Series Resistance heating cables have to be individually designed into particular length and load configurations and so are not as versatile as parallel cables.

However, an advantage is that long circuit lengths are possible. Typically 3-phase Longline heating cables require electric supply points only at multi-kilometre intervals. So the major use for series heaters is long pipelines.

We can produce series resistance heating cables within the following ranges:

  • Up to 600 Volts 3 phase
  • Up to 180°C withstand temperature
  • Up to 60 W/meter of output

We normally supply heating cables with a braid and outer jacket but cables can also be supplied with just a braid.  Please ask or see datasheets for more information.
