Abstract (en)

[origin: WO9738556A1] An electric heating element (10) having a circular sheath (11) and a resistance element (12) is filled with granular dielectric material (13) which is initially loosely packed by vibration only and then compacted by imparting a non-circular cross section to the sheath (11) so as to reduce the cross-sectional area without any significant change in the perimeter of the cross section of the sheath (11).
