The invention relates to the field of electric heating, and in particular to a lead device for a voltage heating element. The lead device of the voltage heating element comprises: an electric heatingouter tube, wherein the inner cavity of the electric heating outer tube is filled with an insulating powder; an insulating sleeve, wherein the front end of the insulating sleeve penetrates the insulating powder from the rear end of the electric heating outer tube; and an electrode rod, wherein the insulating sleeve is wrapped on the electrode rod, and the front and rear ends of the electrode rod are exposed outwards. The lead device of the voltage heating element increases the creepage distance and the electrical clearance to meet the electrical safety requirements for medium and high voltageapplications.
