Overview

Series resistance trace heating cables for frost protection and temperature maintenance

RAYCHEM XPI polymer insulated (PI) series resistance trace heating cables for frost protection and temperature maintenance applications requiring long circuit lengths.

XPI series resistance heating cables allow for circuit lengths that exceed those of parallel heating cables(typically < 250 m). This makes them particularly suitable for long pipelines and large tanks / vessels. Polymer insulated (PI) trace heating cables can easily be terminated in the field.

  • Continuous withstand temperature 260°C, intermittent 300°C (1000 h cumulative)
  • Available in a wide resistance range to cover most applications
  • Power output up to 35 W/m (power output by design)
  • Approved for use in hazardous areas
  • Impact resistance 4 Joule as per EN 60079-30

Key benefits:

  • Requires fewer circuits by allowing circuit lengths up to 5 km from single power supply point
  • Highest reliability and lifetime expectancy in the most severe environments
  • Excellent chemical resistance
  • Easy to terminate in the field
  • Highly reliable connection kits (cold applied)
  • 10 year warranty available

Unlike many other series resistance trace heating cables, XPI insulating jackets use a unique PTFE/ high-temperature fluoropolymer sandwich construction. PTFE retains its mechanical strength over the entire temperature range offering a variety of benefits. It significantly reduces the risk of typical failure modes of PI cables such as conductor displacement over time at elevated power and temperatures.
