable for freeze protection of large pipes/vessels with high heat loss, and for process temperature maintenance applications without steam-cleaning requirements, up to 225 °F/110 °C. The

fluoropolymer outer jacket (-CT) provides high chemical resistance against aggressive organics and corrosives.


  1. The heating cable shall consist of two 16 AWG or larger nickel-plated copper bus wires, embedded in a self-regulating polymeric core that controls power output so that the cable has a temperature identification number (T-rating) of T4 (275°F or 135°C) without use of thermostats.
  2. A ground-fault protection device set at 30 mA, with a nominal 100-ms response time, shall be used to protect each circuit.
  3. The heating cable shall have a tinned copper braid with a resistance less than the heating cable bus wire resistance as determined in a type test (ASTM, B193, Sec. 5). The braid shall be protected from chemical attack and mechanical abuse by a fluoropolymer outer jacket.
  4. The heating cable shall have continuous and intermittent exposure capability up to 225°F (110°C). For detailed product specifications, please refer to the product datasheet.
