FIELD: electrical engineering. SUBSTANCE: electric heater has resistive member with master slots dividing it for several parts connected in chain. Besides, it has at least one additional slot bending round master slots and dividing every separate member for two parts with equal current pass cross-section. Master slots ends can be made with insert members made from different more electric conductive material or with thickenings made by same resistive material. EFFECT: higher operating life, less material spend. 2 cl, 10 dwg
