Abstract

The present invention relates to electrical floor heating cable and in particular to cables generating acceptably small electromagnetic fields. The cable of the invention has a first, near end and a second, far end and comprises within an outer protective sheath (4) a cable core consisting of
  • a central resistance conductor (1)
  • a concentrical sheath of insulation material (2) surrounding the resistance conductor, - as well as
  • return conductor means (5) arranged to be interconnected with the resistance conductor in the far end of the cable.
The return conductor means consists of at least two separate conductors (5;5a-5c;10,11;15,16,17) which are distributed in the cable core. The return conductors are preferably embedded in a common insulation sheath (3) arranged over the resistance conductor sheath (2).
