Raychem KTV2-CT Self-Regulating Heating Cable (not stocked) – see XTVR2-CT
Self-regulating heating cable with fluoropolymer outer jacket for process temperature maintenance up to 150 °C and intermittent exposure up to 250 °C, approved for hazardous areas. No longer part of our stocked range; the closest current alternative is XTVR2-CT. Available on request for projects.
Choosing the right self-regulating heating cable
Each RAYCHEM cable type is optimised for a different temperature range and application. As a self-regulating (or power-limiting) cable, it varies its heat output along its length in response to the surrounding temperature, so it cannot overheat or burn out — even when overlapped.
- BTV – Freeze protection and low-temperature maintenance up to 65°C. The everyday choice for pipes and vessels.
- QTVR – Higher output than BTV for freeze protection and process maintenance up to 110°C, ideal for larger pipes with greater heat loss.
- HTV – High-power output for demanding process maintenance at elevated temperatures.
- KTV – Process maintenance up to 150°C on pipes and vessels that require steam cleaning.
- XTVR – Robust performance for high-temperature applications and frequent steam cleaning.
- VPL – A power-limiting cable for high-temperature process maintenance, delivering high output while reducing the number of circuits required.
All cables are approved for hazardous areas (Zone 1, 2, 21 and 22) and supplied cut-to-length. If you are unsure which type suits your application, contact our team for support with cable selection and system design.
