Abstract

PURPOSE: To obtain a sheathed heater possible to be commonly used at high temperatures and having a superior heat resistance by coating a mixture made of specific substances on a heat-resistive electrical insulating material filled between a heating coil and a sheathed metal pipe.
CONSTITUTION: As to a sheathed heater constituted by filling heat-resistive electrical insulating material 14 between a sheathed metal pipe 13 and heating coil 11 equipped with glass bars 12 on both ends, water repellant 15 made of a mixture of silicone resin with a filler consisting of calcium compounds and silicon dioxide is applied onto heat-resistive electrical insulating material 14. Said water repellant 15 is constituted by mixing, for example, 10 - 70 weight % of fillers consisting of 20 - 80 weight % of silicon dioxide and 20 - 80 weight % of calcium dioxide, into 30 - 90 weight % of methyl silicone resins. Thus, a sheathed heater having a superior heat resistance and free from the deterioration in insulation even in high temperature environment is obtained.
