abstract |
The invention relates to a heating film (1) having an electrical connection to which three-phase current is supplied. Said film (1) is characterized in that at least a portion of the supply circuits (P1-P3, P'2, P'3) extend in parallel along at least one side of the heating film (1), wherein means (7-9, 11-19) are provided for preventing the overlapping of at least one supply circuit by a circuit (P2, P3, P'2, P'3) supplying a respective resistive element (2a-2c, 3a-3c, 4a-4c, 5a-5c). The invention can be used in the field of heating. |
