Self-regulating heating cable
HEATING CABLE CONSTRUCTION
The nVent RAYCHEM HTV self-regulating heating cable is designed for freeze
protection or process temperature maintenance of pipes and vessels with very
high continuous operating temperatures (205°C).
Maximum exposure temperature is 260°C.
The HTV cable has a solid construction with a high power retention (HPR)
heating core and pressure extruded electrical insulation. It is then
integrated with a robust metallic braid and a chemically resistant
fluoropolymer outer jacket.
The innovative heating core technology and design result in:
- Superior thermal conductivity
- Super stable power output for long operational life
- Ease of stripping, flexing and installation
- Long circuit lengths for minimized total installation cost
Power retention: At least 95% after 10 years of simulated product life at
maximum continuous operating temperature (205°C).
Certified for use in hazardous and ordinary areas and comes with a 10 year
product warranty programme.
Design life: 30 years or more depending on application.

The above numbers are for circuit length estimation only. The maximum circuit length is for one continuous length of cable, not the sum of segments of cable. For more detailed information please use the nVent TraceCalc design software or contact your local nVent representative. nVent requires the use of a 30 mA residual current device to provide maximum safety and protection from fire. Where design results in higher leakage current, the preferredtrip level for adjustable devices is 30 mA above any inherent capacitive leakage characteristic of the heater as specified by the trace heater supplier or alternatively, the next common available trip level for non adjustable devices, with a maximum of 300 mA. All safety aspects need to be proven.
