Features

  • Type LLT heater cable is parallel, self-regulating with a radiation crosslinked conductive heating core extruded continuously over two parallel 10-gauge bus wires. A primary dielectric jacket is thermally bonded to the heating core to prevent moisture pe
  • Operating principle: The heating core varies power output inversely with temperature at every point along the heater length, reducing any heat build up at portions of the piping system. This feature also permits the heater to be overlapped without creati
  • Voltage ratings: 240 Vac products are suitable for use on supply voltages of 208-277 Vac. See catalog pages for details.
