The KTV family of nVent RAYCHEM self-regulating heat trace cables provides solutions for industrial pipe freeze protection and process temperature maintenance applications requiring high power output. RAYCHEM KTV heat trace cable can withstand temperatures up to 482°F (250°C) and provide process temperature maintenance to 300°F (150°C). The heating cables are configured for use in nonhazardous and hazardous (classified) locations, including areas where corrosives may be present.

The power output of self regulating electric heat tracing depends on the heating cable temperature and can provide up to 20 W/ft. at 50°F (10°C). RAYCHEM KTV heat trace cables meet the requirements of the U.S. National electrical Code and the Canadian Electrical Code.

Technical Specifications

  1. The heating cable shall consist of two 14 AWG nickel-plated copper bus wires, separated by a fluoropolymer spacer and helically wrapped with a self-regulating fluoropolymer fiber that controls power output so that the cable has an unconditional temperature identification number (T-rating) of T2C (446°F or 230°C) or lower 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 exposure (maintain) capability up to 300°F (150°C) and intermittent exposure capability up to 482°F (250°C or 250 psi steam), as manufactured by nVent.
